The first report on the Dillsburg earthquake swarm has been released. This report is the summary of the findings from the Columbia University portables that were in the area October-December, 2008. Data is still being complied from portables placed last summer in the area. Jeri Jones is looking at a connection between the groundwater, rainfall and the tremors. If you feel any tremors, please contact him as you have in the past. Tracking these tremors is still important, especially since he is correlating them with rainfall.
The website to read the report is www.dcnr.state.pa.us/topogeo/openfile/dillsburg.aspx.
