What caused it? According to the USGS, the earthquake was the results of faulting at shallow depths in the Earth’s crust.

“Although this event did not occur near a plate boundary, such ‘intraplate’ earthquakes can and do occur,” the USGS stated. “While this earthquake is relatively small globally, earthquakes of this magnitude are commonly widely felt in the eastern United States because of efficient seismic wave propagation in the region.”

“Weak” and “light” impacts were felt across North Jersey on Saturday night, including Bloomfield, where dozens of people lodged reports with the USGS.

“Yep, I felt it too,” Bloomfield Mayor Jenny Mundell reported. “Looks like we just had a 3.0 magnitude earthquake.”

Other comments about the quake from Bloomfield included:

• “I believe we just had a mild earthquake … we felt shaking in the house, Bloomfield.”
• “Earthquake in Bloomfield … did anyone feel that?”
• “Wow! Just had an earthquake in Bloomfield NJ!”
• “Earthquake in Bloomfield”

Residents of other nearby towns in Essex County also reported feeling the quake. As seen online:

• “We just experienced an earthquake about 15 minutes ago in Montclair NJ, if I'm not mistaken. Never felt or heard anything like it. A loud thump bouncing the earth, then a rumbling but not like thunder. Almost like the biggest truck in the world hitting a pothole.”
• “Caldwell, NJ my house shook.”
• “Just had [an] earthquake here [in] Nutley … thought something hit the house.”
• “We just had an earthquake [in Newark], y’all.”
• “We had an earthquake here in New Jersey … felt it in Cedar Grove, West Orange … Praying.”
• “Anyone else in Cedar Grove just feel their house shake? So weird!”
• “Earthquake in Verona … The place groaned and shook. Even my cats picked their heads up and looked around.”

The USGS reported that 43 other earthquakes of magnitude 3.0 and larger have occurred since 1950 within 250 kilometers of last weekend’s earthquake.

Over that time period, the largest was located near Tewksbury in April 2024, which reached a 4.8 magnitude. That earthquake was widely felt across the northeastern United States, the USGS said.
