BUTLER - A federal environmental agency says a small earthquake has hit northern New Jersey for the second time in less than two months.

The U.S. Geological Survey says the magnitude-1.6 quake hit the Morris County borough of Butler Thursday evening.

Borough police say more than 1,000 people reported feeling the tremors. No damage has been reported.

The federal agency says earthquakes with a magnitude between 1.0 and 3.0 aren't typically felt. The agency says Thursday's quake was shallow, with its epicenter located about a mile underground.

A magnitude-2.07 earthquake also hit northern New Jersey on Jan. 2. Mahwah residents as well as those in New York's Rockland County also reported feeling that quake.
