At the XIX INQUA congress in Japan I had the chance to see the surface ruptures of the 1891 Nobi earthquake during the mid-congress excursion M-2. This quake caused huge damage, but more interestingly for me, it produced amazing surface ruptures which are preserved even more than a hundred years after the event. The M7.5-M8 quake occurred in a mountainous area and was mainly strike-slip (more than 8 m!), but significant vertical uplift was found at step-overs. In 1991, the wonderful Neodani Fault Museum opened to the public, its main attraction being a paleoseismological trench exhibiting more than 5 m of vertical offset! Simply astonishing. Thanks to Atsumasa Okada, Heitaro Kaneda and Keitaro for this great excursion! more

Final deadline for international workshop “Advances in Active Tectonics and Speleotectonics” in Vienna tomorrow!2015-07-30 | in Meeting
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 http://www.nhm-wien.ac.at/AATS_Workshop_2015
Looking forward to seeing you in Vienna!

2015 GSA Session “Estimating the Timing and Characteristics of Continental Earthquakes from Geologic Data”2015-07-22 | in Meeting
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“. more

The INQUA 2015 congress in Nagoya will not only be the place to catch up with latest science news, but also to elect new commissions and project leaders and to plan and co-ordinate the ongoing activities for the inter-congress period. Therefore, think about joining the relevant business meeting! INQUA is organized in several commissions, of which TERPRO (Terrestrial Processes) is the one which covers paleoseismology, active tectonics and tectonic geomorphology. The IFG Palacte (Int’l Focus Group Paleosesimology/active tectonics) is a sub-organization of TERPRO itself. The TERPRO Business Meeting will be held on the evening (19:00-20:30) of Tue, 28 July in room 431, and will focus on the new Commission structure and programs for the intercongress period 2015 – 2019. more

Some weeks ago we advertised the NSF-sponsored workshop on Future Directions in Tectonics. Yesterday, Kevin Mahan announced that the workshop will be postponed. Read the message he circulated: more
Symposium on Mega Earthquake Induced Geo-disasters – The field trips part II: Qipan gully debris flow
It’s Friday – but instead of the Friday links I have the story of a giant post earthquake debris flow in the Wenchuan area for you. As I already announced in my last post about the field trip to the Wenchuan earthquake epicenter in frame of the International Symposium on Mega-Earthquake Induced Geo-disasters and Long Term Effects in Chengdu, China, I still wanted to blog about the Qipan gully debris flow that we also visited during the field trip. After giving you some background information I will take you on the hike with us. We will first see massive destruction in the residential area and then have a look at the debris flow deposits and some mitigation structures while climbing up the gully. Come on, let’s go! more
In my last post I blogged about the International Symposium on Mega Earthquake Induced Geo-disasters and Long Term Effects in Chengdu, China, and now I want to report about one of the field trips that I participated after the symposium. While we spent the morning and early afternoon at the Qipan gully to look at a giant debris flow that occurred five years after the earthquake, in the afternoon we had the chance to visit the memorial site of the 2008 Mw 7.9 Wenchuan earthquake, which is basically the collapsed building of a middle school close to the epicenter that was left as it was after the earthquake. I want to report about this site first because it is more about the earthquake itself. In my next post I will report about the Qipan gully debris flow. more
The 4th International Symposium on Mega Earthquake Induced Geo-disasters and Long Term Effects in Chengdu, China2015-05-21 | in Meeting
From May 8 – 13, 2015 the 4th International Symposium on Mega Earthquake Induced Geo-disasters and Long Term Effects was held in Chengdu, China, at the 7th anniversary of the Mw 7.9 Wenchuan earthquake that occurred on May 12, 2008. Since Chengdu was basically on my way back from the Fucino 2015 PATA Days in Italy to my working place in Beijing, I was in the lucky situation to be able to participate the symposium and drive away the post-PATA-blues with exciting talks, discussions and field trips that obtained a new dimension of relevance in face of the April 25 Nepal earthquake. I thought this meeting might be interesting for the paleoseismicity community and as Christoph told me, the current example of the Nepal quake that apparently didn’t produce any surface rupture shows again the importance of earthquake environmental effects (EEEs) for paleoseismologists. So I decided to put together a little report about the symposium and in a coming post I also want to share a report and some pictures from the post-symposium field trips. more
Our colleagues in Belgium have reasons to celebrate! At the Membach station they’re monitoring seismic activity for 40 years now, and 20 years ago the superconducting gravimeter started working. To commemorate this the Royal Observatory of Belgium and the Public Services of Wallonia organize a scientific workshop on Earthquake activity and hazard in northwest Europe. The workshop will be held on 15 October 2015 at the Gileppe Dam Tower.

The workshop “Tectonic and geodynamic evolution of Eastern Iran” will be held in both Tehran (2 Nov) and Birjand (3-6 Nov). It will comprise 3 days of field excursion around Birjand showcasing the variety of Sistan’s geological highlights (from ophiolites, deformation events, sedimentary basins to ore-mineralizations), that will be open to ~60 people. more
