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 »
27 March 2018–Hours after the 2016 Kaikoura earthquake hit New Zealand, researchers were able to share information with first responders about where significant landsliding might have occurred to block roads and rivers, according to a new report in the Bulletin of the Seismological Society of America. The modeling approach used … 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 »
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 »
