Advancing earthquake science worldwide
SSA awarded Shanna Chu, Danielle Lindsay and Christina Tsarsitalidou with travel grants to present their research at technical conferences later this Fall. The grants are part of the Global Travel Grant program, which was established to support the careers of student and early-career members. Two student recipients are heading to … Continue Reading »
16 August 2021–Earthquakes are happening all the time inside Louisa Brotherson’s lab. Tiny ones, at least—and the strike-slip faults involved occur in Perspex plastic, not rock. Using a machine called a triaxial deformation apparatus, Brotherson can apply different pressures and stresses on the plastic to mimic the conditions that lead … Continue Reading »
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 »
15 July 2021–For Amir Salaree, the road to studying tsunamis began when he was a physics major at the University of Tehran, “looking for simple, real-world applications of all the beautiful math and physics that I was learning which would be useful to people,” he recalled. Visiting a friend in … 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 »
