2.2 Magnitude Earthquake Shakes NJ

CALIFON, NJ — A 2.2-magnitude earthquake awoke some New Jersey residents early Wednesday morning, marking the latest to rattle the area since April 5's 4.8 earthquake.

The United States Geological Survey said the quake struck around 1:44 a.m. about 5 km east of Califon.

This latest earthquake marks the sixth to rattle the Garden State during the month of July. Five were reported in the Califon area and one near New Egypt.

Take a look at the earthquakes that shook New Jersey in July:

• July 3 - 0.9 magnitude location 6 km east southeast of Califon
• July 6 - 2 magnitude location 1 km east of New Egypt
• July 13 - 1.2 magnitude location 7 km southeast of Califon
• July 19 - 0.8 magnitude location 4 km east southeast of Califon
• July 23 - 1.2 magnitude located 6 km east southeast of Califon

There have been 182 earthquakes reported since the 4.8 earthquake was detected on April 5 around 10:23 a.m. with an epicenter near Lebanon, according to the USGS.

The strongest aftershock occurred near Gladstone at 3.8 magnitude about 6 p.m. on April 5, the USGS said.

Since then, aftershocks have ranged in magnitude from 2.9 to 0.5 in New Jersey.

Earthquakes are less common on the eastern than western edges of the United States because the East Coast does not lie on a boundary of tectonic plates. But 13 earthquakes of magnitude 4.5 or stronger have been recorded since 1950 within 311 miles of April 5's temblor, the USGS said.

The strongest was a 5.8-magnitude quake in Mineral, Virginia, on Aug. 23, 2011, that jolted people from Georgia to Canada.
