Advancing earthquake science worldwide
8 March 2023–When it comes to making a rapid estimate of ground motion and moment magnitude for an earthquake, using data from Global Navigation Satellite Systems (GNSS) might be a good alternative or addition to data from seismic stations. Researchers were able to compare how well each type of data … Continue Reading »
17 November 2022–Data collected by a large-N seismic array and distributed acoustic sensing (DAS) in Iceland offer one of the most detailed acoustic fingerprints of a meteoroid entering and disintegrating in the atmosphere. The dense record, described in Seismological Research Letters, allowed the researchers to distinguish acoustic phases that are … Continue Reading »
30 August 2022–The recurrence interval for earthquakes along some California faults may be on average 16% longer than previously estimated, according to a new study in the journal Seismological Research Letters. The revised estimates take into account a variable called event likelihood, which quantifies how likely it is that a … Continue Reading »
27 June 2022–Using a method that works backward from a set of observed earthquakes to test seismic models that fit those observations, researchers working in the Delaware Basin were able to determine whether earthquakes in the region since 2017 were caused by oil and gas operations. The new study published … Continue Reading »
16 March 2022–Seismic and acoustic data recorded 50 meters away from a research nuclear reactor could predict whether the reactor was in an on or off state with 98% accuracy, according to a new study published in Seismological Research Letters. By applying several machine learning models to the data, researchers … Continue Reading »
14 March 2022–Christopher DuRoss of the U.S. Geological Survey, Golden, Adam Ringler of the U.S. Geological Survey, Albuquerque, and Vaclav Vavrycuk of the Institute of Geophysics in the Czech Republic, are the recipients of SSA’s 2021 Outstanding Reviewer awards. In recent interviews, the recipients agreed that reviewing is an essential … Continue Reading »
