People in and around Southport and Oak Island heard and felt a boom Tuesday night that some said shook their homes.

Calls and emails started pouring into WECT's offices after the loud noise, which happened around 8:15 p.m.

One Brunswick County official said in a text message it was probably the Seneca Guns, but officials at Military Ocean Terminal Sunny Point advised Brunswick County dispatch, which received numerous calls about the boom, that they were holding a training exercise Tuesday evening.

According to the Deputy to the Commander at MOTSU, however, there were "no training exercises, detonations or explosions at Sunny Point" Tuesday night.

"We do not conduct training exercises here at Sunny Point," said Steve Kerr, Deputy to the Commander at MOTSU.

Kerr said he spoke with staff members and nobody contacted Brunswick County EMS saying they had conducted training exercises.

According to the First Alert Weather Team, no sonic boom-like activity was spotted on the radar during the reported time frame.

Some people who commented on a post on the Southport NC Traffic Reports Facebook page mentioned the Seneca Guns, but several said Tuesday's noise was different.
