A physics-based method estimates the duration of earthquakes’ coseismic phase and can help improve the precision of coseismic slip models and magnitude estimates.
There’s a seismometer on Mars, and it’s been busy! Download our free illustrated poster.
Researchers look to the fossil rock record to unearth the driving forces for variable seismic speed through subduction zones.
Passive seismic data from a station atop Germany’s highest peak reveal a 15-year record of permafrost degradation, suggesting that this technique could be used for long-term environmental monitoring.
InSight data hint that shifting carbon dioxide ice loads, illumination changes, or solar tides could drive an uptick in marsquakes during northern summer—a “marsquake season.”
A combination of waveform tomography and hydrothermal modelling allows characterizing the mechanisms and reach of fluid flux and ocean plate cooling near mid-ocean ridges with unprecedented detail.
What causes slow earthquakes in subduction zones? New insights from numerical models suggest that a mixture of strong and weak rocks might be the cause.
A decade of study into the Virginia earthquake that damaged D.C. and reverberated up and down the Atlantic coast in 2011 has shed light on rare, but risk-laden, seismicity in eastern North America.
A 4D back-projection method revealed that aftershocks of the 2015 earthquake beneath the Ogasawara (Bonin) Islands occurred as deep as about 750 kilometers.
Seismic waveform inversion is inherently non-linear. New objective functions based on optimal transport theory mitigate nonlinearity yielding stable solutions without need for accurate initial models.
