The latest issue (May 2013) of the Bulletin of the Seismological Society of America (BSSA) is dedicated to the Tohoku Earthquake and Tsunami of March 2011. The studies published therein deal with the source models of the megaquake and rupture dynamics, the ground motions, the tsunami propagation, earthquake triggered landslides and induced seismicity, earthquake environmental effects, and one paper presents a new proposal for an extended Tsunami Intensity scale. Especially the last topic is very interesting and I guess we’ll soon see if this approach makes it as a standard scale. I am not sure at the moment how good the scale works on a global scale, more data is needed to find out about its strengths and weaknesses. However, the old 6 grade Sieberg-Ambraseys intensity scale had some problems and it’s good to try something new. I wonder how it compares to the already 12-graded Papadopoulos and Imamura scale.
A new issue of SRL has also been published, and there are some nice articles on seismic hazard assessment. Also, the studies on the effects of the recent Virginia earthquake on a nearby nuclear power plant are interesting.
