摘要: We found that repeated slow slip events observed on the deeper interface of northern Cascadia subduction zone, which were at first thought to be silent, have unique nonearthquake seismic signatures. Tremorlike signals correlate temporally and spatially with identified from crustal motion data spanning past 6 years. During period between slips, tremor activity is minor or nonexistent. call this associated phenomenon episodic (ETS) propose ETS can used as a real-time indicator stress loading megathrust earthquake zone.
