As the Syrian Civil War enters its sixth year, seismic hazard might not immediately come to mind, but there is a reason it should. According to research presented at the AGU Fall Meeting, new estimates of the number of earthquake fatalities that could be expected in Turkey under several potential earthquake scenarios are 3 to 20 percent higher when Syrian refugees are counted in seismic risk models. In the April issue of EARTH Magazine, read how researchers at the University of Arkansas in Fayetteville made this discovery, which will provide vital data for disaster mitigation and response efforts.
San Diego county can rest a bit more easily should a major earthquake, or another disaster disrupt supply of water it imports. The 25 year project investing in San Diego's water infrastructure won the American Society of Civil Engineers' Outstanding Civil Engineering Achievement (OCEA) Award.
This paper describes the tectonic summaries for all magnitude 7 and larger earthquakes in the period 2000–2015, as produced by the U.S. Geological Survey National Earthquake Information Center during their routine response operations to global earthquakes. The goal of such summaries is to provide important event-specific information to the public rapidly and concisely, such that recent earthquakes can be understood within a global and regional seismotectonic framework. We compile these summaries here to provide a long-term archive for this information, and so that the variability in tectonic setting and earthquake history from region to region, and sometimes within a given region, can be more clearly understood.
The surge in recent years of earthquake activity associated with some oil and gas operations, most notably in Oklahoma, has spurred a range of actions and responses from state geoscientists and regulators. States have taken measures to monitor these earthquakes and moderate the activities that may be causing them, particularly the deep underground injection of large volumes of wastewater. Many states with extensive oil and gas operations but little or no increased earthquake activity have also adopted practices to prevent and prepare for potential induced earthquakes in their area.
