Earthquake extraction and correlation energy at Long Beach, California seismic survey

Earthquake Recordings

With the San Andreas Fault running through California, the Long Beach survey picks up many events, both big and small. We present waveforms from a nearby (approximately $15$  km east of the survey) M$2.4$ event in Yorba Linda, California, and a further away (approximately $250$  km southeast of the survey) M$4.9$ event in Mexicali, Mexico. Given the spatial dimensions and duration of the Long Beach array, both events could potentially be used for resolving structures and velocities at the reservoir scale.
