Focal Mechanism Determination Using High Frequency Waveform Matching and Its Application to Small Magnitude Induced Earthquakes
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2010)
We present a new method using high frequency full waveform information to determine the
focal mechanisms of small, local earthquakes monitored by a sparse surface network. During the
waveform inversion, we maximize both ...
Downhole microseismic monitoring of hydraulic fracturing: a full-waveform approach for complete moment tensor inversion and stress estimation
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2010)
Downhole microseismics has gained in popularity in recent years as a way to characterize hydraulic fracturing sources and to estimate in-situ stress state. Conventional approaches only utilize part of the information ...
