Microearthquakes with magnitudes ranging between-6 and-2 have been observed in three
successive massive injections of water at the Hot Dry Rock Geothermal Energy …

Seismic imaging using microearthquakes induced by hydraulic fracturing produces a three-
dimensional (3-D), S-wave velocity model of the fractured zone, improves the calculated …

Microearthquakes with magnitudes between− 6 and− 2 have been observed in three
successive massive injections of water at the hot dry rock geothermal energy development …

We calculated high-resolution relative locations and full moment tensors for
microearthquakes that occurred before, during, and following EGS stimulation experiments …

Microearthquakes induced by hydraulic fracturing in crystalline rock at a depth of 3.5 km
were located with a precision of better than 30 m to obtain information about the geometry …

Seismicity accompanying hydraulic injections into granitic rock is often diffuse rather than
falling along a single plane. This diffuse zone of seismicity cannot be attributed to systematic …

An injection experiment at the Coso geothermal field in eastern California in March 2005
caused a swarm of microearthquakes that was recorded by a local network of three …

One of the most promising techniques for monitoring the effects of hydraulic stimulation or
fracturing is the use of the induced microseismicity to define the shape and orientation of the …

We investigate the temporal and spatial dependence of source parameters of micro-
earthquakes (< M3) before and during water injection at the Northwest Geysers between …

ABSTRACT In Hot Dry Rock (HDR) or Hot Fractured Rock (HFR) geothermal energy
development, micro-earthquake events were observed to evaluate the location and size of …
