On 15 October, 2013 a shallow Mw7.1 earthquake occured in Bohol, Philippines. The quake caused more than 200 fatalities and severe damages. Instrumental intensities of VIII – IX were recorded and the USGS estimates the maximum slip to be around 120 cm. Stéphane Baize from the French IRSN created a report not only on the seismological and tectonic background of the earthquake, but also on the earthquake environmental effects (EEEs) that were caused by the event. more

thank you very much for making the PATA Days 2013 such a great event! I hope you all had a safe trip back home or some more nice days with better weather. The abstract volume of the PATA Days is now available online. Currently, you can only download the entire volume, we will upload the single files into a sub-directory later.

Farming community killed by earthquake-related mudflows in China c. 4000 years ago
2013-10-17 | in PaperRecent archaeoseismological studies have provided us with spectacular examples of skeletons as earthquake archaeological effects. Cases include the Neolithic skeletons of Tell es-Sultan, ancient Jericho (one of them beheaded by a fracture crossing the site!) published by Alfonsi et al. in SRL (2012) and the skeletons smashed by building collapse reported by Berberian et al. in JAS (2012).
To this list should now be added the case of Lajia (Guanting Basin, central China), where a team of Chinese researchers uncovered a series of skeletons buried under a thick layer of clay interpreted as the result of an enormous, earthquake-related mudflow c. 3950 cal BP. more

An earthquake series in Romania
2013-10-06 | in EarthquakeA fascinating series of relatively shallow minor earthquakes is currently occuring in Romania in the Galaţi area. Around 40 events occured during the last few days, most of them with magnitudes of ~3. Now a mb5.4 earthquake happened in more than 100 km depth. The quake was felt in wide parts of Romania and Bulgaria. Due to its depth no damages are expected. First moment tensor solutions do not give a clear picture yet, but it seems like NE-SW trending thrust event could have happened at the SE bend of the Carpatian Mountains. more

Earthquake in Pakistan – lessons to learn
2013-10-04 | in Earthquake, OpinionAfter the strong earthquake in Pakistan a good part of the media coverage was about the fascinating story of the new island that emerged off Gwadar. While this was really amazing I think now it’s time to think about the consequences of the quake itself. We have seen a shallow M7.7 event that produced severe shaking across a large area. Peak ground acceleration exceeded 1 g in the 0.3 s period and was still intense in longer periods. 515 people have reportedly been killed and more than 100,000 are homeless. more
