Hundreds of people across the Bay area say they got a scary wake up call this morning.
Many say they woke up to shaking windows and a loud noise, but no one knows what caused it.
“The house literally shook, said Polk County resident,” Arlene Sambursky
Others heard it and called 911.
“We heard this big big bang!,” said one 911 caller.
“The only way I can describe it is two loud tremors," a 911 caller told an operator. "I went outside to check and see if a tree fell because it was so loud.”
The rest took to social media.
One viewer said she thought her front door was slamming. Another said she thought her husband fell in the tub.
The noise was so loud people from Polk to Pasco County dialed 911 to report the suspicious, earthshaking wake up call.
Merrill Sambursky was one of those callers.
“I’ve been in a couple earthquakes out in California so when I felt the house shake I said wait you’re not supposed to get earthquakes here but who knows the way everything’s going lately you don’t know,” he said.
The operator offered up a suggestion of what could have caused the suspicious shaking.
“Sometimes when they have the farming in the area they set off like a cannon to scare the birds away,” said the 911 operator.
Could it have been a bird flying a little higher in the sky? Like an airplane moving faster than the speed of sound? Causing a sonic boom?
Nearby air force bases say they can’t confirm that. Retired air force police officer, Sambursky says neither can he.
“This one this morning was no sonic boom,” he said.
Then just what was it? It’s an answer we may never know for sure.
“And the mystery continues,” Sambursky said.
