Advancing earthquake science worldwide
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. The meteor explosion was also captured by infrasonic microphones and seismometers, offering a rare chance to … Continue Reading »
1 August 2018–Using an array of coffee-can sized geophones deployed for about a month in backyards, golf courses and public parks, researchers collected enough data to allow them to map the depth and shape of the San Gabriel and San Bernardino sedimentary basins of Los Angeles, California. Seismologists think these … Continue Reading »
