The Royal Belgian Institute of Natural Sciences – Geological Survey of Belgium, invites applicants for a research fellowship (postdoctoral level) in coastal paleoseismology/Quaternary environmental change. It will be a 1.5 year contract (January/February 2017- June 2018). Here’s the job advert: more
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
The 31st International Association of Sedimentologists Meeting of Sedimentology will be held in Krakow, Poland from 22 – 25 June, 2015.
The session “Application of sedimentary records in coastal environments for natural hazard assessment” aims on gathering contributions that document the application of sedimentary records of coastal changes (sea level changes) and disasters (storms, tsunamis) into coastal hazard assessment, as well as to present studies focusing on reconstructions of extreme coastal events in the past.
The 19th International Sedimentological Congress from 18 to 22 August 2014 in Geneva, Switzerland will see three sessions related to subaquatic paleoseismology and earthquake-triggered landslides and turbidites.
More sessions on tectonics will be held as well. Deadline for abstract submission and travel grant application is 30 April 2014. more
A position as Sackler-Clarendon Associate Professor in Sedimentary Geology and Sackler Fellow in Earth Sciences is available at the Department of Earth Sciences in association with St Peter’s College at Oxford University. Applications from scientists familiar with sedimentary geology, petrology, and sedimentology are welcome. Also, researchers with experience in related disciplines like stratigraphy, palaeontology, mineralogy, geochemistry, geomorphology, and tectonics are encouraged to apply. Deadline for application is 15th April 2014. more
Todays field work image is again by Elisa Kagan and shows a damaged stalagmite in the Soreq Cave near Jerusalem. Damaged stalagmites were used to reconstruct earthquake recurrence intervals. more
Today is the 200th anniversary of the first event of the New Madrid Earthquake Series. There’s still an open debate on magnitudes, intensities, causative faults, recurrence intervalls and the implication for seismic hazard. Several websites and blogs have nice posts, among them:
A new paper published in Natural Hazards today discusses post-depositional changes of tsunamites. At sites in Thailand covered by sediments of the 2004 Sumatra tsunami, Szczuciński (2011) has documented significant changes in the deposits over the last seven years. Not only were the tsunamites altered, eroded or re-deposited by animals and seasonal rain, but also vanished in certain cases.
Some good articles came up last week, and two interesting things happened in northwestern Europe. A small earthquake (M2.7-M3.4) hit northern Netherlands in the Groningen area and people claimed light house damages despite the low magnitude. The event was caused by natural gas production. The gas company, Nederlandse Aardolie Maatschappij (NAM), even has an online-formular for that! more

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!
