After earthquakes centered in New Jersey rattled parts the NYC area twice in less than two weeks, a seismologist says it's unlikely a sign of things to come.

A relatively small, 2.7-magnitude earthquake struck near Hillsdale in northern New Jersey, according to the US Geological Survey.

A second minor earthquake has rattled the New York metropolitan area within several days. The 2.7 magnitude quake struck Tuesday afternoon near Hillsdale, New Jersey, northwest of the Bronx.
