  • New papers on paleoseismology (Jan 2016)

    Plenty of paleoseismology papers have been published in late 2015 and early 2016 already! Especially those on the Gorkha earthquake made it to the news (Science and NatureGeoscience), but there is much more to discover. Check them out and – as always – tell us what we’ve missed. more

  • 7th PATA Days, Crestone, CO, 30 May – 03 June, 2016

    Dear friends and colleagues,

    The 7th International Workshop on Paleoseismology, Active Tectonics, and Archaeoseismology (PATA Days) will be held in the USA from 30 May – 03 June, 2016. The workshop is sponsored by the INQUA-TERPRO Commission and mainly organized by James McCalpin. The workshop includes several excursions and we welcome presentations on a broad list of topics related to seismic hazards and active tectonics: more

  • Guest blog: “Photogrammetry for Paleoseismic Trenching” by Nadine Reitman (USGS)

    A few weeks ago, Nadine Reitman (USGS) published an interesting paper about the use of Photogrammetry for Paleoseismic Trenching in BSSA. In this guest blog she shares her key findings and explains how to minimise errors without spending too much time measuring control points. Thanks Nadine!

    Structure-from-motion (SfM) is now routinely used to construct orthophotos and high-resolution, 3D topographic models of geologic field sites. Here, we turn SfM on its side and use it to construct photomosaics and 3D models of paleoseismic trench exposures. Our results include a workflow for the semi-automated creation of seamless, high resolution photomosaics designed for rapid implementation in a field setting and a new error analysis of SfM models. more

  • Paleoseismology & Tsunami papers – Christmas edition

    This is this year’s last issue of my paper round-up, and it includes some pretty interesting stuff. Our Greek colleagues published a report on the liquefaction caused by the 2014 Lefkada earthquakes, just in time with the recent earthquake that hit more or less the same area again (Papathanassiou et al., and see earlier posts here). Long et al. published a paper on iceberg-induced tsunamis, found in the sedimentary record – that’s a great story, isn’t it? Jacobson’s PhD on the Lake Heron Fault (NZ) is an interesting read, and Iván Sunyol’s paper on paleoseismological trenches in Mexico is especially interesting for those who attended the 2012 Morelia meeting. Zhou et al. come up with a great dataset of Pléiades imagery from the El Mayor-Cucapah Quake, Calais et al. have a close look on the northeastern Caribbean, and finally, Kufner et al.’s paper is about the collision between India and Asia deep below the Pamir and Hindu Kush.

    Enjoy reading and Merry Christmas!

  • New papers to read during the holidays

    A couple of interesting papers were published since my last round-up, including work on paleoseismology, tsunamis, measuring offsets, and boulder transport by storms. Enjoy reading! more

  • New Paper: Paleoseismology & active tectonics in Greece, and how seismic hazard zonation fails

    We published a new study dealing with paleoseismological work on the Milesi Fault near Athens, Greece. A slip rate was estimated based on GIS work, mapping, and trenching. Four surface-rupturing earthquakes in the last 4-6 ka were found, and we estimate magnitudes of around M6.2. With these input parameters, we developed a seismic hazard scenario that also takes into account site effects. Our results show that the official seismic hazard zonation in Greece, which is based on instrumental and historical records, contradicts geological data. We also show that extension in this region is not only confined to the Southern Evoikos Gulf graben system, but a significant amount of extension is accommodated by active faults closer to Athens. more

  • Paleoseismology, active tectonics, archaeoseismology, tsunamis: New papers you might want to read

    Here is my latest update on paleoseismology-related literature. Plenty of new hot stuff has been published, today we have: archaeoseismology & liquefaction in Corinth, incredibly good data from the Gorkha earthqukae (Nepal), an earthquake that deviated the Po River, paleotsunamis in Israel and Taiwan, notes about tsunami boulders, and tsunamis in Greece. Enjoy!

  • Stuff to read: New literature on paleoseismology and active tectonics

    Is it just me or is the frequency of papers being published increasing…? Anyway, here’s the literature update with studies on paleoseismology and active tectonics. Today we have: Faulting in the Canyonlands, seismites from the Jurassic, a fake earthquake in Cologne, dynamic triggering, news from the San Jacinto Fault, ground motion variation between repeating earthquakes, metrics to evaluate seismic hazard maps, submarine tectonic geomorphology, the 1897 Great Assam Earthquake, and a collection of papers on geophysical imaging and interpretation of outcrops. Enjoy!

  • Latest papers on paleoseismology, active tectonics, archaeoseismology, and tsunamis

    In case you need a good read for your summer holidays, here are the latest papers on paleoseismology and related fields. Today including a IAEA TecDoc about paleoseismology, an early paper on the Gorkha quake, coral paleoseismology, some tectonic geomorphology in Spain, clastic dykes, and tectonic uplift of an island in Chile. Enjoy!

  • An update on paleoseismology literature

    Here are my latest updates on papers and books that deal with paleoseismology, active tectonics, tsunamis and similar topics. There is a good portion of lake/turbidite paleoseismology with some beautiful seismites. We also have some more general tectonics/review papers, and an interesting attempt to establish a global fault database. Plus, there is an intense ongoing discussion about Kashmir and news from Napa. Enjoy!
