An FBI manhunt is underway in New York over potential terror concerns.
A blast shook homes miles away and created a crater in the sand in New York’s Long Island.
Police received about 30 phone calls to 911 about the explosion.
It occurred around 11 a.m. Sunday on the uninhabited island called Fox Island. It’s located off the town of Babylon.

“Obviously our department is concerned as to why someone would detonate a device of this size and magnitude on an uninhabited island,” Suffolk County police acting Commissioner Stuart Cameron told reporters.
“So we definitely want to find out who did it,” he continued.
“If you are the person responsible for this detonation, I encourage you to come forward and identify yourself to our department so we can find the root cause of this incident and allay any concerns for the public.”
You can report tips by calling 631-852-6024 or anonymously to Crime Stoppers at 1-800-220-TIPS.
More from Fox News:
Marine Bureau officers located a crater – about 4 feet wide by 2 feet deep – on the north side of Fox Island that appeared to have been created when the unspecified device detonated. Suffolk County police’s arson section detectives are seeking information about a vessel seen fleeing the area around the time of the detonation – which Cameron described as a 23-foot-long boat with stripes.
An aviation unit helicopter also was deployed above the scene.
“We do know that when people produce homemade explosives, very often they want to test those explosives to make sure they function as intended,” Cameron said, “so that is one of our concerns, and that is why we want to determine what transpired yesterday morning.”
In statements to Fox News Digital Monday, a Suffolk County police spokeswoman acknowledged “terrorism is always a concern because people do test devices before using them.” She confirmed the department is investigating alongside the FBI Joint Terrorism Task Force.
Fox News Digital followed up with Suffolk County police Tuesday morning about whether any possible persons of interest or suspects have been identified on the third day since the explosion.
Babylon Town Supervisor Rich Schaffer described hearing the explosion Sunday from his home about a quarter-mile from the Great South Bay. He said Babylon Public Safety was also overwhelmed with calls about the blast on Fox Island, where duck hunters and recreational boaters sometimes stop from Bergen Point. Lindenhurst Mayor Michael Lavorata described the island as “off the beaten path,” admitting at Monday’s press conference, “I never even heard of it before yesterday.”
