30 September 2022–“Geodesy is quite an old research field that started pretty much when humans wanted to measure the Earth, but it is also very new, especially since the rise of space-borne radar techniques,” said Xiaohua (Eric) Xu. “Space geodesy has helped scientists to measure not just the shape, but … Continue Reading »
27 September 2022–Trapped inside the shoreline of a bay, the resonant interactions of a tsunami with regular waves can prolong the tsunami disturbance. For the 2021 magnitude 7 Acapulco, Mexico earthquake and tsunami, edge waves in the bay and the short continental shelf also had a surprisingly significant effect on … Continue Reading »

30 August 2022–The recurrence interval for earthquakes along some California faults may be on average 16% longer than previously estimated, according to a new study in the journal Seismological Research Letters. The revised estimates take into account a variable called event likelihood, which quantifies how likely it is that a … Continue Reading »
26 August 2022–Using machine learning to sift through a decade’s worth of seismic data, researchers have identified hundreds of thousands of microearthquakes along some previously unknown fault structures in Oklahoma and Kansas. The newly identified microearthquakes allowed the seismologists to map and measure earthquake clusters in the region, which has … Continue Reading »
