Advancing earthquake science worldwide
13 June 2018–Since 2007, the Collaboratory for the Study of Earthquake Predictability or CSEP has been studying earthquake forecast models to find out how well each model stacks up against its competitors, and how well each forecast predicts later seismic activity. At four centers in California, New Zealand, Europe and … Continue Reading »
2 May 2018–Researchers reexamining historical seismograms from the 1906 Meishan earthquake have uncovered a new mechanism for the quake, one of the deadliest to ever strike Taiwan. The new mechanism provides a better fit for the fault rupture expected for the magnitude 7.1. earthquake, as well as for the distribution … Continue Reading »
28 March 2018–Signs of a 1755 earthquake that was strong enough to topple steeples and chimneys in Boston can be seen in a sediment core drawn from eastern Massachusetts’ Sluice Pond, according to a new report published in Seismological Research Letters. Katrin Monecke of Wellesley College and her colleagues were … Continue Reading »
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 »
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 »
18 January 2018–There is an enduring myth that large earthquakes tend to happen during certain phases of the Moon or at certain times during the year. But a new analysis published in Seismological Research Letters confirms that this bit of earthquake lore is incorrect. After matching dates and lunar phases … Continue Reading »
