Its famous summer residents sent their prayers to those affected.
"Sandy destroyed Seaside—our second home," Nicole "Snooki" Polizzi told MTV News in a statement. "It's devastating to see our boardwalk and favorite spots ruined. My prayers go out to everyone affected by the storm."
Huge piles of sand choked the streets blocks from the beach on the narrow barrier island as construction vehicles entered the ghost town Wednesday.
Police Chief Thomas Boyd described the island scene as one of "total devastation."
An Associated Press photographer who went by the house used to film "Jersey Shore" said it appeared to have come out of the storm unscathed.
Appearing Tuesday on "The Tonight Show," Jenni "JWoww" Farley was asked by host Jay Leno about the house she owns with her fiance, Roger, in neighboring Toms River.
"Fixable, I want to say. It's really, it like hurts the heart a lot. It's really kind of devastating," she said. "But as long as like my dogs, Roger's safe, my friends are safe, we're just all without power."
Vinny Guadagnino told MTV that Seaside Heights had become his second home, while Paul "Pauly D" DelVecchio sent thanks to the "heroes" who were working to help. Sammi Giancola called the impact "devastating."
Guadagnino tweeted that the New York City borough of Staten Island, where he lives, "looks like war zone" and posted a picture of a downed tree.
He, Farley and DelVecchio asked their Twitter followers to donate $10 to the American Red Cross by texting REDCROSS to 90999. Polizzi also said she would donate but was more true to form: "Ugh trying to change my son's diaper while holding a flash light is not easy," she wrote from East Hanover, using the hashtag "nopower."
