Advancing earthquake science worldwide
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 »
11 June 2019–New mechanical modeling of a network of active strike-slip faults in California’s Imperial Valley suggests the faults are continuously linked, from the southern San Andreas Fault through the Imperial Fault to the Cerro Prieto fault further to the south of the valley. Although more studies are needed to … Continue Reading »
26 March 2019–A new high-resolution map of a poorly known section of the northern San Andreas Fault reveals signs of the 1906 San Francisco earthquake, and may hold some clues as to how the fault could rupture in the future, according to a new study published in the Bulletin of … Continue Reading »
15 February 2019–Hourly water level records collected from tide gauges can be used to measure land uplift caused by episodic tremor and slip of slow earthquakes in the Cascadia Subduction Zone, according to a new report in the Bulletin of the Seismological Society of America. Global Positioning System (GPS) data … Continue Reading »
18 December 2018–A closer look at small earthquakes that took place at the Oroville Dam in California’s Sierra Nevada foothills in February 2017—near the time when the dam’s spillway failed—suggest that the seismic activity was related to reservoir discharge that opened and closed fractures in the rock below the spillway. … Continue Reading »
