Anthony Spinelli, who police said bought and detonated around 80 pounds of the explosive Tannerite at the party, turned himself into the Kingston Police Department, according to a statement sent to CNN.
After Kingston police arrived, the partygoers admitted the explosion had been part of a gender reveal party and later told a detective that they’d chosen the quarry because they felt it was a “safe location” to detonate the explosives, police said.
But the detonation triggered tremors that some neighbors who lived near the quarry believed came from an earthquake, CNN previously reported.
After a Kingston police investigation found that the explosion hadn’t caused “additional property damages,” Spinelli was charged with disorderly conduct “due to the fact that he caused public alarm,” police said in the statement.
CNN has made repeated attempts to reach Spinelli and hasn’t heard back. There is currently no attorney information available for Spinelli, according to the New Hampshire Judicial Branch spokesperson.
Kingston police didn’t report any injuries from the explosion.
Other gender reveal parties that have triggered explosions have caused significant harm.
