Lead by ISPRA, scientists from Italy, UK, and Norway have conducted field surveys and remote sensing to analyse the earthquake environmental effects of the 24 August, 2016, Amatrice Earthquake. The team has produced a 31-pages report that covers mainly field work results and INSAR data on ground deformation. Great photos of the surface ruptures! more

Today’s paper round-up has lots of tsunami papers, including one on the use of DNA to decipher paleo-tsunami deposits. Also, we have some papers about Italy, even from the area of the 24 August Amatrice earthquake. Enjoy reading and please don’t hesitate to tell me which papers I’ve missed.
Tomorrow, 18th June 2015, we – many voluntary student helpers and staff from RWTH Aachen University and the Geoverbund ABC-J are organizing with the Einhard-Gymnasium in Aachen, with 11-14 year old pupils the FIRST German Shake Out around midday. In special lectures and lab courses we have prepared the scholars for this event, but WHAT?? is a ShakeOut?
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
Annals of Geomorphology has now published a new volume on Paleotsunamis in its Supplementary Issues. Issue 57 (4) is all about Reconstructing and modeling palaeotsunami events by multi-proxy geoscientific analyses. The volume is an outcome of the 2011 Corinth conference and edited by Andreas Vött, Klaus Reicherter and Ioannis Papanikolaou. I especially like it not only because I’ve organized the conference, but also because I am familiar with some of the study sites. Finally, I am co-author of the last paper. more
If you are looking for a last minute Christmas present, these shoes might not be the right choice. Also, I am not exactly sure if it’s too nerdy, but the idea is great and the shoes are beautiful. Think about customized shoes with the geological map of your home area… more

Outstanding exposures, new data, and novel hypotheses developed during the last decade have turned the frontal deformation zone of the Andes between 31°S and 33°S (Fig. 1) into one of the most promising areas worldwide for improving the understanding on mountain building processes and seismic hazards related to thrust tectonics.
Because the Andes are relatively narrow in these latitudes, the geodetic signal in the backarc is dominated by the subduction zone locking process at the Chile trench. Nonetheless the geodetic analysis provides some useful constraints on the location and rates of modern backarc shortening, though not necessarily on the vergence. It is currently understood that backarc shortening occurs at rates of ~4-5mm/yr over a zone that is ~30km wide (across-strike) (Brooks et al., 2003; Kendrick et al., 2006). In the north (31°- 32°10° S) this would imply that the west-vergent, Eastern Precordilleran structures are the most likely to be active, while south of 32°10° S the east-vergent structures in the Southern Precordillera belt are likely to be most active (Fig. 1).
The RealClimate blog network published two long articles on the state of the art of sea level rise estimations. Part 1 was written by Stefan Rahmstorf on 9 Jan, part 2 was posted today. What will we need to prepare for until the end of the century? more
Buenos dias! This is an update from the last day of presentations, tomorrow there will be a field excursion to the Patzcuaro area (1858 eq event). Unfortunately Christoph and I cannot join the field trip, because we booked already our flights for Friday. But we will keep you informed. Are you wondering what the title photo is?
