Advancing earthquake science worldwide
10 August 2021–Earthquakes generated by controlled fluid injection at Colorado’s Rangely oil field were caused by destabilizing fault pore pressure changes, according to a new mechanistic model applied to data from the decades’ old project The Rangely experiment, conducted from 1969 to 1973, is one of the oldest studies of … Continue Reading »
[Lire en français] 8 July 2021–Seismic waves passing through the ground near Longyearbyen in the Adventdalen valley, Svalbard, Norway have been slowing down steadily over the past three years, most likely due to permafrost warming in the Arctic valley. The trend, reported in a new study published in Seismological Research … Continue Reading »
7 July 2021–Although wastewater disposal has been the primary driving force behind increased earthquake activity in southern Kansas since 2013, a new study concludes that the disposal has not significantly changed the orientation of stress in the Earth’s crust in the region. Activities like wastewater disposal can alter pore pressure, … Continue Reading »
16 June 2021–The Seismological Society of America (SSA) announced today the appointment of P. Martin Mai as editor-in-chief of the Bulletin of the Seismological Society of America (BSSA). Mai is a professor of geophysics in the Earth Science and Engineering program of the Physical Sciences and Engineering Division at KAUST. … Continue Reading »
15 June 2021–For the first time, researchers have used precariously-balanced rocks to set the formal design earthquake motions for a major existing engineered structure—the Clyde Dam, the largest concrete dam in New Zealand. Mark Stirling of the University of Otago and colleagues identified and assessed the ages of these gravity-defying … Continue Reading »
3 June 2021–A complex zone of folding and faulting that links two faults underneath downtown Salt Lake City could deform the ground during a large earthquake, according to a new study. The findings, published in the open-access journal The Seismic Record, suggest that earthquakes magnitude 5.0 and larger could cause … Continue Reading »
