15 May 2018–Nyiragongo in the Democratic Republic of the Congo is among the world’s most active volcanoes, with a persistent lava lake as one of its defining features. In a talk at the 2018 SSA Annual Meeting, Adrien Oth of the European Center for Geodynamics and Seismology discussed how he … Continue Reading »
[Leer en español] 15 May 2018–New seismic hazard and risk models developed for South America suggest that more than 160 million people—about one-third of the continent’s total population—live in areas with significantly elevated seismic hazard, according to a report discussed at the 2018 SSA Annual Meeting. Risk is greatest in … Continue Reading »
Nuevos modelos de peligrosidad y riesgo sísmico desarrollados para América del Sur sugieren que más de 160 millones de personas – alrededor de un tercio de la población total del continente – viven en áreas con un riesgo sísmico significativamente más elevado, según un reporte presentado durante la Reunión Anual … Continue Reading »
15 May 2018–Record cold temperatures during the winter of 2014 in the Midwestern United States froze large parts of the Great Lakes—and inadvertently offered seismologists a chance to learn more about the seismic signals created by the lakes’ wind-driven waves. The deep freeze stilled the waves and created a period … Continue Reading »
15 May 2018–Scientists monitoring the vibrations of natural rock arches have found that the resonant frequencies of arches undergo dynamic changes from day to day, according to research presented at the 2018 SSA Annual Meeting. University of Utah doctoral student Paul Geimer and colleagues are analyzing these frequency changes to … Continue Reading »
15 May 2018–Almost 70 years later, the man remembers the August day in Playa Rincon, when he clung to the top of an almond tree to survive a tsunami where the waters rushed about 700 meters inland after a magnitude 8.1 earthquake. His recollections and other astonishing eyewitness accounts of … Continue Reading »
