Md. geologists to boost seismic monitoring ahead of 'fracking'

Given that seismic activity is rare in the ancient rock of the Appalachians — and damaging earthquakes even rarer — there is only a single apparatus measuring underground rumblings within Maryland borders. But geologists are about to put another ear to the ground.

The Maryland Geological Survey, anticipating the possibility that hydraulic fracturing, or “fracking,” for natural gas in the Marcellus shale deposits could increase seismic activity, plans to install a seismometer in Western Maryland.

Geologists want to gather more data on natural seismic activity before a state moratorium on hydraulic fracturing ends in 2017 and what are known as “induced” earthquakes might begin.
