In case you need a good read for your summer holidays, here are the latest papers on paleoseismology and related fields. Today including a IAEA TecDoc about paleoseismology, an early paper on the Gorkha quake, coral paleoseismology, some tectonic geomorphology in Spain, clastic dykes, and tectonic uplift of an island in Chile. Enjoy!
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
New reports (on why geology matters), papers (on Nepal and Chile), a video (on Martian debris flows), some tweets and even more. Today is Friday and here are your links!
The Megablock Complex: An example from the East African Rift
Recognizing and interpreting seismite horizons (soft-sediment deformation generated by earthquakes) preserved in the sedimentary record is an underappreciated approach for paleoseismic analysis. The addition of sedimentological studies to a toolkit that includes other well-established methods, such as instrumental seismic monitoring and fault trenching, can provide a less expensive and more practical option for earthquake hazard prediction and preparation in certain areas. For example, this may be a good option in less developed regions and in areas where fault trenching may not be possible. Moreover, there is a lot that we can learn rheologically from the study of seismites that could be invaluable for modeling the behavior of the surface/near-surface during seismic activity. Similarly, investigating Quaternary strata in areas that may be prone to seismicity, which may or may not have a recorded history of major earthquakes, can illuminate important information about earthquake recurrence patterns and intervals, in much the same way as fault trenching. 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
Tomorrow, 18th June 2015, we – many voluntary student helpers and staff from RWTH Aachen University and the Geoverbund ABC-J are organizing with the Einhard-Gymnasium in Aachen, with 11-14 year old pupils the FIRST German Shake Out around midday. In special lectures and lab courses we have prepared the scholars for this event, but WHAT?? is a ShakeOut?
Here are my latest updates on papers and books that deal with paleoseismology, active tectonics, tsunamis and similar topics. There is a good portion of lake/turbidite paleoseismology with some beautiful seismites. We also have some more general tectonics/review papers, and an interesting attempt to establish a global fault database. Plus, there is an intense ongoing discussion about Kashmir and news from Napa. Enjoy!

Today is Friday and here are your links on human-caused earthquakes, induced aseismic slip, typesetting costs, flash flood video footage, and more!
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
There are articles to read, videos to watch and positions to be found: paleoseismology of Chilean turbidites, lake sediments investigated near the North Anatolian Fault, indoor footage of the Gorkha Earthquake and a discussion on Elsevier’s new sharing policies. Today is Friday and here are your links!

Paleoseismicity.org is a page dedicated to scientists and everyone else interested in paleoseismology, archeoseismology, neotectonics, earthquake archeology, earthquake engineering and related topics. Different authors irregularly write about recent papers, field work, problems, conferences or just interesting things that they come across. We intend to provide a platform for discussion and scientific exchange. Interested in joining as an author? Please contact us!
