S41E:
The Role of Slow Slip Events in the Earthquake Cycle: Stressing, Triggering, and Hazard Posters


Submit an Abstract to this Session


Session ID#: 53250

Session Description:
Several recent great and large earthquakes have been correlated with slow slip events (SSE) on plate boundaries. Events in Japan, Chile, and New Zealand have preceded or triggered SSE. However, the physical interaction between fast and slow earthquakes is currenty poorly understood and many questions exist, including the relation of SSE to future large earthquakes. Understanding this interaction, either from a physical or statistical perspective, is crucial to explaining where and when future large earthquakes may occur.

Ongoing research aims to understand and model the occurrence of SSE. However, scant research specifically focuses on the role of SSE in triggering fast earthquakes. We invite contributions which investigate if and how SSE can trigger large earthquakes using such methods as physics based modeling (e.g., Rate and State Friction, seismicity simulators, stress modeling, etc.), empirical modeling or observations (e.g., ETAS, rate changes, etc.), paleoseismology or any study providing insight into this problem.
