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.
Seismic signals from our state-of-the-art Guralp CMG-40T broadband digital seismometer are available on the web at
Live Seismic Signal. The web page is updated every two minutes. The scale on the left is local time; the scale on the right is Greenwich mean time. One horizontal line represents 30 minutes, and a full screen represents one day. Alternating colors help to distinguish the lines. The vertical deflection represents the amplitude of ground motion.
An archive of digital F&M seismograms can be accessed at Seismic Archive. Separate seismograms can be seleected for either the vertical (BHZ), north-south (BHN), or east-west (BZE) components of ground motion.
Earthquake epicenters can be located using data from three or more seismographs. Our seismograph is not calibrated for determining earthquake magnitudes.
F&M is a member of the Lamont-Doherty Cooperative Seismographic Network, www.ldeo.columbia.edu/res/pi/LCSN/
