The Earthquake Geosurvey App by George Papathanassiou and Vasilis Kopsachilis has reached 500 downloads – congratulations! The App allows mapping earthquake environmental effects in post-earthquake surveys and is currently available for Android. An iOS version will come soon. Find more information about the app here at the official homepage or visit Google Play for download. more

A team of geologists mapped the earthquake environmental effects (EEEs) of the two M6+ events that occurred at the Greek Island of Cephalonia on 26 January and 3 February, 2014. G. Papathanassiou, A. Ganas, S. Valkaniotis, M. Papanikolaou and S. Pavlides participated in these field campaigns. George Papathanassiou sent me the preliminary report today. The team found widespread evidence for “liquefaction, road-fill failures, rock falls, small landslides and stonewall failures“. more

On 27 March, 1964, an earthquake of magnitude 9.2 occurred offshore Alaska (Plafker, 1965) and caused a Pacific-wide tsunami. This quake was the second most powerful that was ever recorded and is also referred to as the Great Alaska Earthquake. The USGS has now released a report on a comparable tsunami scenario. The SAFRR (Science Application for Risk Reduction) Tsunami Scenario deals with a tsunami caused by a major quake off Alaska and investigates the possible impact at the coast of California.  more

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

A colleague sent us this image which he took in the Athens subway few days ago. He didn’t know the person who was carrying the luggage, but he recognized the sticker on the suitcase.

I also do not know who you are, but I like your suitcase! more

On 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 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

My latest paper deals with the Holocene activity of the Ventas de Zafarraya Fault in Southern Spain. It was published some days ago in the most recent issue of Cuaternario y Geomorfología. The Ventas de Zafarraya Fault (VZF) west of the Granada basin (36.96° N, 4.14°W) has a beautiful morphologic expression and an exciting history. The fault bounds the Zafarraya polje to the south, with Quaternary sediments to the north (hanging wall) and limestones of the Internal Subbetics in the footwall (Fig. 1). more

Besides 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

After the 1^st Iberfault meeting in 2010, the 2^nd 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 M_W5.1 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).
