"Fifteen seismographs placed in forests, farms and backyards
across northern Connecticut picked up the vibrations of a 7.9-magnitude
earthquake in Papua New Guinea on Jan. 22.
"That information arrived from 200 kilometers - 124 miles - under the Earth's surface, deep within the planet's upper mantle,
below its crust. It will help geologists at Yale University and
elsewhere better understand what lies underneath Connecticut. It will
also help explain why the supercontinent Pangea split about 200 million
years ago, forming the Atlantic Ocean and creating the continents of
North American, South America and Africa.
"The data might also help explain why 'the Atlantic basin
is opening and getting bigger and the Pacific Ocean basin is getting
smaller' and why the continents rimming the Pacific are likely to bash
into each other and form a new supercontinent hundreds of millions of
years from now, according to Maureen Long, a Yale professor of geology
and geophysics who is overseeing the Seismic Experiment for Imaging
Structure beneath Connecticut, or SEISConn."
A recent Middletown Press article profiled various aspects of the work of SEISConn.
