NEW YORK (PIX11) – A 4.8-magnitude earthquake that shook New York City in April displayed “peculiar behavior” that raises questions about the potential threat of future earthquakes in the region, according to researchers.
In a new study , researchers from New York’s Columbia University and South Korea’s Seoul National University investigated the earthquake that struck Tewksbury in northwest New Jersey on April 5.
An estimated 42 million people felt the earthquake , according to the United States Geological Survey. Though damage from it was mostly minor, it was the biggest earthquake to occur in the region since a 5.2-magnitude earthquake near Brooklyn in 1884 .
The April earthquake displayed some “peculiar behavior,” according to Won-Young Kim, a researcher at Columbia Climate School’s Lamont-Doherty Earth Observatory, who co-authored the new study.
When Kim and his colleagues visited the epicenter in New Jersey to investigate after the earthquake, they were surprised by what they encountered.
