On 23 June, 2020, a magnitude 7.4 subduction earthquake struck western Mexico and let the earthquake early warning sirens sound in the capital. Reportedly, ten people lost their lives and thousands of houses were damaged in Oaxaca. Our colleagues Magda Velázquez-Bucio, Sabina Porfido, and Alessandro Michetti have put together a report on the Earthquake Environmental Effects of this event in English and Spanish:
moreNormal life has come to a halt, but publishing papers apparently not. Here’s a lot of stuff to read at home: nice remote sensing studies, very cool field observations (good old days), an entire trilogy by Dirk Scherler and Wolfgang Schwanghart on drainage divides, and much more. Enjoy reading, tell me if I’ve missed something, and stay safe.
moreSince we are all (?) sitting at home and waiting for the situation to improve, this may be a good chance to catch up with the latest literature. Alas, new papers are published without mercy every month, and March was no different. Here are the latest ones on paleoseismology., active tectonics, and large earthquakes. Stay safe!

“The beaches in Oman are pristine.” What sounds like an introductory sentence to a tourist brochure has scientific significance. Natural conditions without anthropogenic overprint are characteristic for vast stretches along the 1700 km coastline of Oman from the Strait of Hormuz in the north to the border of Yemen in the south. This situation allows geological research addressing Quaternary sea-level change on various timescales spanning from minutes to millennia. Over the last couple of years, we carried out research funded by the Omani Government and the German Research Foundation (DFG). Our findings are currently published in a series of papers (Schneider et al. 2018; Ermertz et al. 2019; Falkenroth et al. 2019, subm.; Hoffmann et al. 2020a, b) and are briefly summarised here.
moreToday we have a number of studies on “classic” paleoseismology, but also a fair share of tsunami and historical seismicity/archaeoseismology research. Plus, some very interesting papers on methods and concepts. Not to forget the first one in the list that presents an extremely useful surface rupture database. I may write a long blog post on this one, soon. Enjoy reading!
moreThe deadline for the submission of abstracts to the 34th IAS Congress of Rome 2019 is approaching (30 March 2019). The 34th IAS meeting will be held in Rome from 10-13th September 2019 (http://iasroma2019.org/).
There will be lots of interesting sessions, of special interest for the earthquake geology community will be session 7.11 The Sedimentary Record of Earthquakes, Tsunamis and other Extreme/Catastrophic Events.
Conveners:
The 34th IAS meeting on sedimentology will take place in Rome from 10-13 September, 2019. There are several sessions that are of interest to the paleoseismology community, and session 7.11 is especially devoted to past earthquakes:
Massimo Moretti (Bari University, Italy); Jasper Knight (Wits University, South Africa); Giuseppe Mastronuzzi (University of Bari Aldo Moro, Italy); Andreas Vött (Mainz University, Germany).
Extreme/catastrophic events are by definition rare and episodic, but they have occurred frequently throughout Earth’s history. High magnitude events such as earthquakes, tsunamis, large-scale landslides, extreme floods and storms, extraterrestrial impacts, etc. often leave a sedimentary imprint in the geological record. Nevertheless, recognition of extreme event traces in sedimentary successions is often difficult and may be ambiguous.
This session is focused on examples of seismites, tsunamites, and other sedimentary deposits that have been formed by extreme events. We encourage contributions including field-based examples discussing different approaches on data analysis and interpretation of these deposits. We also welcome studies on analogical modelling and numerical simulation for relationships between triggering processes and products of extreme events.
Deadline for early bird registration is 30 May 2019, abstract submission closes on 30 March.

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!
