Near Real-Time Repeating Earthquake Monitoring System

Description: 

Repeating earthquakes are the result of asperities creeping along the plate interphase. Under stable conditions, repeating earthquakes show relatively constant recurrence times and quasi-identical waveforms. Nonetheless, recurrence time and waveform similarity of these events may vary over time likely due to temporal variations of the plate interface coupling, i.e., due to velocity changes of the interface creeping. Daily monitoring of RE may thus help to assess the interface current state in those terms. Here, we present a near real-time repeating earthquake monitoring system designed to continuously detect repeating earthquakes along the Mexican subduction zone to have updated insights of seismotectonic processes when initiating. Previous studies have shown that repeating earthquakes may act as an indicator for the nucleation of large earthquakes and may provide evidence for changes in the slip rates associated with stress transfer due to the interaction between slow slip events and moderate to large earthquakes (M>7.0).
