This month we have many case studies from all around the world, including classical paleoseismology, historical data, and tectonic geomorphology. But there are also studies more leaning towards the methodological side of our discipline, and who would have thought that an entire new type of fault systems was just discovered? Enjoy reading!
moreThe Motagua Fault in Guatemala is part of the North American – Caribbean plate boundary. It ruptured in a M7.5 earthquake in 1976, killing 23,000 people and causing ca. 230 km of surface ruptures. Very little was known, however, about previous strong earthquakes on this fault. In a new study, we identify five surface-rupturing events in the last 1300 years, including the 1976 quake. We opened a paleoseismological trench and compared our results with archaeological information from nearby sites and historical earthquake data.
moreThe 13th International INQUA Meeting on Paleoseismology, Active Tectonics and Archaeoseismology (PATA Days) was held from 2-5 February, 2026, in Antigua Guatemala. We commemorated the catastrophic M7.5 earthquake of 4 February, 1976. A pre-meeting field trip from 30 Jan – 1 Feb took the participants to several paleoseismological and archaeoseismological sites along the Motagua Fault, the plate boundary between the North American and Caribbean Plates. After the meeting, another field trip focussed on the neotectonics of the triple junction west of Guatemala City. 16 ECRs and DCRs were supported with INQUA travel grants organized by TERPRO’s project CHAMP. Here’s a short summary about the field trips and the meeting.
moreA new month, a new list. Those who attended the PATA Days in Guatemala (a report will follow!) will recognise the first three papers. There is a lot more interesting science to read this time. Enjoy and let us know if we’ve missed something. Oh – and many thanks to all of you who send links to their papers once published.

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!
