Oklahoma Study Reveals Possible, Previously Unknown Sources of Earthquakes
Magnetic measurements made during low-altitude airplane flights conducted for the U.S. Geological Survey and the Oklahoma Geological Survey reveal possible deep faults that may contribute to increased seismic activity in response to wastewater injection in certain portions of Oklahoma.
New Database Covers Geometry of Majority of World’s Subduction Zones
This spring, researchers will release an expanded database that covers the geometry of most of the world’s subducting slabs, the massive pieces of the Earth’s crust that sink into the mantle at tectonic plate boundaries. Called Slab2, the updated database will help researchers determine the impact of 3-D slab shape on megathrust earthquakes. (SSA News Release)
