Shaky Ground is the new novel in Sharon Kae Reamers Schattenreich series. You’ve probably read Primary Fault, so you’re familiar with seismologist Caitlin and her adventures in Cologne. In this case, you will probably head towards your local book store now or you might be happy to find this Amazon link. If not, check out the story about science, fantasy, and the Cologne “Klüngel” and tell us how you liked it in the comment section! You might know the author not only from her novel, but also from her science... more
Dear friends and colleagues,
the registration for the PATA-Days is now online at pata-days.org. We used the acronym now to avoid the long title (4th International INQUA Meeting on Paleoseismology, Active Tectonics and Archeoseismology, 9-15 October, Aachen, Germany) and to do a favour to our Spanish friends…
Please find all information at the new website, including the abstract template.
The deadline for registration and abstract submission is 15 July.

Imagine 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.

Today we went for field work again – mapping active faults in Northern Attica, trying to find out about offsets and slip rates, and scouting sites for applying Ground Penetrating Radar (GPR) later. We found some very beautiful fault scarps and measured a good number of strike and dip values. At two locations we also recorded topographic profiles across the scarps in order to get an idea about the vertical offset. Combined with the assumption that these scarps are post-glacial, we can estimate slip rates. more
I am currently in Greece for field work on faults in the vicinity of Athens. Sascha from RWTH Aachen University is doing his MSc. thesis on remote sensing, geophysical analyses, and mapping of some structures that we think could be active, and me and Ioannis are with him in the field for the first few days. Right on the first day we found some promising outcrops which we will map and check in detail during the next days. more
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
Last 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
A shallow (12 km) earthquake of magnitude ML3.0 occurred this morning in W Germany near Koblenz in Ochtendung. According to the Geological Survey of Baden Württemberg, the magnitude was ML2.6 only, but the quake was preceded by few minor events (M<2.0) on 9 April and 14 April. Local news (The Rhein Zeitung) report that some people felt the event and that birds were afraid. This earthquake didn’t cause any damage, but it’s interesting in another way: Its epicentre is only 8 km away from the former nuclear power plant (NPP) Mülheim-Kärlich. more
A very strong earthquake occurred in Eastern Iran close to the Iran-Pakistan border. USGS reports a magnitude of 7.8 and a shallow depth of 15 km, EMSC data suggest M7.7 and 50 km depth. Preliminary shake maps estimate intensities around MSK VIII, which would be enough to make traditional adobe buildings to collapse. Reports confirm the event was felt as far away as Muscat, Oman (600 km distance!). Update: USGS now also reports a depth of 80 km.

Today at 11:52:50 UTC a magnitude 6.3 earthquake occurred in SW Iran close to the shore in a depth of 10 km. The event was widely felt in Iran and across the NE Arabian Peninsula. Moment tensor solution reveal a thrust mechanism, which is in perfect concordance with the historic seismicity pattern. The event was caused by the convergence of the Arabian and Eurasian plates, that not only built up the impressive Zagros Mountains, but also lead to the formation of the Makran Subduction Zone. Relative plate motions there are as fast as 20 mm/yr in the central part. more
