Franklin & Marshall Earthquake Seismic Station
Our seismic station is capable of detecting seismic waves generated by large earthquakes anywhere in the world. Small, local earthquakes, non-seismic events, like quarry blasts in the Lancaster area, and microseisms from the impact of high-energy waves on the continental shelf, can also be detected.
A new seismic station was installed at Millport Conservancy in Warwick Township, Lancaster County in August 2017. Prior to this installation, the station had been located on the F&M campus in the city of Lancaster.
Seismic signals from our state-of-the-art Guralp CMG-40T broadband digital seismometer are available on the web through the Lamont-Doherty Cooperative Seismograph Network. Our station code is FMMC (Franklin and Marshall-Millport Conservancy). Links to archived data can be found at the top of the page.
The current day's seismogram is updated about every 10 minutes. The time scale on the left of the seismogram is in Greenwich Mean Time (GMT). One horizontal line represents 60 minutes, and a full screen represents one day. Alternating colors help to distinguish the lines. The vertical deflection represents the amplitude of ground motion. Separate seismograms can be selected for either the vertical, north-south, or east-west components of ground motion.
