Monday’s incident marked the strongest earthquake in the northeast U.S. since last year when a 4.8-magnitude earthquake hit New Jersey in April — the strongest to hit the region in more than a decade, according to NBC News. There is currently no tsunami threat in New England, according to the U.S. Tsunami Warning Center.

People across the region felt a 3.8 magnitude earthquake that was centered off the coast of Maine in York Harbor. So how rare is such an occurrence in New England?

An earthquake centered off the coast of Maine rattled the region Monday, causing light to moderate shaking in the state, as well as in parts of Rhode Island, Massachusetts, New Hampshire and Connecticut.
