Variable seismic responsiveness to stress perturbations along the shallow section of subduction zones: The role of different slip modes and implications for the stability of fault segments

Assessing the stability state of fault interfaces is a task primary interest not only for seismic hazards, but also understanding how earthquake machine works. Nowadays it well known that relationship exists between slow and fast earthquakes; moreover, more evident such connection quite diffuse all over Earth. In this paper, we perform spatial temporal analysis both geodetic seismic—non-volcanic tremors, low-frequency events (LFEs), regular earthquakes—time series. We focus on clustering properties different kinds seismicity their response to stress perturbations. Earth tides large earthquakes are used as source additional stress.

Our suggests tremors become sensitive Earth-tide perturbations interface seismically locked. Therefore, show similar tidal This feature accompanied by relatively lower coefficients variation.
