Slow fault slip plays a fundamental role in releasing tectonic stress and modulating seismic hazard across various tectonic settings, including subduction zones, transform boundaries, continental fault systems and collision margins. Decades of observations have shown that slow slip is often associated with seismic moment release (low-frequency earthquakes, tectonic tremor, regular earthquakes), outlining a continuum of moment release, from slow, distributed to seismically-observable fast, localized slip acceleration. However, these slow-and-fast slip components vary across regions, suggesting that structural heterogeneities may underpin its intriguing complexity.This session aims to explore how and why slow slip becomes seismic, to improve our understanding of the dynamics of moment release in slow-slip-prone areas. We welcome contributions building towards a comprehensive understanding of slow-slip spatiotemporal variability and interactions with seismic events, employing geodetic and seismic data, geological records, laboratory experiments and modeling, as well as emerging technologies such as machine learning and distributed acoustic sensing (DAS).
