Real-time probabilistic tsunami forecasting in Cascadia from sparse offshore pressure observations
Stefan Henneking, Fabian Kutschera, Sreeram Venkat +2
Near-field tsunami early warning in the Cascadia Subduction Zone is limited by sparse offshore observations. We investigate whether a hypothetical network of 175 ocean-bottom press…
Localization of fast and slow slip in fault gouge and fracture energy scaling
Dmitry I. Garagash, Alice-Agnes Gabriel
The localization of slow and fast slip in fault gouges may play a crucial role in understanding the mechanics of earthquakes and slow slip events. Here, we investigate the fracture…
Dynamic restrengthening and fault heterogeneity explain megathrust earthquake complexity
Jeremy Wing Ching Wong, Alice-Agnes Gabriel, Wenyuan Fan
Megathrusts host Earth's largest earthquakes. Understanding the physical conditions controlling their rupture dynamics is critical for assessing seismic and tsunami hazards. These…
Real-time Bayesian inference at extreme scale: A digital twin for tsunami early warning applied to the Cascadia subduction zone
Stefan Henneking, Sreeram Venkat, Veselin Dobrev +5
We present a Bayesian inversion-based digital twin that employs acoustic pressure data from seafloor sensors, along with 3D coupled acoustic-gravity wave equations, to infer earthq…
Training the Next Generation of Seismologists: Delivering Research-Grade Software Education for Cloud and HPC Computing through Diverse Training Modalities
M. Denolle, C. Tape, E. BozdaÄ +28
With the rise of data volume and computing power, seismological research requires more advanced skills in data processing, numerical methods, and parallel computing. We present the…
