Just now we have had an earthquake of M4.0 that almost nobody felt. This was a mostly normal earthquake (tension) with about half being shear. But, earlier, we had an M4.2 that was strongly felt. This was thrust, with a very small hammer zone.  No fault plane solution could be calculated.  Even a 3.6 thrust had a greater narrow intensity than the recent 4.0 Now, the USGS believes

There is lots of talk in northern Arizona these days about earthquakes, since a moderate tremor shook Oak Creek Canyon (above) on Sunday, November 30.This recent event makes me recall the time in 1993 when I taught a course at Yavapai College called "Earthquakes and Volcanoes of Northern Arizona." My research into providing lecture material for the class made me aware how this part of Arizona is very susceptible to strong temblors, as evidenced by a swarm of quakes that occurred near [...]

This is from the Southern Ontario Seismic Network (SOSN) that I helped out with at one time.  It's probably the best seismic network east of California.  Combined with all the deep seismic reflection data, it has helped formulate my ideas of what is happening here and in the States. Note the very tight association with water.  Basically, no water, no earthquakes, with some exceptions.

My inbox has been flooded with these earthquakes.  I had set my trigger to M4.0 in the US, just to catch the next OK significant earthquake, but it's all this Nevada crap. That's a 10 km square.  Apparently these things are quite common in the region, always topping in a few weeks with some M5's.  The dimensions limit the magnitude.  I've come to the conclusion that such swarms are always

The Deform2015 school on Active Deformation, Faults and Earthquakes from Measurements to Models will be held in Southern France from 7-13 February, 2015. Over the past years, considerable advances have been made in observing crustal deformation at scales of seconds to thousands of years. However, a unified view of the earthquake cycle is still missing. The thematic school aims at bringing together students and scientists working on different aspects of active faulting and earthquake processes. [...]

There is a report of activity in 1936, however this is now assumed to have been from nearby Reventador volcano. The volcano itself does not appear to have been active during the Holocene, so it would be another in a line of eruptions of volcanoes with no historical eruptions.Fumeroles, and hot springs are found on the volcano.The Smithsonian GVP reports the following:Cerro Negro de Mayasquer | [...]
