11 December 2018–Using data gleaned from historical reports, researchers have now identified the sources of some of the most destructive Indonesian earthquakes in Java, Bali and Nusa Tenggara, using these data to independently test how well Indonesia’s 2010 and 2017 seismic hazard assessments perform in predicting damaging ground motion. The … Continue Reading »
6 November 2018–A bleached fringe of dead marine algae, strung along the coastlines of two islands off the coast of Chile, offers a unique glimpse at how the land rose during the 2016 magnitude 7.6 Chiloé earthquake, according to a new study in the Bulletin of the Seismological Society of … Continue Reading »
31 October 2018–The depth of the rock layer that serves as the disposal site for wastewater produced during unconventional oil extraction plays a significant role in whether that disposal triggers earthquakes in the U.S., according to a new study that takes a broad look at the issue. The research published … Continue Reading »
16 October 2018–Underwater explosions detonated by the U.S. Navy to test the sturdiness of ships’ hulls have provided seismologists with a test opportunity of their own: how much can we know about an underwater explosion from the seismic and acoustic data it generates? In a study published in the Bulletin … Continue Reading »
25 September 2018–The seasonal filling and emptying of reservoirs in India can cause measurable deformation of the surrounding rock, reducing the strength of nearby faults and potentially triggering earthquakes, according to two new papers published in the Bulletin of the Seismological Society of America. Researchers in India used global positioning … Continue Reading »
22 August 2018–The bright flashes that lit up the evening skies near Detroit, Michigan earlier this year were not the only signs of the meteor that disintegrated in the atmosphere on 17 January 2018.
