The following seismic stations have recorded disturbances. To retrieve data click on the station and then click on the data file. All data files contain information recorded at 200 Hz , or 200 data points per second.
All data points represent displacements in millimeters .
Horizontal data are movements in a plane tangent to the surface of the earth. North is a positive displacement. 39.01 N 77.03 W. Williamsport, MD 39.6 N 77.82 W. Accident, MD 39.62 N 79.32 W. Crofton, MD 39.0 N 76.69 W. IndianHead, MD 38.6 N 77.17 W. Work together to determine the location and Richter magnitude of this earthquake. Make damage estimates if necessary. It is possible to download all the data yourself, but we want to work together on this project.
