Tsunami modeling with dynamic seafloors: a high-order solver validated with shallow water benchmarks
Thomas Melkior, Harsha S Bhat, Faisal Amlani
Recent scientific studies have suggested that, in certain physical configurations, the time-dependent behavior of earthquake rupture and seafloor (bathymetry) motion can leave obse…
FASTDASH: An Implementation of 3D Earthquake Cycle Simulation on Complex Fault Systems Using the Boundary Element Method Accelerated by H-matrices
Jinhui Cheng, Harsha S. Bhat, Michelle Almakari +2
Fault systems have geometrically complex structures in nature, such as stepovers, bends, branches, and roughness. Many geological and geophysical studies have shown that the geomet…
Direct Estimation of Earthquake Source Properties from a Single CCTV Camera
Soumaya Latour, Mathias Lebihain, Harsha S. Bhat +4
We present a direct measurement of the slip-rate function from a natural coseismic rupture, recorded on March 28, 2025, during the 7.7 Mandalay earthquake (Myanmar). This mea…
A rate-and-state friction based criterion for the probability of earthquake fault jumps
Sylvain Michel, Oona Scotti, Sebastien Hok +5
Geometrical complexities in natural fault zones, such as steps and gaps, pose a challenge in seismic hazard studies as they can act as obstacles to seismic ruptures. In this study,…
Volumetric (dilatant) plasticity in geodynamic models and implications on thermal dissipation and strain localization
Ekeabino Momoh, Harsha S. Bhat, Stephen Tait +1
Here, we present a new thermomechanical geodynamic, numerical implementation that incorporates Maxwell viscoelastic rheology accounting for temperature-dependent power-law dislocat…
