Abstract

Earthquake early warning is a relatively new technology that can provide a few seconds of life-saving warning ahead of the next earthquake you experience.  These alerts started in high hazard zones, and are now rolling-out globally, including in eastern Canada later this year.  The ShakeAlert system in the western US has been generating public alerts since 2019.  The free MyShake smartphone app has been delivering the alerts to the public and also collecting seismic waveforms in earthquakes.  We will explore the performance of the warning systems and the utility of the massive seismic datasets now being generated by alert enabled smartphones located in the homes and offices we all occupy.
