Welcome back from all the EGU Vienna, SSA Pasadena and INQUA Fucino meetings during the last days. You have missed a lot of stunning images. Today is Friday and here are your links!
We had quite a few links on North American seimology and earthquake hazard in the past – here is Julian‘s post on Precarious Boulders and Earthquakes in New Zealand. He introduces Mark Stirling’s work on the earthquake history of fragile boulders (or rather the history of these boulders without an earthquake) and his research on what I would like to call boulder paleoseismology!
I really like this weeks Imaggeo on Mondays, because it’s a photograph of the so-called Earthquake Lake, originally named Sarez Lake. Due to a massive landslide associated with the Ms 7.4 (IX) 1911 Pamir Earthquake, the Murgab River valley (also Bartang River valley) was blocked and the lake developed. There’s way more to read on this topic, and even if you’ve known the lake and its history before, there is still this beautiful photograph for you to enjoy:
Staying in Asian high mountain ranges, watch this great video by Ghazoui Zakaria from ISTerre, France: Inside Himalayan Lakes. The video is on Ghazoui’s research on lake sediments and won the Communicate Your Science competition!
Another video catched my attention this week – it was footage on the Calbuco eruption during sunset. It again shows how beautiful these dangerous natural hazards can be:
And here the same volcano when it was still “sleeping”:

And here are even more stunning and interesting pictures on this eruption:

And, last but not least, read this introduction on Fracking, Injecting and Earthquakes on Seismo Blog. And note their announcement:
If you want to learn more about fracking, injection wells and the risk of earthquakes associated with both, come to the Berkeley campus next Wednesday, April 29. Greg Beroza, an Earth scientist from Stanford, will give BSL’s annual Lawson Lecture under the title “Induced Earthquakes in the 21st Century”. The talk will start at 5:30 pm in the Banatao Auditorium in Sutardja Dai Hall (Citris-Building).
Have a nice weekend!
