Session ID#: 14143

Session Description:
Slow earthquakes encompass a variety of behaviors including tectonic tremor, very low-frequency earthquakes, and aseismic slow slip events (SSEs). At times, these behaviors are coincident, while at other times they are observed separately. Slow earthquakes may increase stress loading on the seismogenic zone and hold clues to a more thorough understanding of regional seismic cycles. Studies have indicated slow earthquakes to be a potential precursor of megathrust earthquakes, but the necessary linkage remains unclear. Additionally, up-dip transitional zones showing evidence of slow earthquakes can rupture coseismically, producing larger tsunamis and earthquakes than previously expected.  This session aims to provide an understanding of slow slip and associated seismic phenomena, and their possible connection to large damaging earthquakes. We welcome abstracts that cover seismological, geodetic, and geological observations, seismicity catalog statistics, laboratory experiments, and theoretical modeling.
