The latest issue of Annals of Geophysics is devoted to Earthquake geology: science, society and critical facilities. Vol 56 (6) is a Special Volume, and I am proud to say it’s our volume! Finally, 14 papers are included in this issue, most of them authored by early career researchers (ECRs). The papers are based on work presented at the 2nd INQUA meeting on Active Tectonics, Earthquake Geology, Archaeology and Engineering in Corinth, Greece, 2011. The issue was edited by Christoph Grützner, Salvatore Barba, Ioannis Papanikolaou and Raul Pérez-López and all papers are open access! more

Some photos of EEEs caused by the Cephalonia M6.0 earthquake
February 16, 2014 | in Earthquake, PaperOn 26 January and 3 February, two strong and shallow earthquakes of magnitude 6+ occured at the island of Kefalonia/Cephalonia in Western Greece. The events caused intense damage to buildings and infrastructure. A team of EERI (Earthquake Engineering Research Institute) scientists went to the island to map these kind of damages. Earthquake Environmental Effects (EEE) like rockfalls, landslides, and lateral spreading were also caused by the events. George Papathanassiou and his colleagues mapped these features and sent me the following photos from Lixouri. more

Special Issue “Geology and Archaeology of Earthquakes” in Cuaternario y Geomorfología
January 21, 2014 | in PaperA special issue on “Geology and Archaeology of Earthquakes” has currently been published in Cuaternario y Geomorfología (Quaternary and Geomoprhology, ISSN: 0214-1744), which is the official journal of the Spanish Quaternary Union (AEQUA) and the Spanish Geomorphological Society (SEG): Vol 27, No 3-4 (2013) – Geología y Arqueología de Terremotos. The issue includes an introduction and ten research papers on earthquake geology and archaeoseismology of the Iberian Peninsula. Most papers are in English, few in Spanish. more

Paleoearthquakes identified in W Nepal – seismic hazard higher than expected?
December 8, 2013 | in PaperAn interesting paper has been published in Nature Geoscience by Murphy et al.: Limit of strain partitioning in the Himalaya marked by large earthquakes in western Nepal. It doesn’t happen too often that paleoseismological papers are published in this journal and it’s also not too often that authors publish such beautiful photos. The authors identified a more than 60 km long rupture in W Nepal with 10 m of surface offset (strike-slip with a normal component). 14C dating points to seismic activity between AD 1165 and 1400. That’s pretty surprising for many reasons: more

New issue of SRL with lots of paleo- and archeoseismology papers
November 4, 2013 | in PaperThe new issue of Seismological Research Letters has been published now and it contains a lot of articles for those liking old earthquakes. Some topics might sound familiar to you when you attended the PATA days conference as the authors presented parts of their work.
I have selected a few papers that are especially interesting to the paleoseismology community. They are about the use of Google StreetView for assessing macroseismic damage (Hinzen, 2013), archeoseismology in the Levant (Alfonsi et al. 2013), Earthquake rotated objects caused by the Emilia Romana earthquake – a fascinating EAE! (Cucci and Tertoulliani, 2013), a strong historical earthquake in Italy that likely did not happen at all (Camassi and Castelli, 2013) and new data on historical earthquakes in the Himalayan (Rajendran et al, 2013). Also, I added a paper on archaeoseismological investigations in northern Sicily that was published recently in Quaternary International (Bottari et al, 2013). Spend the rainy autumn evenings with a good read!

Report on the Mw7.1 Bohol, Philippines earthquake of 15 October 2013 by Stéphane Baize (IRSN)
October 31, 2013 | in EarthquakeOn 15 October, 2013 a shallow Mw7.1 earthquake occured in Bohol, Philippines. The quake caused more than 200 fatalities and severe damages. Instrumental intensities of VIII – IX were recorded and the USGS estimates the maximum slip to be around 120 cm. Stéphane Baize from the French IRSN created a report not only on the seismological and tectonic background of the earthquake, but also on the earthquake environmental effects (EEEs) that were caused by the event. more

Earthquake-induced landslides in the Appennines – distance versus magnitude and ESI epicentral intensity
September 18, 2013 | in PaperA new paper by Esposito et al. has been published in Springer’s Landslide Science and Practice that will help to better constrain intensities on the ESI scale. Landslides induced by twelve moderate to strong earthquakes events during the last 300 yrs have been analyzed. The authors calculated distance vs. magnitude and distance vs. ESI epicentral intensity relationships, similar to the famous correlations by Keefer (1984). more

New App on Earthquake Environmental Effects (EEE) released
May 14, 2013 | in Aachen 2013 | one responseImagine you live or work in a seismically active region. Imagine you work on paleoseismology, active tectonics, earthquake engineering and encounter an earthquake. And now imagine you stand in the field examining recent earthquake effects. You soon might think about an easy way to document your data to have it digitized right away! Now you can use your Android smartphone to map, categorize, describe and report Earthquake Environmental Effects (EEE). A new application has been released: Earthquake Geo Survey.

Earthquakes and dust clouds
February 25, 2013 | in Earthquake | one responseToday’s post of the Landslide Blog about a rockfall caused by a volcanic earthquake reminds me about something that’s in my mind for years already. Could we use dust deposits as a paleoseismological archive? Dust clouds of all sizes, ranging from tiny to huge, can be associated with seismic shaking, especially in arid and mountainous regions. Here I have collected a few videos I found on YouTube. When large amounts of dust settle they should form a distinctive layer recognizable in the sedimentary record, comparable to volcanic ash deposits. Of course they will be harder to be identified, since the material is the local one. I guess this could be done, similar to turbidites in marine paleoseismology. There are papers that describe changes in the aerosol content in the atmosphere after earthquakes, so why not look for them on earth? more

Three new papers: paleotsunamis, neotectonics in Greece; ESI2007 in Slovenia
June 6, 2012 | in PaperThree papers published recently caught my eyes. First, Andrej Gosar investigated the earthquake environmental effects (EEEs) of the 12 April 1998 Mw =5.6 Krn Mountains earthquake, Slovenia. The quake measured VII-VIII on the EMS-98 scale, and Andrej found that the intensities reached the same values on the ESI2007 scale. He reports that the intensity distributions for both scales are comparable, but show some differences due to the sparsely populated epicentral area. The research concentrated on rockfalls for EEE determination. It’s a nice example that also moderate events can be characterized using the ESI2007 scale.
