The Mw7.3 Landers, California earthquake occurred on June 28, 1992 (USGS page). It is known for a number of interesting features including significant foreshocks and a complex multifault rupture. I was very much interested the surface rupture pattern and had the good fortune of responding quickly to the event with Dallas Rhodes as well as my fellow graduate students. To be there right after the event (in the rather hot summer Mojave Desert) was very exciting. We worked along the Emerson Fault [...]

I'm going to visit my son in California and I have two things on my mind - earthquakes and drought.  Both are the result of high-energy processes in our good old Earth. The first is drought.  California has had a very long drought so far.  However, looking at tree rings and such, 100 year droughts are common, and very long droughts have wiped out ancient civilizations.  It is the natural

Almost all of you will have seen the tragic news coming from Nepal. A magnitude 7.8 earthquake struck the region between Pokhara and Kathmandu, with at least 1000 killed at the time of writing. This number is likely to go up in the coming hours and days as the true extent of the devastation becomes apparent. Here we note some recommend reading and news sources on the event: UNISDR blogs from 2012 and today, giving valuable background information on the disaster risk reduction progress that [...]

An M7.8 earthquake occurred 77km (48mi) NW of Kathmandu, Nepal April 25, 2015. It apparently occurred along the Main Himalayan thrust fault system which accommodates the substantial convergence between India and Eurasia. According to the USGS, the last great earthquake in this region along the Himalayan arc was about 240 km southeast--the 1934 M8 1934 Nepal-Bihar earthquake--and caused major damage to Kathmandu and caused about 10,600 casualties. This 2015 earthquake is likely to have been [...]
