Conference Objectives and General Description

Slow slip phenomena, which include slow slip events (SSE), tectonic tremor (TT), low frequency earthquakes (LFE), and very low frequency earthquakes (VLF), have now been observed in most subduction zones with dense geodetic and seismic networks and along some major crustal faults. Slow slip processes are now viewed by the seismological community as a crucial aspect of fault mechanics. Previous conferences dedicated to slow slip have primarily focused on the Japan and Cascadia subduction zones. However, new detailed studies in subduction zones in Alaska, Costa Rica, Mexico, New Zealand and fault zones such as the San Andreas and on faults beneath the Hawaiian volcano complex are providing additional observations.

Moreover, the slow slip community is now beginning to move beyond just observational studies, as many new datasets and modeling studies in the last few years have begun to shed light on the physical processes that produce slow slip. These recent efforts towards understanding the processes make this Chapman Conference very timely.

This conference will examine these phenomena globally and promote discussion and interaction by bringing together scientists working on slow slip in all places where they are observed. Abstracts are encouraged based on the following topics:

  1. Observations of slow slip phenomena
  2. Fault structure and physical conditions where slow earthquakes are observed
  3. Slow earthquakes and their relationship to large earthquakes and seismic hazard
  4. Models and laboratory experiments
  5. Improving observational methods for the analysis of slow slip phenomena

The conference is being held at the edge of the zone of the largest SSEs observed to date in the world (Mw = 7.5) that occur every 4 years with durations of 6 months to a year. Unfortunately, we will miss the next SSE, which will occur in 2018-2019. The SSEs here appear to extend updip into the Guerrero Seismic Gap just to the east of Ixtapa.
