"Boom" remains a mystery across Southern Arizona

TUCSON - Emergency agencies and even our KVOA newsroom was slammed with calls from people wanting to know about a suspicious sound Wednesday evening.

A loud "boom" or "explosion" was reported between 7:40 and 7:50 and has since gone unexplained.

News 4 Tucson spoke with Pima County Sheriff's Department, Tucson Police, Tucson Fire and Davis-Monthan, and Northwest Fire. None could confirm a source for the noise.

The Pima County Sheriff's Department also contacted agencies other agencies including nearby mines, the Pinal Army National Guard, Tucson International Airport, Southwest Gas, El Paso Gas, TEP, even Luke Air Force Base west of Phoenix, to no avail.

A real-time look at the USGS map of seismic activity showed nothing in Arizona.

There have been no reports of any damage.
