The Music of Fault Zones
By Amir Allam, Hongrui Qiu, Fan-Chi Lin, and Yehuda Ben-Zion, Department of Geology & Geophysics
We deployed 108 seismometers in a dense line across the most active fault in Southern California (the San Jacinto fault) and recorded 50 small earthquakes. This animation shows how the fault zone itself is resonating due to the passing waves. The earthquakes are exciting normal mode oscillations - just like on a guitar string - directly underneath the seismometers. This is due to a zone of highly damaged rocks near the active fault which act to trap passing seismic energy. This resonance decreases in amplitude with increasing distance from the fault zone.
