Near Real-Time Cascadia Slow Slip Events

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). We present a procedure to automatically reconstruct the spatio-temporal history of SSEs in the Cascadia subduction region in near real-time. The solution is updated daily, and the last update refers to the day before yesterday because of latency time to retrieve the rapid solutions. The experiment has been running since August 2024. Given the duration of days/weeks of slip episodes, these results open the door to prospective forecasting experiments rather than retrospective ones. First forecasting results will be presented and discussed.
