  • AGU session on the development and application of chronometers in geomorphology

    Sarah Boulton and colleagues will convene an interesting session at the AGU Fall Meeting. They collect contributions on the development and application of geochronometres, techniques that most of us use in everyday life for dating landscape changes and fault activity. EP047: The development and application of chronometers in geomorphology.

    Session Description

    Isotopes and other quantitative tracers are widely used to quantify rates of geomorphic processes and to fingerprint sediment sources and sinks. However, these techniques, including short-lived fallout radionuclides, cosmogenic radionuclides, optically stimulated luminescence, and thermochronology, all have methodological assumptions that limit their usefulness in geomorphology. This session invites studies using geochemical methods to investigate the rates and progress of landscape change with a particular focus on geomorphic response to perturbations such as environmental change, anthropogenic impact, and tectonic drivers. We also welcome studies that consider new developments in geochronologic techniques or test the limitations and assumptions behind commonly employed methods.

  • Preliminary report on the 12 June, 2017, Lesvos (Greece) Earthquake

    On 12 June, 2017, an earthquake with a magnitude of Mw6.3 occurred south of the island of Lesvos in Greece, damaged hundreds of buildings and claimed one life. The event ruptured a NW-SE trending normal fault and had a focal depth of 13 km. Our colleagues from the National and Kapodistrian University of Athens mapped the earthquake damage and the environmental effects that accompanied the earthquake. They found mass movements, secondary cracks, and report on a small tsunami. Their report can be downloaded here (PDF, 6 mb). For a higher-resolution file (33 mb), follow this link. Many thanks to Efthymios Lekkas for sending the report. more

  • AGU2017 session on earthquake ruptures

    The following AGU session is of potential interest to the paleoseismology community:

    Earthquake Rupture Processes, Confronting Field Observations and Models (25767)

    Session Description

    In recent years, combined progresses in our understanding of earthquake mechanics and computation capabilities have allowed to develop numerical models that address earthquake mechanics at a variety of scales, from fault segmentation to co-seismic off-fault damage.

    These theoretical progresses can potentially suggest new observations that can be tested by field or geodetic studies. In parallel, innovative technics in earthquake geology and active tectonics have allowed for a significant improvement in our capacity of detailed observation of earthquake ruptures. Hence, it is time to confront high-resolution observations with numerical and theoretical models to test these models and see in which direction observation should go. We welcome contribution testing earthquake mechanic models based on observational data (geodesy, field data…) as well as contribution suggesting new potential field observation, based on theoretical or numerical developments.

  • New papers on paleoseismology, tsunami, and active tectonics (Jul 2017)

    Dear friends of active tectonics and paleoseismology,

    Although the PATA Days in New Zealand are still five months away, it will be a long flight for most of us and I suggest to think about a good read on the plane already. Below you will find the latest publications that you may find interesting. If you prefer a good old hardcover book, why not buy Minoan Earthquakes right now? Enjoy reading! more

  • Special issue on sub-aquatic paleoseismology

    A special issue on sub-aquatic paleoseismology has been published in Marine Geology. The volume 384 ‘Subaquatic paleoseismology: records of large Holocene earthquakes in marine and lacustrine sediments‘ collects papers on marine and lacustrine mass movements that can be used to decipher the earthquake history. The contributions span a wide range of different settings, from the famous Cascadia sites to Greece, and are based on presentations from the International Sedimentological Congress in Geneva (August 2014) and the AGU Fall Meeting in San Francisco (December 2014). more

  • New papers on paleoseismology, tsunami, and active tectonics (Jun 2017)

    Today’s paper list is rather long; presumably all the papers written during the winter are coming to publication now. We have lots of different topics today, so I will skip the summary and just say: Enjoy reading! more

  • PATA Days 2017: Registration is now open

    See you all in New Zealand in November!

  • Graduate Student/PostDoc Position available in Haifa – Integrated tsunami hazard study: Modeling and sediments

    This very interesting job offer was sent around by our colleague Beverly Goodman-Tchernov:

    Past tsunami events have impacted the Israeli coastline, and future tsunamis are anticipated.  Physical evidence exists both in historical written records and sedimentological field deposits. Incorporating physical evidence with computational modeling makes it possible to better understand the magnitude of past events and create realistic predictions for the future. The project is in collaboration with Geological Survey of Israel, Virginia Tech, IOLR, and the University of Haifa. It will use multi-sourced data to produce modeling scenarios for past tsunamis and produce a complex reference set of theoretical scenarios to be used in practical real-time hazard assessments. more

  • Paper: Using georadar and a mobile geoelectrics device to map shallow sediment distribution on a large scale

    [UPDATE 2017-05-14: The links now lead to the free version of the paper, available until 30 June.]

    Together with my colleagues I have published a new paper in which we describe a methodology for mapping the shallow architecture of large sedimentary basins with minimum effort and high resolution. We use two geophysical methods and combine them with point information from shallow drillings to identify different types of alluvial, fluvial, and aeolian sediments in the Orkhon Valley in Mongolia. We then show that our results fit well with a remote sensing approach. Although we did not target active faults in our study, the methodology is well suitable for detecting deformed/offset sediments without surface expression due to high erosion or sedimentation rates. That’s why I feel the study is of interest for the fault-hunting community. more
