Near real-time Cascadia slow slip events

Abstract

Slow slip events (SSEs) play an important role in the seismic cycle, participating in the moment budget of active faults. SSEs can be monitored via space geodesy (e.g. Global Navigation Satellite System, GNSS). One of the major challenges when studying geodetic data is that they record the deformation due to many active sources (e.g. tectonic, hydrological, volcanic and anthropogenic). Here I present a procedure to automatically reconstruct the spatiotemporal history of SSEs in the Cascadia subduction region. The solution is updated daily and made publicly available. These results constitute the base for future prospective SSEs forecasting experiments.
