Scientists have a new working theory when it comes to the source of an earthquake that rattled New Jersey in 2024, with a previously unknown fault line to blame.⁠ ⁠ For years, the working theory was the quake was caused by the well-known Ramapo Fault. But now research suggests that wasn't the case. It instead came from an entirely different fault that had long gone undetected, which has since been named the Mountainville Fault.⁠ ⁠ #newjersey #nj #earthquake #nbc4ny
