DOI: 10.1109/tgrs.2023.3264931
Abstract: Fluids injected during hydraulic fracturing (fracking) in unconventional shale oil and gas reservoirs, geothermal system enhancement, wastewater disposal, and carbon capture and storage can induce microearthquakes. The spatiotemporal distribution of induced earthquakes is often used… read more here.

DOI: 10.1109/tmech.2018.2843558
Abstract: The low-frequency performance of active vibration isolation system depends on the low-frequency measurement ability of inertial sensor such as geophone. Bandwidth extension-based methods may serve as a cost-effective solution to increase the low-frequency measurement accuracy… read more here.
