  • EEEs of today’s Mw6.5 earthquake in Greece

    A shallow Mw6.5 earthquake hit western Greece today in the morning. The quake had a right-lateral strike-slip mechanism and occurred at the Cephalonia transform, offshore Levkada. Two people died and some damage to buildings was reported. The event caused environmental earthquake effects (EEEs), namely widespread rockfalls that produced an amazing dust cloud. The blog North Ithaca has some great pictures of collapsed walls, damage to buildings and the dust cloud.

  • Paleoseismological field work in Kyrgyzstan

    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. more

  • Symposium on Mega Earthquake Induced Geo-disasters – The field trips part II: Qipan gully debris flow

    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! more
