An 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

Sessions paleoseismologists might like at EGU2014
2013-12-05 | in MeetingThe EGU2014 will take place from 27 April – 2 May, 2014 in Vienna, Austria. The call for abstracts is open and submission deadline is 16 January, 2014. So it’s time to start thinking about which sessions would be interesting – not only for presenting own work, but also for listening to great talks. Here’s a list of sessions that a paleoseismologist could find interesting: more

An informal meeting/workshop on paleoseismology of NW Europe in Utrecht, 9 January 2014
2013-12-02 | in MeetingPaleoseismologists from northern Central Europe are meeting regularly for discussions, usually twice a year, and the next small workshop will take place in Utrecht on 9 January, 2014. The one-day meeting is dedicated to present latest results of ongoing research on active faults in the Netherlands, Belgium, and Germany (intraplate seismicity). Participants from the Geological Survey of North Rhine-Westphalia, the VU Amsterdam, TuDelft, ULG Liége, the Royal Observatory of Belgium, TNO-GDN Utrecht and RWTH Aachen University will discuss the possibilities of joint projects and collect ideas on how to proceed with ongoing studies.

What’s up? The Friday links (59)
2013-11-22 | in The Friday LinksTyphoon Haiyan was among the strongest storms ever recorded and likely the strongest one to make landfall in historical times. This mega storm hit the Philippines with windspeeds of more than 300 km/h. It caused thousands of fatalities, widespread flooding and devastation especially in its direct path. NASA’s Terra satellite is equipped with the ASTER sensor. This sensor is perfect for producing false color images of land cover and vegetation. In this image series it becomes clear that typhoon Haiyan destroyed a significant part of the vegetation around Tacloban. more

New issue of SRL with lots of paleo- and archeoseismology papers
2013-11-04 | 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!

PATA Days 2013 – abstract volume now online
2013-10-18 | in Aachen 2013, Meeting, Paper, PATA daysDear colleagues and friends,
thank you very much for making the PATA Days 2013 such a great event! I hope you all had a safe trip back home or some more nice days with better weather. The abstract volume of the PATA Days is now available online. Currently, you can only download the entire volume, we will upload the single files into a sub-directory later.

A mud volcano as an Earthquake Environmental Effect?
2013-09-26 | in Earthquake, Opinion | 6 responsesOn 24 September a shallow M7.7 earthquake rattled Pakistan. At least 300 people died and thousands of houses, most of them adobe, collapsed in Balochistan Province. The quake was felt as far away as Muscat (Oman) and New Delhi (India). Epicentral intensities reached up to IX. The earthquake appeared to be a strike slip event. Soon the media reported on an amazing effect of the quake – in roughly 400 km distance a new island appeared few hundred meters off Gwadar. more

The PATA Days conference – latest news and info
2013-09-23 | in Aachen 2013, Meeting, PATA daysDear friends and colleagues,
it’s only few days to go until the PATA Days conference will start with the icebreaker party at the Kuckucksnest in Aachen! We have more than 100 registered participants and we are looking forward an exciting meeting. If you attend the first two days 9-10 October, don’t forget to book a hotel in Aachen on your own, it’s time now.
You don’t have a hotel yet? Check out this pdf: Hotels and Travel.

What’s up? The Friday links (58)
2013-09-20 | in The Friday LinksIt’s time to revive the Friday Links tradition, I just realized that it fell asleep in March…
A paper published in Science few hours ago deals with the energy release of one of the strangest mega-quakes that we have ever observed, the M8.3 Okhotsk event of 24 May 2013. The interesting thing is that is occurred in more than 600 km depth! In the same issue of the journal another paper describes attempts to perform analogue experiments of such events in the lab. If you just want to get a rough idea about the studies or have no access to science, I recommend to check out Andrew Alden’s article at kqed science. 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
