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

    2017-07-07 | Christoph Grützner in Meeting

    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

    2017-07-04 | Christoph Grützner in 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

    2017-07-03 | Christoph Grützner in Meeting

    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)

    2017-07-01 | Christoph Grützner in Paper

    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

    2017-06-27 | Christoph Grützner in Paper

    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

  • Minoan Earthquakes: Breaking the Myth through Interdisciplinarity

    2017-06-19 | Various Authors in Paper

    In a recent post on this forum, Angela Landgraf shared a digest of the long and winding road having led to the publication of Seismicity, Fault Rupture and Earthquake Hazards in Slowly Deforming Regions. Reading this post in the midst of wrapping up the edition of our Minoan Earthquakes volume, I could only sympathize with her concerns and hopes for the future of edited books at a time when impact factors and other author-level metrics all too often dictate academic choices.

    Four years and a half (!) after the Out of Rubble Leuven workshop (29-30 November 2012), we are proud to announce the publication of Minoan Earthquakes: Breaking the Myth through Interdisciplinarity at Leuven University Press. Reasons for such delay are manifold but chief among them is our editorial choice of producing a coherent volume that might be used as an up-to-date toolbox for readers interested in the broader field of archaeoseismology – not just Minoan archaeoseismology – and its (necessary) relationship to other, better established, disciplines. This choice is reflected by the structure of the book and breadth of topics covered by its authors, ranging from seismology, paleoseismology, geophysics, architecture, engineering and, of course, Minoan archaeology. Although we will ultimately leave readers to judge how successful we were in this endeavor, we are encouraged by Iain Stewart’s appreciation of the volume: more

    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

  • Use late-Holocene tidal notches as earthquake geological effects?

    2017-05-30 | Various Authors in Paper

    Tidal notches are a generally excepted sea-level marker. Particularly in the Mediterranean, those shoreline indicators are oftentimes used to infer coastal coseismic activity when they occur displaced from present day sea-level. Now, paleoseismologists should be able to visualize coastal evolution in order to better understand coseismic history. more
