A few weeks ago I spent ten days of field work in the Suusamyr Valley in Kyrgyzstan. In the framework of the EwF Project and COMET a team from Oxford (Eleanor Ainscoe, Austin Elliott, Richard Walker) and Kyrgyzstan (Kanatbek Abdrakhmatov, Azat Moldobaev) re-visited the epicentral area of the 1992 MS7.3 Suusamyr earthquake. This thrust earthquake is quite special for it produced intense and widespread secondary earthquake environmental effects (landslides, rockfalls, secondary ruptures, mud eruptions, etc.), but remarkably short primary surface ruptures only. Actually, surface ruptures of several metres height were found near the Suusamyr river, but limited to few hundreds of metres in length. Some 25 km to the west, another set of surface ruptures appeared, which were only about 1 m in height and less than 3 km long. Here are some impressions from our field work.

New reports (on why geology matters), papers (on Nepal and Chile), a video (on Martian debris flows), some tweets and even more. Today is Friday and here are your links!
It’s Friday – but instead of the Friday links I have the story of a giant post earthquake debris flow in the Wenchuan area for you. As I already announced in my last post about the field trip to the Wenchuan earthquake epicenter in frame of the International Symposium on Mega-Earthquake Induced Geo-disasters and Long Term Effects in Chengdu, China, I still wanted to blog about the Qipan gully debris flow that we also visited during the field trip. After giving you some background information I will take you on the hike with us. We will first see massive destruction in the residential area and then have a look at the debris flow deposits and some mitigation structures while climbing up the gully. Come on, let’s go!

The Geoblogosphere is full of links on the Gorkha Earthquake in Nepal – and we have some links on this major event, too. But we found also some few more links on creating beautiful scientific posters, hilarious geomemes, and more. Today is Friday and here are your links!
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!
The Big One covered the news this week – didn’t you notice? We’re back with news and links on the long-term erthquake forecast for California, the reawakened Oklahoma faults, the UN Disaster Risk Reduction conference, an image tournament, and more. Today is Friday and here are your links!
A lot of great papers were published this week, so prepare for some reading this weekend. The South Napa Earthquake, drilling the Alpine Fault, earthquake supercycles and a landslide handbook. Today is Friday and here are your links!
And again it’s almost the start of a weekend! I collected some nice links for you, I hope you like them. Today is Friday and here are your links!
Welcome back! Fewer links, a bit more to read! Do roads mean landslides are more likely? What were the Great Survey geologists wrong about? Today is Friday and here are your links!
A short week full of Christmas events and defenses and farewells has passed here at my university, so this round-up is also to remind myself what I’ve missed… Today is Friday and here are your links!
