UPDATE: Earthquake, Aftershocks Rock Millburn (What To Know)

MILLBURN, NJ — An earthquake and several aftershocks rocked the East Coast on Friday, and yes – they were felt in Millburn.

A magnitude 4.8 earthquake was detected with an epicenter seven kilometers north northeast of Whitehouse Station in New Jersey, according to the United States Geological Survey (USGS), which monitors earthquakes. See Related: Earthquake Rocks NJ, PA, NYC

Reports of buildings shaking began about 10:30 a.m. and lasted for approximately 30 seconds. The shaking was felt as far as New York City and Philadelphia. A series of aftershocks followed, including a 4.0 magnitude aftershock around 6 p.m.

Millburn school officials said they were aware of the earthquake.

"We are aware of the tremors felt locally today," a message from the district stated at 10:55 a.m.

"All schools have been inspected, and there is no damage or any other concerns," school administrators added. "The school day is operating as normal. We will be monitoring the buildings for any issues throughout the day."

Meanwhile, Millburn township officials shared the following safety advice for local residents:

• Be on the alert for several strong aftershocks or earthquakes. Be careful; aftershocks may cause additional damage to weakened buildings.
• Use a flashlight, not a candle. Sparks, open flames, gas lanterns, or cigarettes may cause a fire or explosion if there is a gas leak.
• Check buildings for structural damage if you must go inside. The primary earthquake could cause internal structural damage. An aftershock, although usually milder, could cause more damage. Look for severe cracks.
• Check water supply, food storage, and first aid supplies. Carefully open cabinets. Be alert for falling objects.
• Confine pets, as they may become more nervous after an earthquake. Contain them so they don't get away and hurt themselves or others. Make sure they have food; water; a sanitation area; and a safe, dry place to sleep.
• Turn off your utilities if you suspect damage to your water or gas line and contact your utility provider.
• Check your home's foundation for any potential damage before going inside.
• If you are without power, smell gas, or need gas and/or electric service, please call PSE&G at 1-800-436-7734 or the 24/7 Emergency Line at 1-800-880-7734.
• New Jersey American Water can be contacted at 1-800-272-1325

Nearby in Essex County, a first grade teacher from Maplewood recounted her classroom's experience.

“Around 10:30 we heard a rumbling and there was a shaking vibration,” she told Patch in an email. “The kids were asking what it was and we thought it was some sort of construction going on, may-be drilling. One girl who used to live in California said she thought it was an earthquake but we all said no way, including myself ... I couldn't believe it was actually an earthquake.”

Earthquakes in the eastern United States are infrequent – but not unexpected, the USGS says. Since 1950, there have been 40 other earthquakes of magnitude 3 or higher within 250 kilometers of Friday’s earthquake. See Related: Here's What Caused Earthquake That Shook NJ, Experts Say
