Scientists are investigating what factors caused the tsunami-like waves that struck the East Coast, including the Jersey Shore, earlier this month.
The tsunami-like waves that battered the shoreline at more than 30 spots along the coast, from Puerto Rico to Rhode Island, on June 13 may have been a tsunami, the National Oceanic and Atmospheric Administration said Tuesday.
"This event produced a tsunami that was recorded at tide gages monitored by the West Coast/Alaska Tsunami Warning Center," the agency said in a statement. "The tsunami was observed at over 30 tide gages and one DART buoy throughout the Northwestern Atlantic Ocean."

In New Jersey at Barnegat Inlet, a fisherman reported seeing a massive, 6-foot wave on June 13 along with high winds and strong thunderstorms. The wave reportedly knocked two people off a jetty and into the water where they were then rescued.
"The event occurred in close conjunction with a weather system labeled by the National Weather Service as a low-end derecho which propagated from west to east over the New Jersey shore just before the tsunami," NOAA officials said.
The last tsunami to hit New Jersey was in 1931.
Mike Angove, head of NOAA's tsunami program, said his team is working to find out whether a storm surge or a landside off the continental shelf caused the tsunami, CBS News reported.
News that a tsunami may have hit the East Coast sparked strong reactions on Twitter.
