Research Development and Perspective on Slow Slip, Tremors, and Slow Earthquakes

Wang Yanzhao Shen Zhengkang State Key Laboratory of Earthquake Dynamics, Institute of Geology, CEA, Beijing 100029, China  
Seismological and geodesic observations indicate that slow slip, usually occurs in active fault zones beneath the seismogenic depth, and results in transient ground motion. Slow earthquakes, on the other hand, emit tremor-like signals within a narrow frequency band, and usually produce no catastrophic consequences. In general, slow slip and earthquakes probably correspond to deformation processes associated with releasing elastic energy in fault zones, and knowing their mechanisms may help improve our understandings on fault zone dynamic processes. This article reviews research progress on slow slip and earthquakes in the last decade. Crustal motion and tremor activities associated with slow slip and earthquakes have been investigated extensively, mainly involving with numerical modeling of slow slips and locating slow earthquakes. On the other hand, debates have been going on about the locations of slow slip and earthquakes, the relationship between them, and the mechanisms produced them.
