  • Link tectonic processes to the seismic cycle: A 2-Myr-long seismite record from NE Tibet

    A recent study investigated disturbances that preserved in the upper 260 m of a 723-m deep core drilled on the crest of a thrust-cored anticline in the western Qaidam Basin, NE Tibet.

    1. Key Points:
    • We interpret micro-faults, soft-sediment deformation, slumps, and detachment surfaces as paleoearthquake/tectonic indicators
    • The core records five seismite clusters between 3.6 and 2.7 Ma, revealing episodic thrusting in relation to intense regional deformation
    • During the clusters, regional deformation was concentrated more in the fold-and-thrust system than along regional major strike-slip faults

  • Features of seismogenic turbidites from the Dead Sea depocenter

    A recent study investigated turbidites that preserved in a 457-m deep ICDP drilling from the Dead Sea depocenter. This is the first work to show detailed information on turbidites in the region.

    1. Key Points:

    • Seismic origin for prehistoric turbidites is established by analyzing the underlying in situ deformation structures for each turbidite
    • Data validate a previous hypothesis that soft-sediment deformation formed at the sediment-water interface in the Dead Sea
    • The new approach permits a more confident geohazard assessment by improving the completeness of a paleoseismic archive

  • Soft-sediment deformations buried beneath the center of the Dead Sea record hundreds of large earthquakes spanning the past 220,000 years

    1. Key points

    This is the first attempt to apply a computational fluid dynamic modeling-based quantitative “fossil seismograph” to develop a large earthquake record.

    The record is calibrated to historic earthquakes, for which the Dead Sea area has a famously long span, and it confirms a clustered earthquake recurrence pattern and a group-fault temporal clustering model.

    The record yields much shorter mean recurrence for large (≤ 1.4 kyr vs. 7-11 kyr) and moderate (≤ 500 yr vs. 1600 yr) earthquakes than previously obtained, thus reveals a much higher seismic hazard than previously appreciated on this slow-slipping plate boundary.

  • A WeChat platform for Paleoseismicity.org

    To increase the visibility of activities of Paleoseismicity.org to Chinese in China and around the world and to promote potential interactions with Chinese, I opened an account for Paleoseismicity.org on the WeChat platform last week. The account was named “古地震”. (“古地震” means “paleoseismicity” in English).
