Advancing earthquake science worldwide
23 May 2019–SSA is pleased to announce the recipients of several of the Society’s awards for 2019. The Harry Fielding Reid Medal, the Charles F. Richter Early Career Award and the Frank Press Public Service Award are among the highest honors conferred by the Society. The Reid Medal recipient is Karen Fischer of … Continue Reading »
26 April 2019–A day after the 30 November 2018 magnitude 7 earthquake in Anchorage, Alaska, U.S. Geological Survey scientists Robert Witter and Adrian Bender had taken to the skies. The researchers were surveying the region from a helicopter, looking for signs of ground failure from landslides to liquefaction. As Witter … Continue Reading »
26 April 2019–Using a dense sensor network that scanned the United States between 2003 and 2014, researchers have identified areas within the country marked by a persistent seismic signal caused by industrial processes. At the 2019 SSA Annual Meeting, Omar Marcillo of Los Alamos National Laboratory said that he and … Continue Reading »
26 April 2019–About 16.7 million years ago, the Columbia River flood basalt event covered much of eastern Oregon, parts of western Idaho and southern Washington state. The massive outpouring of basalt lava, covering about 63,000 square miles of the Pacific Northwest, is thought to have originated from the Yellowstone volcanic … Continue Reading »
26 April 2019–In the past decade scientists have been experimenting with metamaterials, artificial materials designed with periodic internal structures to give them properties not found in natural materials. Depending on their internal geometry and composition, researchers have found that they can control waves propagating through some of these materials, filtering … Continue Reading »
25 April 2019–Small earthquakes in Ohio, Pennsylvania, West Virginia, Oklahoma and Texas can be linked to hydraulic fracturing wells in those regions, according to researchers speaking at the SSA 2019 Annual Meeting. While relatively rare compared to earthquakes caused by wastewater disposal in oil and gas fields in the central … Continue Reading »
