2012 Texas earthquakes may have been man-made

Analysis of a series of earthquakes in East Texas in 2012 has found it plausible that the earthquakes were caused by wastewater injection. Previous studies relied on the timing and proximity of wastewater injection to earthquakes to decide if earthquakes were induced by human activity. This was the first to simulate the mechanics of an earthquake generated by water injection for this site.

Seismic risk in eastern Mediterranean higher than previously estimated

The eastern Mediterranean is more seismically active than previously assumed, a new study finds. On a geological time scale, seismic activity around the island of Crete has generated large earthquakes in bursts, potentially increasing the future risk for earthquakes and tsunamis in the region.

Shake, Rattle and Frack

A new study was published today in the Bulletin of the Seismological Society of America, by three USGS scientists, and it’s the latest in a growing number of scientific studies that show that deep injection of waste water during fracking is causing earthquakes. It seems pretty likely that a quake will do damage in a fracking zone soon, and all this science will be moved into a courtroom. The graph …

Intrigued by Earthquakes and Volcanoes? It’s Easy to Become Geologically Literate

Meteorologists in general do not know much about Geology, but broadcast mets are usually the first person newsroom producers (and the public) turn to when there is an earthquake, tsunami, meteor showers etc.  I had a couple of great courses in Geology working on my masters, and a field trip to the Washington State was a fantastic learning experience, and it left me with a lifelong fascination of rocks and …
