Advancing earthquake science worldwide
By mathematically modeling the movements of a locomotive that toppled from the tracks north of San Francisco during the city’s infamous 1906 earthquake, researchers have calculated a lower limit on the earthquake ground motion at the spot of the tipped train. Their report in the journal Seismological Research Letters concludes … Continue Reading »
28 December 2018–A low-cost earthquake early warning system provided a map of expected ground shaking around the epicenter of February’s magnitude 6.4 Hualien earthquake within two minutes of the mainshock’s start, according to a new study by seismologists at the National Taiwan University, which deployed the system. The predicted shake … Continue Reading »
SAN FRANCISCO (3 December 2018) – The Seismological Society of America (SSA) announced today the appointment of Allison Bent, a research seismologist with Natural Resources Canada, as editor-in-chief of Seismological Research Letters (SRL). Accessible by all SSA members and available in more than 1,300 academic, government and corporate institutions worldwide, … 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 »
26 September 2018–The epicenter of the 3 September 2017 nuclear test explosion in North Korea occurred about 3.6 kilometers northwest of the country’s first nuclear test in October 2006, according to a new high-precision analysis of the explosion and its aftermath. The study published in Seismological Research Letters by Lian-Feng Zhao … 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 »
