Report on the coseismic effects of the 24 August 2016 Amatrice Earthquake

The EMERGEO Working Group has conducted extensive field work after the 24 August 2016 Amatrice Earthquake in Italy and put together a report on the coseismic effects. The report is in English and can be downloaded from the INGV earthquake Blog here: PDF (6.1 mb)

The report includes data on environmental earthquake effects like surface ruptures, fractures, landslides, and rockfalls. More than 2400 data points have been collected.

Video: Special Session on the Amatrice Earthquake at the 88º Congresso della Società Geologica Italiana, Naples, 7 September 2016

A special session on the Amatrice Earthquake of 24 August in Italy was held at the Congress of the Geological Society of Italy (Naples, 7 September, 2016). A video of the entire session is now available online. Although the talks are in Italian, it is easy to understand and the slides tell the story.

New papers on paleoseismology and active tectonics (August 2016)

It’s a busy summer for me with lots of field work going on, but there’s still time to read the latest papers on paleoseismology and earthquake geology. Here’s my latest paper round-up. No tsunami papers this time, I am sorry. Enjoy reading and as always, please don’t hesitate to tell me which papers I have missed.

Guest blog by Javier Escartín (IPGP) & Frédérique Leclerc (EOS): Studying coseismic deformation along submarine faults

The geometry, length, and displacement of fault ruptures that breach the surface provide critical information on the behavior of faults during seismic events (coseismic deformation), and on their long-term behavior. The study of coseismic fault ruptures has concentrated almost exclusively along continental faults, while submarine studies have been scarce, and only a few provided quantitative constraints in parameters such as fault displacement (e.g., Tohoku Earthquake). In addition to represent more than two thirds of the Earth’s seismicity, submarine faults can also be associated with tsunamis, potentially increasing the seismic hazard that these structures pose.

New papers on paleoseismology, tsunami, and active tectonics (July 2016)

Today’s paper round-up is rather short. Maybe this is due to the start of the field work season and many editors being involved in field research, maybe it’s just holiday season. Maybe I’ve missed some papers because I have been in the field, too. However, there are some very interesting studies, especially concerning tsunamis. Enjoy reading and please tell me what I’ve missed in the comments.

Classification of earthquake-induced landslide event sizes

 

Some weeks ago we published a new study on the classification of earthquake-induced landslide event sizes based on seismotectonic, topographic, climatic and geologic factors. Our idea was that this classification could be used to help improve seismic hazard assessment by contributing to a better prediction of landslide hazards induced by an earthquake when the geologic, topographic and climatic context is well defined. Possible applications could be the short-term prediction right after an earthquake or scenario modeling, e.g. for critical infrastructure. Since earthquake triggered landslide event sizes are also an important proxy for the estimation of magnitude and intensity of past earthquakes, I thought our study might be interesting for the paleoseismicity community as well, and so I put together a brief summary.

New papers on paleoseismology in the Tien Shan

Between 1885 and 1938, the northern Tien Shan at the border between present Kyrgyzstan and Kazakhstan experienced a remarkable series of five major earthquakes, exceeding M6.9 and reaching up to M ~ 8 (1885 Belovodskoe M6.9, 1887 Verny M7.3, 1889 Chilik M~8, 1911 Chon Kemin M8, and 1938 Kemino Chu M6.9). Combined, the seismic moments add up to almost moment magnitude 9, which is a significant amount of strain released in roughly 50 years and across an E-W stretch of less than 500 kilometers. Even more intriguing is the fact that the ruptured region is located more than thousand km north of the nearest plate boundary and associated India-Eurasia collision zone. The macroseismic areas of these earthquakes include the present-day capital of Kyrgyzstan, Bishkek (Frunze) and the former capital and still largest city of Kazakhstan, Almaty (earlier names Alma Ata and Verny).

New papers on paleoseismology, tsunami, and active tectonics (May 2016)

Today’s paper round-up covers a very wide spectrum of earthquake related studies. We have work on tsunamis, turbidites, and lake paleoseismology, paleoseismological data from Asia, Archaeoseismology, mud volcanoes, the ESI-2007 scale, and an explanation on what the rise of the Andes is driven by. Enjoy reading!
