Advancing earthquake science worldwide
28 January 2020–Earthquakes along a complex series of faults in the upper plate of New Zealand’s northern Hikurangi Subduction Margin were responsible for coastal uplift in the region, according to a new evaluation of local marine terraces. The findings, reported in the Bulletin of the Seismological Society of America, could … Continue Reading »
7 January 2020–The magnitude of the Great Lisbon Earthquake event, a historic and devastating earthquake and tsunami that struck Portugal on All Saints’ Day in 1755, may not be as high as previously estimated. In his study published in the Bulletin of the Seismological Society of America, Joao F. B. … Continue Reading »
19 November 2019–Hand-dug trenches around Leigh Lake in Grand Teton National Park in Wyoming reveal evidence for a previously unknown surface-faulting earthquake in along the Teton Fault—one occurring about 10,000 years ago. Together with evidence from the site of a second earthquake that ruptured around 5,900 years ago, the findings … Continue Reading »
29 October 2019–By combining models of magnitude 9 to 9.2 earthquakes on the Cascadia Subduction Zone with geological evidence of past coastal changes, researchers have a better idea of what kind of megathrust seismic activity was behind the 1700 Cascadia earthquake. The analysis by Erin Wirth and Arthur Frankel of … Continue Reading »
18 June 2019–The unusual appearance of deep-sea fish like the oarfish or slender ribbonfish in Japanese shallow waters does not mean that an earthquake is about to occur, according to a new statistical analysis. The study published in the Bulletin of the Seismological Society of America contradicts long-held Japanese folklore … Continue Reading »
11 June 2019–A comprehensive catalog of earthquake sequences in Texas’s Fort Worth Basin, from 2008 to 2018, provides a closer look at how wastewater disposal from oil and gas exploration has changed the seismic landscape in the basin. In their report published in the Bulletin of the Seismological Society of … Continue Reading »
