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.

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!

ISPRA volume “Earthquake Environmental Effect for seismic hazard assessment: the ESI intensity scale and the EEE Catalogue”

Earthquake Environmental Effects (EEE) have proven to be valuable for describing past earthquakes and their geological imprints. The ESI2007 is a relatively new intensity scale dedicated to such effects, but also integrating traditional macroseismic scales. Examples of ESI2007 intensities assigned to large earthquakes are being collected in the EEE web catalogue hosted by the ISPRA and ESI2007-related work is conducted in the framework of INQUA.

Another milestone now has been achieved with the ISPRA volume “Earthquake Environmental Effect for seismic hazard assessment: the ESI intensity scale and the EEE Catalogue”. This book is now available online here. It contains updates on the ESI2007, examples of applications, documentation of the EEE Android App, a huge reference list and, most importantly, the ESI2007 description in ten languages: Continue reading “ISPRA volume “Earthquake Environmental Effect for seismic hazard assessment: the ESI intensity scale and the EEE Catalogue””

Guest blog by Elisa Kagan: New book on the Dead Sea Transform

A new book on the Dead Sea Transform has been published by Springer:

DEAD SEA TRANSFORM FAULT SYSTEM: REVIEWS

Together with Prof. Zvi Garfunkel and Prof. Zvi Ben-Avraham, I am a co-editor of this book. The book focuses on various aspects of the fault system, from geophysics, to tectonics, paleolimnology, hydrology, seismicity, and PALEOSEISMICITY. Most relevant to this blog are the papers by Agnon and by Marco & Klinger.

  • Shmulik Marco and Yann Klinger review in a new light the on-fault paleoseismic studies carried out along the DST.
  • Amotz Agnon delves into the off-fault seismite archives (lake, cave).

Here is a link to the book on the Springer site: http://link.springer.com/book/10.1007%2F978-94-017-8872-4
