I haven't seen him for a number of years, but always think of him fondly. -- And you're right, eastern Nevada is different. It's always seemed surprising to me that there aren't more earthquakes, and large ones, in the B&R.Silver Foxhttps://www.blogger.com/profile/03131032620978696727noreply@blogger.comtag:blogger.com,1999:blog-5211670216140060946.post-62350793972537719852008-02-22T22:24:00.000-08:002008-02-22T22:24:00.000-08:00I was a grad student at the University of Nevada, ...I was a grad student at the University of Nevada, and I fondly remember flying early in the morning back in 1985 with Burt Slemmons investigating for recent scarps in the mountains near Elko, and there were some young-looking scarps in the region. But it is striking the almost complete lack of historical seismicity in the entire region of northeastern Nevada.Garry Hayeshttps://www.blogger.com/profile/00531226195147986457noreply@blogger.comtag:blogger.com,1999:blog-5211670216140060946.post-743673880478627972008-02-22T10:24:00.000-08:002008-02-22T10:24:00.000-08:00I guess it's good to remember that the entire Basi...I guess it's good to remember that the entire Basin and Range of Nevada and Utah is geologically active. Besides the obvious Fairview Peak "earthquake fault" along Highway 50, another good fault scarp is the Crescent Valley scarp southeast of Battle Mountain and more or less north of Cortez. Although the most recent movement on that fault is suspected to be about <A HREF="http://www.agu.org/pubs/crossref/2004/2003TC001528.shtml" REL="nofollow">2.8 ka</A>, that is quite recent considering the 17 m.y. history of the faulting in the region.<BR/><BR/>Didn't feel a thing, though.Silver Foxhttps://www.blogger.com/profile/03131032620978696727noreply@blogger.comtag:blogger.com,1999:blog-5211670216140060946.post-36570689089309746752008-02-21T19:54:00.000-08:002008-02-21T19:54:00.000-08:00I found the GPS study that I had heard discussed a...I found the GPS study that I had heard discussed at GSA: <A HREF="http://www.sciencemag.org/cgi/content/abstract/283/5408/1714?ijkey=210c0cdfb15e1cf8c779776aab1c8aea364aa621&keytype2=tf_ipsecsha" REL="nofollow">Science 1999</A>. The survey was done along US 50 rather than along I-80, but there's a step in the GPS data near the longitude of today's earthquake.<BR/><BR/>I will be curious what the modelers see in the data.Kimhttps://www.blogger.com/profile/07738706550175991130noreply@blogger.com
