Scaling Relationships Of Source Parameters For Slow Slip Events, Haiying Gao, David A. Schmidt, Ray J. Weldon Ii

Haiying Gao

To better understand the physical mechanisms of slow slip events (SSEs) detected worldwide, we explore the scaling relationships of various source parameters and compare them with similar scaling laws for earthquakes. These scaling relationships highlight differences and similarities between slow slip events and earthquakes and hold implications for the degree of heterogeneity and fault-healing characteristics. That static drop remains constant for different-sized events as is observed for earthquakes. However, the static stress drop of slow slop events is within a range of 0.01-1.0 MPa, 1-2 orders of magnitiude lower than that found for earthquakes, which could be related to the …
