Temple scientists have re-installed a seismometer at Temple University Ambler to monitor seismic activity along the East Coast. The seismometer recorded the 5.8 earthquake that shook the Philadelphia region in August 2011 and the 9.0 quake that caused Japan's tsunami. "We'll be watching the next couple of weeks to make sure the data's coming back clean and there'll be other seismometers on the east coast we can compare records with to make sure it's seeing good data at the right times," said Temple geophysicist Jonathan Nyquist.
