3.1 Magnitude Earthquake Felt In Hudson Valley

FREEHOLD – A 3.1 magnitude earthquake was recorded in New Jersey on Wednesday, and the effects of it were felt across the mid-Atlantic including in the Hudson Valley.

The U.S. Geological Survey said the 2 a.m. quake was at a depth of 5.0 kilometers, or 3.1 miles, centered in the East Freehold section of Freehold Township in Monmouth County.

According to the USGS website, more than 6,000 responses were logged, saying the earthquake had been felt, including in lower Westchester and Rockland counties and in the Catskills (see map below).

"I was sleeping and it woke me up," Marie Greenberg of North Tinton Falls told Patch. "I felt myself move and my house shook. I thought a truck or car hit my house. I checked my entire house and looked outside. It was scary."

The Monmouth County County Sheriff's Office reported that the quake was felt throughout Monmouth County and beyond, and was in very close proximity to the 911 Communications Center on Kozloski Road.

That office received 125 calls within a half hour period. There was no interruption of service or damage and no injuries were reported, the sheriff's office said.

The Freehold Police Department told NBC10 that quake felt more like “the floor dropped out” rather than a wavy motion.

The National Oceanic and Atmospheric Administration did not report any tsunami activity off the East Coast.

It's among the biggest to affect New Jersey since a 3.0 earthquake in April 2019, which hit Long Island, could be felt across the state. It's also among the biggest since a 5.8 earthquake in 2011 was felt up and down the East Coast, and caused damage to hundreds of homes and structures.

Earthquakes happen when there is movement below the Earth's surface on fault lines. They can occur anywhere in the US and usually last less than a minute, according to FEMA.

A small earthquake and two aftershocks centered in Putnam County shook the Hudson Valley Feb. 7, 2018.

Also recently in the Mid-Atlantic region, two small earthquakes rumbled the Goochland, Va., area on Nov. 9, 2018, the same region where the 5.8 earthquake in August 2011 originated and caused damage the Washington Monument in Washington DC.

The 5.8-magnitude quake on Aug. 23, 2011 alarmed millions along the East Coast including New Rochelle. "Tens of millions of people all over the East Coast and southeastern Canada suddenly felt the earth shaking from the largest earthquake in that area since the M5.8 earthquake in 1944 near Cornwall and Massena, New York," the USGS said.

When the earth stopped shaking, more than 148,000 people reported their experience of the earthquake on the Did You Feel It? website, representing an area occupied by one-third of the U.S. population.

That quake also damaged the National Cathedral and the Armed Forces Retirement Home in Washington DC, as well as caused minor to major damage to almost 600 residential properties.
