Geologic causes vs geologic triggers

There’s a great, new online news article by Science’s Richard Kerr about the role of the Zipingpu Dam in last year’s Wenchuan earthquake. A new article in Geophysical Research Letters (which I haven’t read – my library doesn’t have access to GRL) tests the plausibility of water as a trigger for the Wenchuan quake, and…

Go to Dave’s Landslide Blog for full details about this. I don’t have access to the paper. According to Dave Petley, there’s a new paper in Nature Geoscience about the Slumgullion landslide. Slumgullion is in my greater neighborhood – it’s in Colorado’s San Juan Mountains, between Lake City (former home of Alferd Packer) and Creede…

And, at 10:15 am Pacific time, it’s California’s second annual earthquake drill – the Shake Out. I don’t live in California, but I might crawl under my…

One year ago today, a M 7.9 earthquake struck the Chinese province of Sichuan. It was horrific. I don’t have anything profound or helpful to say about it myself, but I want to pass on links to other remembrances: Berkeley SeismoBlog explains the tectonics of the earthquake, and the possibility (raised in the Chinese journal…

Along with the stories of tragedy in Italy, there are also stories that the earthquake was predicted, and that the predictions were ignored. Was the tragedy made even worse by authorities who wouldn’t listen to a scientist who knew what he was talking about? Now, I’m not a seismologist, but I know a little about…
