Homeowners near 35th Avenue and Pinnacle Peak Road say there has been a mysterious rattle that is happening more consistently and frequently. "It was just a jolt at first and we'd feel it like 2 or 3 times out of the year," said Timothy Jackson. "As of yesterday, it was about 20 times every hour, just a steady shake."
Timothy has videos of his windows rattling during one of the episodes. He said he built his home in 2000 and the shaking started about five years later--but it's never been this bad.
"It rattles in the house but not only in the house, but outside it sounds like someone is jackhammering," said Kelly Jackson, Timothy's wife. "It's very unusual, but when it happens it really does scare you because you don't know if your windows are going to break, your house going to drop, you just don't know what it is."
The Jacksons said some walls in their house have also started to crack, as well as a few spots outside.
