Geologic causes vs geologic triggers
Posted by Kim Hannula on November 9, 2009 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…
Slumgullion movement due to atmospheric pressure?
Posted by Kim Hannula on November 1, 2009 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…
The Great California Shake Out, and the World Series Quake… 20 years later
Posted by Kim Hannula on October 14, 2009 There’s a lot going on the online geo-world tomorrow. It’s Blog Action Day, and the subject is Climate Change. It’s Earth Science Week’s first Women in Geoscience day. 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…
Remembering the Wenchuan earthquake
Posted by Kim Hannula on May 11, 2009 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…
Anniversary of the great San Francisco earthquake of 1906
Posted by Kim Hannula on April 18, 2009 I’ve been awakened by an earthquake, but it was only M 4. I can’t imagine what it would have been like to be in San Francisco 103 years ago this morning, when a M 8-ish earthquake struck at 5:12 am. Shaking ten times stronger than the Loma Prieta earthquake – I couldn’t stand up in…
Earthquake prediction and the L’Aquila earthquake
Posted by Kim Hannula on April 7, 2009 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…
