Residents of southern Arizona are baffled by mysterious booms being felt and heard across the southern part of the state, which have caused the ground to shake and pets to tremble. No one seems to have an explanation for the weird occurrences.
The spooky events happened two nights in a row – on Tuesday between 8pm and 8:30pm, and on Wednesday just after 3pm, according to Tucson News Now. It’s not just one or two people who have reported the strange booms, as the media outlet says it has been “inundated” with calls, emails and Facebook messages from witnesses.
