Low-Frequency Quakes Have Modest Effect on Slow Earthquake Cycle

by Marcos Moreno 5 September 202331 August 2023

Slow slip phenomena on subdaily scales, captured by seismic and GNSS data, show that low-frequency earthquakes are incidental to larger magnitude slow earthquakes, in which aseismic slip dominates.
