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
2014-02-16 | 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

Two M6+ earthquakes in Kefalonia (Greece) within 8 days
2014-02-03 | in Earthquake | 4 responsesTwo earthquakes of magnitude M6+ occured near the island of Kefalonia in Western Greece on 26 January and 3 February, 2014. Both were shallow strike slip events that are associated with the Kefalonia transform fault and caused not only damages to buildings and infrastructure, but also significant earthquake environmental effects (EEEs). Here I compile some photo and video sources from rockfalls and other features. more

New paleoseismology papers
2014-01-26 | in PaperBesides the two special issues on tsunamis and paleoearthquakes that I’ve already blogged about, some more interesting papers on paleoseismology have recently been published. They deal with paleoseismology of the North Anatolian Fault, with tectonic geomorphology of S Spain, and with the ESI scale applied on a quake in Kashmir. more

The Iberfault 2014 meeting – 2nd Iberian meeting on Active Faults and Paleoseismology, 22-24 October, Lorca, Spain
2014-01-22 | in MeetingAfter the 1st Iberfault meeting in 2010, the 2nd meeting will take place in Lorca, Spain from 22-24 October, 2014. Any research on active tectonics and paleoseismology in Iberia is welcome, a special focus will be set on the QUAFI database. The conference will be organized by José Martinez Díaz (UCM), Eulàlia Masana (UB) and Miguel A. Rodríguez (IGME). Lorca became famous in 2011 when a shallow MW5.1 earthquake killed 9 people and caused severe damages in the city (there is an ongoing discussion whether or not groundwater lowering for irrigation during the last decades has caused, triggered, or influenced the quake).

Special Issue “Geology and Archaeology of Earthquakes” in Cuaternario y Geomorfología
2014-01-21 | 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?
2013-12-08 | 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

Report on the Mw7.1 Bohol, Philippines earthquake of 15 October 2013 by Stéphane Baize (IRSN)
2013-10-31 | 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
2013-09-18 | 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

Earthquakes and dust clouds
2013-02-25 | 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
