41st Anniversary of the Eruption of Mt. St. Helens: It Still Matters and So Does Science


It is the 41st anniversary of the eruption of the St. Helens volcano and as I think of those days, I realize that even though a majority of the population wasn't even alive at the time, the volcano still matters. Not because of the potential for future eruptions (although that remains a distinct possibility), but because of the way we process and deal with the natural hazards that we all face, no matter where we live. This is kind of a recurring post that I've modified over the years.


When the volcano began rumbling and sending ash into the atmosphere, we had only a few avenues to get information, mainly television news, radio, and newspapers. I think now how limiting these sources were compared to the nearly instantaneous delivery of news over the internet in the present day. We can look up earthquakes just moments after they happen, and webcams allow us to monitor volcanoes around the world in real time. There is both good and bad in this profound change. There were terrible sources of news in those olden days, like the Weekly World News or the National Enquirer, but they pale in comparison to the sewage found on the internet today. Back then, national news outlets and newspapers practiced careful journalism in most instances, but it often seems today that the only reward for excellence and honesty in reporting is decreased ratings and falling revenues. To get attention in a crowded internet environment media outlets have to dress their stories as shiny objects and provide them with the worst possible clickbait titles. In the olden days we often had to wait impatiently for information about natural disasters, but the information that came through the media was more likely to be vetted and checked for accuracy. The journalistic filters today are completely gone in many media sources, and it can be difficult to distinguish between the trash and the truth.




There are so many conspiracy theories floating around today about natural disasters and potential disasters. The eruptions of Steamboat Geyser in Yellowstone National Park numerous times after years of quiescence caused a blizzard of posts on the internet pondering whether Yellowstone has been disturbed and may blow as a "supervolcano" eruption soon (and we'll all die). The same has happened after a number of recent small earthquakes. But a reading of the reality-based data says that Yellowstone caldera has not had a lava flow or eruption of any kind in 70,000 years, and no knowledgeable geologist sees any evidence of precursors to any new eruptions. A few years back, an earthquake and an internet video of a group of bison running "away" from Yellowstone caused the same kind of internet speculation (it turns out the bison were running towards the caldera).




Of course it is true that the Yellowstone caldera was born in one of the most colossal eruptions ever recorded. Learning the story of the eruption of the Huckleberry Tuff is fascinating. It brings an entirely new appreciation of the incredible scenery to be observed in a place that contains 70% of all the world's geysers. It should be enough. But there are so many individuals out there who would like to make a buck by scaring people needlessly. And there are too many gullible and ignorant people out there who can't pick rational accounts out of the confusing mix of conspiracy theories that exist on the internet.




And then there is the Big Island of Hawai'i. There were some serious and tragic things going on in 2018 when the longest eruption in recorded history reached a climax. The activity endangered lives and destroyed homes as Kilauea underwent major changes from the "norm" of the eruptions that had been ongoing for the last 35 years. One of the truly awesome sights I have ever seen was the collapse of a portion of the Kilauea Caldera into a gigantic pit that reached a depth of 1,800 feet. It stabilized for a year or so, even forming a lake (of water) at the bottom, but then a few months ago the eruptions started again, filling the pit with 700 feet of roiling molten basalt. 

The U.S. Geological Survey and Hawaiian civil defense authorities did a pretty good job of providing up-to-date information about the latest activity, but that didn't stop all kinds of stories from popping up on the internet about the "Ring of Fire" which has nothing at all to do with Hawai'i. It was just too easy to pick up stories of eruptions in Alaska and Indonesia and think there was a pattern of increasing volcanism or earthquake activity (OMG, a magnitude 6 quake in the Kermadec Islands and an eruption at Mt. Cleveland in Alaska! It's a pattern and therefore Seattle will fall into the sea very soon!). The problem is one of perspective: if you had signed up for earthquake notifications and volcano advisories from the USGS or other geologic research institutions, you would have realized that these things happen all the time, and that a cluster of events is not unusual.


It's one thing to make up stories about normal volcanic activity to scare people. One can argue that they are ultimately harmless because the eruptions aren't actually taking place or hurting anyone. But there are real-world consequences of ignoring journalistic standards. Many of those who make their money with false headlines about such things will also traffic in climate change denial. When science becomes a matter of believing whatever one wishes, the very real problem of global warming becomes just another "scare" story, and the alarm bells being sounded by climate scientists become just more noise in an internet full of noise. But the predicted real-world consequences are happening now, and action is needed to counteract the changes or to stop them. But it has become too easy to ignore the problem because it is so incremental and slow-acting. It just can't compete with the shiny baubles and clickbait on the web.
People in Hawai'i mostly trusted the geologists who studied the volcanoes all their lives and thus made the correct decisions about evacuating homes and businesses. In the same way they trusted the seismologists when a tsunami threatened the islands in 2011 after the massive earthquake in Japan. No lives were lost when the tsunami hit because people had evacuated the low-lying areas. The wave surge was 8 feet deep in places and caused millions of dollars of damage. Many people could have been killed, but they accepted the authority of the scientists who predicted the timing and magnitude of the seismically induced waves.

There has been one characteristic about the natural disasters that I've described above. They were local events that profoundly changed lives, but in large and yet limited regions. When earthquakes and volcanic eruptions strike, survivors can turn to other regional state and national governments for support, since those entities were not so badly affected. Now we face a different set of natural disasters: those that affect the entire planet. Pandemics and climate change affect all of us. Witness the spread of the COVID-19 virus last year to literally every corner and every country of the planet in a matter of weeks.

Scientific experts have long predicted the emergence of dangerous new strains of viruses, and previous administrations used the best scientific minds to prepare for their inevitable arrival. But those administrations were replaced by one that denigrated scientific expertise and fired the experts who could have crafted an appropriate national response to the COVID-19 virus. And last year we saw the result: nearly 600,000 deaths in the U.S. with more to come, lack of critical medical supplies in the critical early months, and no coordinated federal response, even once vaccines became available. Even worse was a propaganda campaign that convinced people that the disease was not as bad as it clearly was, and worse still, that the vaccines were some kind of insidious plot. Other countries listened to their scientists and saved countless lives. I thank the heavens that the country ultimately elected an administration that is being guided for the most part by science in their decision-making processes.

And that's why the Mt. St. Helens eruption of 1980 matters today. Scientific expertise matters. The pandemic (and others to come) will be a continuing problem in our interconnected world. Climate change is proving to be an even more profound danger to society than any virus, earthquake or volcanic eruption. We need people to give climate scientists the same kind of respect they give geologists when volcanoes are rumbling and smoking. They are the ones to listen to, not the hucksters on the internet who are out to make a buck, or trying to protect those industries that make their profits off of producing greenhouse gases. We seem to talk little these days about integrity and striving for excellence, but scientific researchers are among those who still have those traits. There are always exceptions, but I would trust a scientist over a politician every time (unless it is clear that the politician knows how to listen to a scientist).




There is a sign seen at some of the March For Science protests that have been happening around the country: "At the start of every disaster movie there's a scientist being ignored". Unfortunately, it is too true in real life as well.

Travels in Cascadia: Burial Mounds of the Kings of the Rohirrim? The Mima Mounds of Washington


NOTE: If this post seems familiar, it should be. I posted it just a month ago. I'm re-posting (with minor changes) to place it in the proper order of the current blog series. 

One of the vivid images in my mind of the Lord of the Rings Trilogy was the resting place of the Kings of Rohan. They were buried in mounds, and the mounds were covered by the white flowers called SimbelmynĂ«. I couldn't help think of the Kings of the Rohirrim when we arrived at the Mima Mounds Natural Area Preserve near Tumwater, Washington.
When European settlers reached the region, some of them thought that these unusual features were indeed Native American burial mounds. But when no further evidence could be found supporting the idea, they looked for other explanations. And didn't find many...
The things we don't know about our planet are, well, not known. But geologists are the first to say that the unknowns are legion. Many aspects of Earth are still a mystery. Lots of the mysteries lie hidden deep in the crust and mantle, or on the deepest parts of the ocean basins. But some mysteries are still right there in front of us, and mima mounds are one of them.

Mounded topography forms in a number of places across the central and western United States in a number of different geological environments. Although they share some similarities, it is possible that they originate from several different processes. Ideas range from the mundane to the exotic (and unlikely). Most of them occur when a fairly thin layer of soil covers a harder layer or substrate underneath. They tend to be just a few feet high, and occur in concentrations of 8-10 per acre.
The mima mounds of Washington formed at the edge of the massive ice sheet that covered most of Canada and parts of Washington as recently as 12,000 years, and so some hypotheses involve glacial meltwater, or subsurface glacial activity. Some suggest erosion of sediment from around concentrations of vegetation. More esoteric explanations involve disturbances from the vibration patterns of major earthquakes.

Occam's Razor states that among competing hypotheses, the ones that make the fewest assumptions are more likely to be correct (sometimes inaccurately described as the simplest answer is always the best). One of the more reasonable explanations for the mounds may be simply rodent activity. When pocket gophers dug into the shallow soils and encountered harder sediments, they tended to build up the mounds, and the process continued through thousands of generations. Maybe. And maybe it's aliens...
I managed to catch a photo of the mima mounds on approach to SeaTac a few years ago.
In any case, it's a fascinating place to visit. Several trails wind their way through the mounds, and there is an interpretive kiosk with a viewing platform. It is a beautiful prairie setting, with the tweeting of birds, the buzzing of insects...and an air of mystery.
I've been to the mounds in Washington twice, and the first time was in the dead of winter when no flowers were present. This time it was summer and it was a thrill to see the fields of flowers, bringing to mind the tombs of kings and the Simbelmynë.
If you want to visit the site, here are the directions from the park website:

From southbound or northbound Interstate 5, take Exit 95 and turn west on Highway 121 (Maytown Road SW) toward Littlerock. In Littlerock, continue west (forward past the school, past the intersection with Littlerock Road that curves south, and past the mini mart/gas station on the right) onto 128th Avenue. Travel about 0.8 mile where 128th Avenue ends at a 'T.' on top of the hill. Turn right onto Waddell Creek Road and travel about 1 mile. The entrance to Mima Mounds Natural Area Preserve will be on the left. A Washington State Discover Pass is required for parking at this site.

Postscript: Dustin commented when I posted the original last month, and these ideas have some merit...

Great features! My guess is that the mounds developed when glacial outflow preferentially eroded the fissures created by patterned-ground permafrost in a periglacial environment. This photo shows mounds forming from patterned ground in Alaska.

 https://en.wikipedia.org/wiki/File:Alaska_patterned_ground_1973.jpg 

In the case of the Mima mounds, if patterned ground was originally present with hard and frozen polygon centers, and margins/edges that were soft and thawed, then water flowing over the patterned ground would preferentially erode the fissures, while being less destructive to the polygon cores. Sustained flows would likely erode all evidence of patterned ground, but the Mima mounds were likely formed from ephemeral flow events associated with glacial melt near the ice sheet margins. This type of environment is suggested by the kettle lakes visible in the upper right of your airphoto, and the mounds being distributed amongst relict braided river patterns.

Burial Mounds of the Kings of the Rohirrim? Got a Better Idea? The Mima Mounds of Washington

The Eruption of Mt. St. Helens at 39 Years: Why It Still Matters


It is the 39th anniversary of the famed eruption of the St. Helens volcano and as I think of those days, I realize that even though a majority of the population wasn't even alive at the time, the volcano still matters. Not because of the potential for future eruptions (although that remains a distinct possibility), but because of the way we process and deal with the natural hazards that we all face, no matter where we live.


When the volcano began rumbling and sending ash into the atmosphere, we had only a few avenues to get information, mainly television news, radio, and newspapers. I think now how limiting these sources were compared to the nearly instantaneous delivery of news over the internet in the present day. We can look up earthquakes just moments after they happen, and webcams allow us to monitor volcanoes around the world in real time. There is both good and bad in this profound change. There were terrible sources of news in those olden days, like the Weekly World News or the National Enquirer, but they pale in comparison to the sewage found on the internet today. Back then, national news outlets and newspapers practiced careful journalism in most instances, but it often seems today that the only reward for excellence and honesty in reporting is decreased ratings and falling revenues. To get attention in a crowded internet environment media outlets have to dress their stories in shiny objects and provide them with the worst possible clickbait titles. In the olden days we often had to wait impatiently for information about natural disasters, but the information that came through the media was more often vetted and checked for accuracy. The journalistic filters today are completely gone, and it can be difficult to distinguish between the trash and the truth.




There are so many conspiracy theories floating around today about natural disasters and potential disasters. The eruptions of Steamboat Geyser in Yellowstone National Park numerous times after years of quiescence has caused a blizzard of posts on the internet pondering whether Yellowstone has been disturbed and may blow as a "supervolcano" eruption soon (and we'll all die). The same has happened after a number of recent small earthquakes. But a reading of the reality-based data says that Yellowstone caldera has not had a lava flow or eruption of any kind in 70,000 years, and no knowledgeable geologist sees any evidence of precursors to any new eruptions. A few years back, an earthquake and an internet video of a group of bison running "away" from Yellowstone caused the same kind of internet speculation (it turns out the bison were running towards the caldera).




Of course it is true that the Yellowstone caldera was born in one of the most colossal eruptions ever recorded. Learning the story of the eruption of the Huckleberry Tuff is fascinating. It brings an entirely new appreciation of the incredible scenery to be observed in a place that contains 70% of all the world's geysers. It should be enough. But there are so many individuals out there who would like to make a buck by scaring people needlessly. And there are too many gullible and ignorant people out there who can't pick rational accounts out of the confusing mix of conspiracy theories that exist on the internet.




And then there is the Big Island of Hawai'i. There were some serious and tragic things going on last summer as the longest eruption in history reached a climax.

The Mount St. Helens Eruption at 38 years, and Why it Matters Today

I'd love to say I got these photographs of Mt. St. Helens last week when I flew to Seattle, but we flew right over the volcano, so you'll have to settle for the pictures I got on a flyover back in 2006. I did get pictures of Mt. Rainier and Medicine Lake Highland though. In any case, it is the 38th anniversary of the famed eruption of the volcano and as I think of those days, I realize some disturbing things.
When the volcano began rumbling and sending ash into the atmosphere, we had only a few avenues to get information, mainly television news, radio, and newspapers. I think now how limiting these sources were compared to the nearly instantaneous delivery of news over the internet in the present day. We can look up earthquakes just moments after they happen, and webcams allow us to monitor volcanoes around the world in real time. There is both good and bad in this profound change.

In the olden days we often had to wait impatiently for information about natural disasters, but the information that came through the media was more often vetted and checked for accuracy. The journalistic filters today are completely gone, and it can be difficult to distinguish between the trash and the truth.

There are so many conspiracy theories floating around today about natural disasters and potential disasters. The eruption of Steamboat Geyser in Yellowstone National Park five times in two months (after four years of quiescence) has caused a blizzard of posts on the internet pondering whether Yellowstone has been disturbed and may blow as a "supervolcano" eruption soon (and we'll all die). The same has happened after a number of recent small earthquakes. But a reading of the reality-based data says that Yellowstone caldera has not had a lava flow or eruption of any kind in 70,000 years, and no knowledgeable geologist sees any evidence of precursors to any new eruptions. A few years back, an earthquake and an internet video of a group of bison running "away" from Yellowstone caused the same kind of internet speculation (it turns out the bison were running towards the caldera).

But there are so many individuals out there who would like to make a buck by scaring people needlessly. And there are too many gullible and ignorant people out there who can't pick rational accounts out of the confusing mix of conspiracy theories that exist on the internet.

And then there is the Big Island of Hawai'i. There are some serious things going on during the current phase of the eruption. The activity is endangering lives and destroying homes as Kilauea undergoes some major changes from the "norm" of the eruptions that have been ongoing for the last 35 years. The U.S. Geological Survey and Hawaiian civil defense authorities have been doing a pretty good job of providing up-to-date information about the latest activity, but that hasn't stopped all kinds of stories from popping up on the internet about the "Ring of Fire" which has nothing at all to do with Hawai'i. It is just too easy to pick up stories of eruptions in Alaska and Indonesia and think there is a pattern of increasing volcanism or earthquake activity (OMG, a magnitude 6 quake in the Kermadec Islands and an eruption at Mt. Cleveland in Alaska! It's a pattern and therefore Seattle will fall into the sea very soon!). The problem is one of perspective: if you sign up for earthquake notifications and volcano advisories from the USGS or other geologic research institutions, you would realize that these things happen all the time, and that a cluster of events is not unusual.
It's one thing to make up stories about normal volcanic activity to scare people. One can argue that they are ultimately harmless because the eruptions aren't actually taking place or hurting anyone. But there are real-world consequences of ignoring journalistic standards. Many of those who make their money with false headlines about such things will also traffic in climate change denial. When science becomes a matter of believing whatever one wishes, the very real problem of global warming becomes just another "scare" story, and the alarm bells being sounded by climate scientists become just more noise in an internet full of noise. But the real-world consequences are happening now, and action is needed to counteract the changes or to stop them. But it has become too easy to ignore the problem because it is so incremental and slow-acting. It just can't compete with the shiny baubles and clickbait on the web.
People in Hawai'i right now are largely trusting the geologists who have studied the volcanoes all their lives and are thus making the correct decisions about evacuating their homes. In the same way they trusted the seismologists when a tsunami threatened the islands in 2011 after the massive earthquake in Japan. No lives were lost when the tsunami hit because people had evacuated the low-lying areas. The wave surge was 8 feet deep in places and caused millions of dollars of damage. Many people could have been killed, but they accepted the authority of the scientists who predicted the timing and magnitude of the seismically induced waves.

And that's why the Mt. St. Helens eruption of 1980 matters today. Science and scientific expertise matters. Climate change is an even more profound danger to society than any earthquake or volcanic eruption. We need people to give climate scientists the same kind of respect they give geologists when volcanoes are rumbling and smoking. They are the ones to listen to, not the hucksters on the internet who are out to make a buck, or trying to protect those industries that make their profits off of producing greenhouse gases. We seem to talk little these days about integrity and striving for excellence, but scientific researchers are among those who still have those traits. There are always exceptions, but I would trust a scientist over a politician any day of the week (unless it is clear that the politician knows how to listen to a scientist).

There is a sign seen at some of the March For Science protests that have been happening for the last year and a half around the country: "At the start of every disaster movie there's a scientist being ignored". Unfortunately, it is too true in real life as well.

Dear Washington State: All is Forgiven...The Airliner Chronicles Returns

The Pacific Northwest has this problem. It has two particular things in great abundance: trees and clouds. It also has volcanoes, but much of the time the first two obscure the latter. At Christmas I drove to the Seattle area and spent three days, and never laid eyes on Mt. Rainier, the gigantic stratovolcano that looms over the Puget Sound region. In the last week I had occasion to fly to the Seattle area, and being the month of May, I figured I had a pretty good chance of seeing some of the Cascade volcanoes. It started out pretty well as we left Sacramento, since I could see Lassen Peak off in the distance and then it disappeared. The clouds obscured the views all the way to Washington with the sole exception of a brief look at Mt. Adams, and the view below of Mt. Rainier.
Yeah, somewhere in there is the summit of Mt. Rainier.


That was okay. I had four days of walking and driving around Kent and Renton, and figured there would be a view once in awhile of the massive volcano. Nothing doing. There were tantalizing glimpses while driving around, but there were always trees in the way. Washington was disappointing me.
The flight home was scheduled to take off at 7:50PM so I figured there were too many things that would happen to either delay the flight until after sunset, or the clouds would be there again. But we boarded the plane on time and while taxiing down the runway I got the best ground-based picture of the mountain on the entire trip. It wasn't much, but it was something. 
And then we took off. It was hazy, and we took off towards the north and did a long turn towards the south, long enough to make me wonder if we were going to pass Rainier on the wrong side. But as the plane banked there was suddenly a very big mountain in the window, and Washington with all her trees and clouds were immediately forgiven. The mountain was stunning in the evening light.

At 14,411 feet, Mt. Rainier is the tallest volcano in Cascades Range, and is exceeded in volume only by Mt. Shasta in Northern California. It was once even higher, but glaciers have removed 1,000 feet of rock or more from the summit.  Because it is by far the tallest mountain in the Pacific Northwest it is completely covered by the largest mass of glacial ice in the lower 48 states, about a cubic mile (I read somewhere that it contains half of the all the glacial ice in the lower 48, but I can't find the source and would welcome any corrections from those who know such things). Aside from the "normal" threats that volcanoes might present to a given region (lava flows, ash flows, and that sort of thing), the snow makes the mountain far more dangerous. It's not hard to imagine why: any small eruption would melt a vast amount of ice, forming volcanic mudflows called lahars that are capable of flowing for many tens of miles, and threatening many of the cities along the southern part of the Puget Sound. The entire city of Tacoma is built on a mudflow that thundered down the mountain 5,000 years ago. The last major eruption occurred around a thousand years ago, although minor activity may have occurred several times in the 1800s. 

We flew south as the sun was sinking below the horizon and several other volcanoes appeared out of the gloom. Those pictures will come later. By way of explanation, the term "Airliner Chronicles" refers to the very first blog series I ever put together way back in 2008. One of my earliest posts in the series was also an evening shot of Rainier. By some strange convergence, that post received its first and only comment just two days ago!
