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:
moreThe 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.

This time we have an impressive variety of earthquake study sites: Turkey, China, USA, Tadjik Basin, Italy, Japan, Sumatra, Himalayas, Spain, Mexico, Balkans, Mars, laboratory. Who could possibly ask for more? Plus some interesting work on fault physics. Check out the latest papers on earthquakes, active tectonics, and paleoseismicity:
On 12 June, 2017, an earthquake with a magnitude of Mw6.3 occurred south of the island of Lesvos in Greece, damaged hundreds of buildings and claimed one life. The event ruptured a NW-SE trending normal fault and had a focal depth of 13 km. Our colleagues from the National and Kapodistrian University of Athens mapped the earthquake damage and the environmental effects that accompanied the earthquake. They found mass movements, secondary cracks, and report on a small tsunami. Their report can be downloaded here (PDF, 6 mb). For a higher-resolution file (33 mb), follow this link. Many thanks to Efthymios Lekkas for sending the report. more

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!
