Between 30 September and 6 October 2020, earthquake swarm activity were detected south of Salton Sea in California, close to US-Mexico border. Swarm activity was preceded by a shallow (< 5 km depth) slow-slip event. The processes were evidenced by multiple datasets, including, dense seismometer array, GNSS, and InSAR. 

The earthquake swarm was triggered by the stress change (primary driver) of the slow-slip event. The swarm were mostly located in the basement where pore-pressure diffusion acts as a secondary driver and prolonged the swarm activity.  

Details about the study can be found in Sirorattanakul et al., 2022. 

Studying sediment fluxes from mountains to low-lying areas is important for flood risks and siltation of dams. My interest is how the erosion rates may affect InSAR surface velocities estimates due to tectonics in the Himalayas. There are potential correlation between erosion hotspots and tectonics (Hmmmm!!!!). Mandal et al. 2023 uses CRN concentrations from riverstreams to obtain erosion rates at the frontal ranges south of Himalayas in Nepal-India. Cool details!!!

The GIF shows the 3D dynamic rupture simulation during the 2023 Turkey earthquake sequence studied by Gabriel et al., 2023. It shows how the fault slip-rate propagates through the entire length of the fault (~300 km) within a matter of a couple minutes giving an idea of slip acceleration. The model reconciles geodetic, seismic observations, and regional seismotectonics (meaning ambient stress).  Such studies are extremely important towards earthquake hazard assessments.
