28 February 2017–Results of a massive new project to map and classify the earthquake shaking potential across most of the Las Vegas metropolitan area will help developers there build in safer and less expensive ways. The “Parcel Map” described 28 February in the Bulletin of the Seismological Society of America is the most extensive effort to date in the United States to map and classify soils based on their effects on earthquake shaking across an entire urban area with systematic, direct measurements at high density.
29 December 2016 – This earthquake beneath the northern part of New Zealand’s South Island, in the transition from continental strike-slip faulting in the south to subduction in the north, was one of the largest earthquakes to strike New Zealand in historic times.
The earthquake caused extensive surface deformation as it ruptured a complex series of faults with up to 13 m of predominantly horizontal displacement, resulting in unprecedented opportunities to study the surface expression of a major fault rupture. Fault displacement and strong ground motions resulted in coastal uplift, a small tsunami, and tens of thousands of landslides. The complex spatial distribution of surface ruptures and displacements, the long duration of the earthquake, and the subsequent slow slip episode in the Hikurangi subduction zone raise questions about controls on coseismic and post-seismic strain accommodation in large earthquakes, and how slip is transferred between tectonic regimes.
We solicit papers on all aspects of the earthquake. Continue for more information about the special issue.
