  • Earthquakes in Italy: first InSAR data and field reconnaissance

    On 26 October two shallow normal faulting earthquakes occurred in Central Italy, very close to the epicentre of the Amatrice Earthquake from earlier this year. The first quake reached a magnitude of M5.5 and was followed by a M6.1 just two hours later. The events caused serious damage (see here for a video and some images), but luckily only one person died as most people had left their houses after the first moderate shock. This could have turned out much worse. Apparently the quakes at least partly filled the gap between the 1997 Colfiorito events and the 2016 Amatrice Earthquake. more

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

    A lot of new papers have been published on paleoseismology, earthquake geology, active tectonics and tsunamis last month. We have research on slowly deforming regions, on the active tectonics of Mexico, New Zealand, Armenia, and Iran, new data from the Kumamoto earthquake, plus some marine/coastal paleoseismology and tsunami studies. Enjoy reading!

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

    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.

  • 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.

  • 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.

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

    It’s June and it’s time for a new paper round-up, isn’t it? When I compiled the list during the past weeks I already realized that there’s a lot of new literature out there, and I guess this month’s post is probably the longest list we’ve ever had – 21 articles! So here are the latest papers on paleoseismology, tsunamis (maaaany tsunami papers this time), and active tectonics. As always: Any suggestions are highly appreciated. Enjoy reading!

  • 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!

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

    This is the April edition of my paper round-up. Today I recommend papers on high-resolution topography data, fault mechanics, earthquake environmental/archaeological effects (liquefaction, rotated objects, landslides), Quaternary dating, a fault database for Asia, and tectonics of New Zealand and Martinique. Enjoy! more

  • Guest blog by Sascha Schneiderwind (RWTH Aachen University): Multiparametric trenching investigations

    [Update 15 February 2017: Since Sascha is an author here now, the post was attributed to him.]
    Greece is one of the main targets of RWTH Aachen’s Neotectonics & Geohazards group. They worked on paleo-tsunamis, active faults on the Peloponnese, in Attica, and on Crete, and on the application of terrestrial LiDAR and shallow geophysics for active tectonics research. In their latest paper, Sascha Schneiderwind et al. developed a methodology to aid paleoseismic trenching studies. They use t-LiDAR and georadar to better and more objectively characterise lithological units. His paper includes nice examples from Crete and from the famous Kaparelli Fault. Here is his guest blog: more
