Low-frequency earthquakes in the Mexican sweet spot
We use data from the Meso?America Subduction Experiment to detect and locate low?frequency earthquakes (LFEs) in the Mexican subduction zone. We use visually?identified templates to perform a network waveform correlation search that produced ~17,000 robustly detected LFEs that form 15 distinct famil...
