This year’s EGU will be held from 19-30 April. It will be another virtual conference, which is why it’s named vEGU21. Anyway, there are many interesting sessions, and a couple of them could be very interesting for paleoseismologists, earthquake geologists, and active tectonics aficionados. For example, EDITH is also a project of INQUA‘s TERPRO commission.
Some colleagues told me that 2020 was the most productive year they ever had – without the distraction of field work and meetings they managed to write up a lot of things they’ve had on their desks. Others reported exactly the opposite. In any case, I hope that this year life will go back to normal and I wish you a wonderful 2021. Here are the latest papers, quite a good start into the next decade. Stay safe!
On 18 December we held a short virtual PATA meeting, since the in-person meeting to be held in Chile had to be postponed to 2021. The PATA Days (Paleoseismology, Active Tectonics, Archaeoseismology) are the main event of INQUA TERPRO‘s earthquake science community, led by the project TPPT (Terrestrial Processes Perturbed by Tectonics). Most of us are starving for joint field trips and personal contacts, but it was nice to at least see everyone online – more than 170 people attended the 1.5 hrs event. The five main topics were:
The 2nd edition of “Tsunamiites – Features and Implications” has just been published by Elsevier. It collects 21 chapters on the sedimentology of tsunamis, written by a team of international scientists. The new edition (1st edition was published in 2008) also includes lessons learned from recent events such as the 2011 Tōhoku earthquake and tsunami. The 482-pages book was edited by Tsunemasa Shiki, Yoshinobu Tsuji, Teiji Yamazaki, and Futoshi Nanayama.
This is the first attempt to apply a computational fluid dynamic modeling-based quantitative “fossil seismograph” to develop a large earthquake record.
The record is calibrated to historic earthquakes, for which the Dead Sea area has a famously long span, and it confirms a clustered earthquake recurrence pattern and a group-fault temporal clustering model.
The record yields much shorter mean recurrence for large (≤ 1.4 kyr vs. 7-11 kyr) and moderate (≤ 500 yr vs. 1600 yr) earthquakes than previously obtained, thus reveals a much higher seismic hazard than previously appreciated on this slow-slipping plate boundary.
This year was truly a roller coaster ride! A large part of the world is still battling Covid-19; meetings, conferences, and workshops are held online, and teaching has also changed a lot. December is usually crowded with deadlines and (virtual) AGU, but I hope you find some time to check out the latest papers on earthquakes, paleoseismology, and active tectonics. We have a great list of papers, this time with exciting news from Italy, New Zealand and the Dead Sea, a lot of historical seismicity studies, and many contributions on Asian tectonics. Stay safe & happy researching!
To increase the visibility of activities of Paleoseismicity.org to Chinese in China and around the world and to promote potential interactions with Chinese, I opened an account for Paleoseismicity.org on the WeChat platform last week. The account was named “古地震”. (“古地震” means “paleoseismicity” in English).
Paleoseismicity.org is a page dedicated to scientists and everyone else interested in paleoseismology, archeoseismology, neotectonics, earthquake archeology, earthquake engineering and related topics. Different authors irregularly write about recent papers, field work, problems, conferences or just interesting things that they come across. We intend to provide a platform for discussion and scientific exchange. Interested in joining as an author? Please contact us!
