How Did Mexico’s Early Warning System Perform During Recent Earthquakes?

7 February 2018–Mexico’s earthquake early warning system gave Mexico City’s residents almost two minutes of warning prior to the arrival of strong seismic waves from the September 7, 2017 Tehuantepec earthquake centered off the southern coast of Mexico, according to a report in the journal Seismological Research Letters. The magnitude 8.2 … Continue Reading »

Early Warning System Tested against Chilean Great Quakes

7 February 2018–Researchers testing a satellite-based earthquake early warning system developed for the U.S. West Coast found that the system performed well in a “replay” of three large earthquakes that occurred in Chile between 2010 and 2015. Their results, reported in the journal Seismological Research Letters, suggest that such a system … Continue Reading »

ShakeAlert System Continues Progress toward Public Use

6 December 2017–A decade after beginning work on an earthquake early warning system, scientists and engineers are fine-tuning a U.S. West Coast prototype that could be in limited public use in 2018. In two papers published December 6 in Seismological Research Letters, researchers describe the key components and testing platform … Continue Reading »

Parkfield Segment May Host Occasional Large Earthquakes

29 November 2017— Although magnitude 6 earthquakes occur about every 25 years along the Parkfield Segment of the San Andreas Fault, geophysical data suggest that the seismic slip induced by those magnitude 6 earthquakes alone does not match the long-term slip rates on this part of the San Andreas fault, … Continue Reading »

Call for Papers: SRL Focus Section on the Collaboratory for the Study of Earthquake Predictability: New Results and Future Directions

14 November 2017 – Seismological Research Letters (SRL) announces a “Focus Section on the Collaboratory for the Study of Earthquake Predictability: New Results and Future Directions.” The global Collaboratory for the Study of Earthquake Predictability (CSEP) was formed in 2007 at the Southern California Earthquake Center (SCEC) with support from the W. … Continue Reading »
