New Jersey was once roughly the size of St. It was home to a fiery volcano the size of Mount St. Helens, and it was located in the same county as the newly mapped fault line.

Rutan Hill in Wantage, NJ, appears to be, and is only one of, many unidentified land formations that make up the topological face of the Garden State.

But this little mound of County Sussex was the Beemerville Volcano 430 million years ago; It was 10 to 20 miles across and spewed lava and ash for millions of years. According to geologists.

Beemerville Volcano is thought to be an extinct volcano, and all that remains is Rutan Peak and the “volcanic neck.”

“Necks”, also called “plugs”, are the solidified remains of a volcano’s piping and plumbing system and are the last impression left by an extinct volcano.

Geologists say That the volcano is unlikely to erupt for at least millions of years.

But New Jersey was shocked by a new report this week. previously unmapped fault line This also runs through Sussex County.

Education from Columbia The university’s Lamont-Doherty Earth Observatory detected the fault line on April 5, the day of a 4.8 magnitude earthquake. shook new york.

This once-in-a-century tremor revealed the structure of the fault line, which experts say could be dangerous for the Big Apple.

The fault line runs from south to north and plunges into the Earth at a 45-degree angle; This means that the echoes are sent downwards rather than towards the surface.

“There was much less damage or shaking near the epicenter than would be expected from a magnitude 4.8 earthquake, and that was something unique to that earthquake,” said study author and Columbia professor Won-Young Kim. Gothamist.

There was not much shaking at the epicenter of the earthquake in Tewskbury, but according to the research, the earthquake of magnitude 4 occurred in New York.

The April earthquake caused minor damage to 150 buildings in New York City and caused a school in Brooklyn to close its gym for repairs.
