3D Dynamic Rupture Modeling of the 6 February 2023, Kahramanmaraş, Turkey Mw 7.8 and 7.7 Earthquake Doublet Using Early Observations

The Seismic Record, 2023
The 2023 Turkey earthquake sequence involved unexpected ruptures across numerous fault segments. We present 3D dynamic rupture simulations to illuminate the complex dynamics of the earthquake doublet.

Rupture-dependent breakdown energy in fault models with thermo-hydro-mechanical processes [PDF]

Solid Earth, 2020
Substantial insight into earthquake source processes has resulted from considering frictional ruptures analogous to cohesive-zone shear cracks from fracture mechanics.

RUPTURE IMAGING FOR THE 30 OCTOBER TSUNAMIGENIC EARTHQUAKE IN THE EASTERN AEGEAN SEA [PDF]

Science of Tsunami Hazards, 2021
On 30 October 2020, an earthquake with a moment magnitude Mw=7.0 occurred in the Aegean Sea close to the coasts of Turkey and of the Greek Island of Samos. The earthquake generated a local tsunami in the area, which had maximum amplitude of 2 meters, and

Nucleation Mechanism and Rupture Dynamics of Laboratory Earthquakes at Different Loading Rates

Applied Sciences, 2023
The loading rate of tectonic stress is not constant during long-term geotectonic activity and significantly affects the earthquake nucleation and fault rupture process. However, the mechanism underlying the loading rate effect is still unclear.
