Final deadline for international workshop “Advances in Active Tectonics and Speleotectonics” in Vienna tomorrow!

Just as a reminder for all interested in visiting Vienna in September 21–24, 2015 and participate on the international workshop “Advances in Active Tectonics and Speleotectonics”:

The final deadline for registration and abstract submission is approaching tomorrow (July, 31st, 2015).

There will be great field trips to active faults in the Vienna Basin (currently excavated) and to Austrian caves showing ongoing deformation. For more details, dates and contacts please visit the website

Looking forward to seeing you in Vienna!

Guest blog by Yu Zhou (Oxford): The 2013 Mw 7.7 Balochistan earthquake in Pakistan: NOT SO UNUSUAL

In 2013, a MW7.7 earthquake struck Balochistan, caused a huge surface offset and triggered a small tsunami in the Arabian Sea. Immediately, the apparently strange fault behaviour caused the attention of scientists world wide and a number of papers were published. The discussion is highly interesting and still ongoing. This an interesting case for paleoseismologists, too, not only because of the cascading earthquake effects, but also because of the surface rupture distribution, from which we might learn some important lessons for our future work. Now my colleague Yu Zhou and his colleagues from Oxford University published a new paper on this event, arguing that it might be not as unusual as it seems. Their research is based on the analysis of Pleiades stereo satellite imagery, which has proven to be a very useful data source already. Yu send me a nice summary of his recent research: Continue reading “Guest blog by Yu Zhou (Oxford): The 2013 Mw 7.7 Balochistan earthquake in Pakistan: NOT SO UNUSUAL”

2015 GSA Session “Estimating the Timing and Characteristics of Continental Earthquakes from Geologic Data”

The 2015 GSA Annual Meeting will be held in early November in Baltimore and since the deadline is approaching (11 August) it is time to check paleoseismology sessions. One of the many interesting sessions will be chaired by our colleagues Mark Quigley and Tim Stahl: “T186 – Estimating the Timing and Characteristics of Continental Earthquakes from Geologic Data”. Tim told me that there will be “some great invited speakers lined up speaking on paleoliquefaction, lake varve deposits and San Andreas fault paleoseismology“.

Literature update

Lots of paleoseismology and tsunami studies are currently being published… Here’s my update on the latest papers, including: Surface ruptures, seismic swarms, tsunamites, Asian tectonics, slip rates and archaeoseismology. Plus: A very interesting study on the 1911 Chon-Kemin M8.0 earthquake in the Kazakhstan/Kyrgyzstan border region, the source process reconstruced from analogue seismograms. Thanks to Ramon Arrowsmith for pointing me to this one. Enjoy!

Paleoseismological field work in Kyrgyzstan

A few weeks ago I spent ten days of field work in the Suusamyr Valley in Kyrgyzstan. In the framework of the EwF Project and COMET a team from Oxford (Eleanor Ainscoe, Austin Elliott, Richard Walker) and Kyrgyzstan (Kanatbek Abdrakhmatov, Azat Moldobaev) re-visited the epicentral area of the 1992 MS7.3 Suusamyr earthquake. This thrust earthquake is quite special for it produced intense and widespread secondary earthquake environmental effects (landslides, rockfalls, secondary ruptures, mud eruptions, etc.), but remarkably short primary surface ruptures only. Actually, surface ruptures of several metres height were found near the Suusamyr river, but limited to few hundreds of metres in length. Some 25 km to the west, another set of surface ruptures appeared, which were only about 1 m in height and less than 3 km long. Here are some impressions from our field work.

Italy’s Database of Individual Seismogenic Sources (DISS) v. 3.2.0 now online

Great news from Italy – A new version of the Database of Individual Seismogenic Sources (DISS) is now online! A huge amount of work went into this latest release which has several important updates and a fantastic new amount of data. Our colleague Umberto Fracassi sent me the following description of the new features:
