The latest issue (May 2013) of the Bulletin of the Seismological Society of America (BSSA) is dedicated to the Tohoku Earthquake and Tsunami of March 2011. The studies published therein deal with the source models of the megaquake and rupture dynamics, the ground motions, the tsunami propagation, earthquake triggered landslides and induced seismicity, earthquake environmental effects, and one paper presents a new proposal for an extended Tsunami Intensity scale. more

Kind of surprising M4.5 earthquake in NE Hungary
2013-04-23 | in Earthquake | one responseLast night (22:29 UTC on 22 April) a M4.5 earthquake rattled NE Hungary. The event was shallow (~10 km) and the epicentre was only about 25 km south of the city of Eger, famous for its red wine (Egri bikavér). The area is south to the Inner Western Carpathian Mountains. Light damage has been reported from the epicentral area, the EMSC questionnaires document intensities of VI. more

Paleoseismological papers in the BSSA April 2013 issue
2013-03-22 | in PaperBSSA’s most recent issue is full of paleoseismological work. The April 2013 issue contains a number of papers dealing with old earthquakes in Turkey, California, Argentina, and Jamaica. Also, there’s info on earthquake catalogues in South America and China. A study on seismic sources in the Lower Rhine Embayment, (W Germany, Belgium, The Netherlands) is especially interesting for me, because it’s right in my backyard. Plus, there are some basic studies on the reliability of paleoseismological investigation and problems in earthquake geology. more

Has Roger Bilham been deported from India because of his seismic hazard warnings?
A new story came up recently that sounds like the L’Aquila case, but the other way round. Dr. Roger Bilham from the University of Colorado, a well-known earthquake researcher, was denied entry to India earlier this year. He was on a flight to Bhutan and supposed to change planes in New Delhi when Indian officials sent him back to the plane he just arrived on. Officially, he was accused with having the wrong type of visa. Himself and many colleagues, however, are sure that he was deported because he stated that the seismic hazard in India is underestimated. more

New paper on active faulting in Greece
2012-12-12 | in PaperA new paper was just published on Active faulting in the north-eastern Aegean Sea Islands. Our colleague Alex Chatzipetros and his co-authors investigated the distribution of seismicity and faulting pattern at the islands of Lemnos, Aghios Efstratios, Lesvos, Chios, Samos and Ikaria. From this data and field analyses they concluded on the effects of active faulting on the local geomorphology. more

What’s up? The Friday links (49)
2012-12-07 | in The Friday Links | one responseA strong earthquake rattled Japan today and caused some intense shaking in the Fukushima region. The quake had a magnitude of 7.3 and occurred at a depth of ~30 km. A tsunami warning was issued immediately, but until now (11:30 CET) it looks like no waves were created. more

New paper on the archaeoseismology of Athens
2012-11-15 | in PaperA new paper on the archaeoseismology of Athens, Greece, was published in the Bulletin of Earthquake Engineering by AMraseys and Psycharis. The authors investigated two classical columns at the Akropolis which survived since classical times and modelled the behaviour of the structures under dynamic (seismic) load. They explain observed damages at the columns and also estimate maximum ground movement that would have toppled the columns. It looks like Old Athens has been relatively lucky in terms of earthquakes in the past, despite it is surrounded by active faults… more
