Abstract

Micro-earthquake activity is reported for the first 6 months of 2011 in Long Beach, CA using a density urban exploration seismic network. Detected events include at least four times as many man-made events as possible real earthquakes indicated by repeated locations, and distinct patterns in the hour-of-day and day-of-week origin times. Some discrimination appears possible utilized the earthquake spectral behavior in the wavelet transform domain. The back-projection of the seismic data onto a prescribed fault plane of the Newport-Inglewood fault produces interesting slip patterns over a time window spanning a small earthquake.
