Location Of Microearthquakes Induced By Hydraulic Fracturing [PDF]
, 1993 This paper examines the problem of locating microearthquakes induced by hydraulic fracturing using seismic arrival time data. In addition to the use of absolute arrival times measured for individual events, we consider the use of differential arrival ...
