A new seafloor seismic network detected low-frequency tremor on the subduction zone interface offshore northern Japan, indicating regions of slow slip in close proximity to shallow megathrust events.Read More »Natural Hazards
Video footage gathered from social media is used to reconstruct the timing and likely source(s) of the tsunami generated by the 2018 Palu earthquake.Read More »Geochemistry, Mineralogy, Volcanology
Seismometers near Iceland’s Bárðarbunga volcanic system pinpointed thousands of earthquakes in 2014–2015, revealing where molten rock was moving underground before any eruptions occurred.Read More »Geology & Geophysics
New observations of recently discovered gravity perturbations that precede seismic waves have the potential to improve earthquake early-warning systems in California and other tectonic settings.Read More »Geology & Geophysics
By reanalyzing seismic records, researchers found a plethora of tiny earthquakes in Southern California that trace new fault structures and reveal how earthquakes are triggered.Read More »Geology & Geophysics
Using the prevalence of unstable rock formations in Israel’s Negev Desert, researchers determined that historical earthquakes in the region were weaker than previously thought.Read More »
Using nearly 50 years of satellite data and records stretching back millennia, scientists determine the relative frequency—and the erosional power—of monsoon- and earthquake-induced landslides in Nepal.Read More »Geology & Geophysics
New methods of machine learning are bringing the phase arrival time and polarity picking used for automatic determination of earthquake fault planes to accuracies better than human analysists.Read More »
