Abstract: The Pennsylvania State Seismic Network (PASEIS), established to monitor both natural and induced seismic events within the Commonwealth of Pennsylvania, began in 2005 with a limited number of stations and expanded to its current configuration of more than 30 stations in 2016. PASEIS data are recorded continuously and made openly available in near real time under the PE network code via the EarthScopeData Management Center. At Penn State, the data are ingested into the Earthworm software package for automated seismic event detection, location, and magnitude estimation. Earthworm results are reviewed and revised by a seismic analyst and posted to the PASEIS website. Between November 2016 and December 2024, 1305seismic events were detected and located (47 earthquakes, 4 mine collapse events, and 1254 mine and quarry blasting events).
