  • USGS Mendenhall Fellowship Opportunity – Cascadia Marine Geohazards

    USGS is currently recruiting a Mendenhall Postdoctoral Fellow for a project on Marine Geohazards of the Cascadia Subduction Zone, with three general areas of interest: the relationship of Quaternary sediment distribution and stratigraphy to seafloor processes and earthquake history; links between tectonic geomorphology, upper plate structure, and deeper subduction processes; and the influence of fluids and 3D structural interactions on the mechanics of subduction zone forearcs.

    A full description of the opportunity is available here:

  • IRSN report on the Napa Earthquake, California (M6, 2014-08-24)

    Our colleagues Stéphane Baize and Oona Scotti from the French IRSN finished a report on the 2014 Napa Earthquake: Post-seismic survey report, with special focus on surface faulting. On 24 August 2014, an earthquake of magnitude Mw6 occurred on the West Napa Fault in shallow depth. The quake caused significant damage, an interesting pattern of surface ruptures, and the immediate attention of hundreds of geologists. The primary and secondary effects were mapped only hours after the event, which turned out to be extremely important – a large amount of afterslip was recorded in the following days. The earthquake was not only recorded by a huge seismometer network, but the ground motion was also captured by GPS sensors and InSAR images. The new IRSN report is especially concerned with the surface faulting hazard, since this agency is responsible for the safety of nuclear installations in France.  more
