New Insights on Slow Earthquakes : from Laboratory and Theory to Observations
Session ID#: 84500
Session Description:
Tectonic faults exhibit a spectrum of failure modes ranging from aseismic creep, to slow slip and devastating earthquakes. Despite the growth in observations of slow earthquakes, our knowledge about their complex behavior is far from being complete.
We aim to bring together observations of slow earthquakes and advances in our understanding of their origin. We encourage submissions based on field investigations, laboratory data, seismic/geodetic observations and theory, and specifically those highlighting the broad range of work done to provide new insights on slow earthquakes, addressing questions such as: What physical mechanisms govern slow earthquakes? What can we learn from their spatio-temporal evolution for the seismic hazard assessment? How are they recorded in fault rocks? Can our understanding of elastodynamic rupture propagation be applied to slow slip and the full spectrum of tectonic failure modes?
We particularly encourage contributions that shine a light on the connection between slow and fast earthquakes.
