Lamont-Doherty Earth Observatory scientist Ben Holtzman grew up discovering science through interactive exhibits in San Francisco’s Exploratorium and now provides a similar experience for others. Holtzman designs immersive shows that allow people to experience what earthquakes and seismic waves look and sound like as they move through and around the Earth. On Monday, November 17th at the American Museum of Natural History Hayden Planetarium, Holtzman and his collaborators will present one of [...]

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 | [...]

Alaskan megathrust fault more active under Kodiak

 US
The 1964 Alaska Earthquake was 9.2 in magnitude and caused dramatic destruction and dramatic examples of surface rupture, subsidence, and liquefaction. New paleoseismic evidence points to a previously unknown earthquake that happened on the same fault segment approximately 500 years ago. This new evidence would change the recurrence interval for the earthquakes on the Alaskan megathrust fault, which would affect seismic hazard in Alaska, but could also increase the tsunami hazard in places as [...]

In order to make sense of the sediment cores that can be retrieved from lakes near to the Alpine Fault such as Lake Christabel, it is worth having a think about what happens to the environment when the fault ruptures in a large earthquake. Under normal conditions, alpine lakes fill up very slowly with sediment that is fed into them by rivers. The particles settle onto the lake bed gradually, to create a sequence of finely layered mud.When an earthquake occurs, a number of consequences affect [...]
