I had this title in my Earthquakes g+ collection.  As you know, g+ is for people who don't talk much, and that's a lousy basis for social network.  It will never pull in more money than it costs. Basically, the title refers to the massive purge of earthquake intellect from that fine state.  Nobody will now touch it with a barge-pole, except me.  The last investigative journalists from Tulsa

I'm really going to say that the rate of increase of magnitude is down.  Kansas is enjoying a summer holiday, but Ok. City had a big flurry last week.  It's interesting to think how the rate should go up as the earthquakes become larger.  Since the magnitude scale is exponential, and the fault area goes by the square, some things should slow down.  Stress corrosion would go on a steady rate

Driving Through the Most Dangerous Plate Boundary in the World: A Compilation of Fear(somely cool geology)

Without a doubt, subduction zones are the most dangerous plate boundaries on the planet. Divergent plate boundaries produce earthquakes and occasional volcanoes, but nothing on the fearsome scale of the calderas and stratovolcanoes and magnitude 9 earthquakes experienced at convergent boundaries. Transform boundaries produce earthquakes, but they are magnitudes smaller than those produced

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
