1200 west diamond blvd. Spc 1212 / Strong shaking (MMI VI) : House was rocking back and forth, lights were flickering, I had a panic attack and almost fainted because of the fear I was going through, my 3 babies were terrified , it was super strong and scary for sure, we have minor cracks on the walls, things fell down and broke, I’d upload photos but couldn’t take pictures, my first instinct was to grab my 3 children and run outside the house with them, I feared the mobile home would of collapse on them.
