Del City :IT FELT LIKE IT LASTED ALMOST 2 MINUTES FROM START TO END. I THOUGHT SOMEONE WAS SHAKING MY HOUSE AND IT SCARED MY DOG AND MYSELF. THE DOG WAS LOOKING OUT THE WINDOW AND I WAS SCARED TO OPEN MY DOOR. AFTER A COUPLE MINUTES IT STOPPED I LOOKED OUTSIDE TO SEE IF OTHERS WAS OUTSIDE. IT WAS AFTER 2AM. I DIDN'T KEEP THE DOOR OPEN LONG FOR FEAR IT WASN'T A EARTHQUAKE. I WAS SHAKING UNTIL I CALLED THE POLICE AND THEY TOLD ME IT WAS FOR SURE EARTHQUAKE. VERY SCARY
Edmond:everything in my house was quiet and i thought a car had ran into my garage doors it was so loud. then i noticed my whole house swaying like it was on a waterbed. this happened for 30 seconds there was a very low pitched rumble and my house felt as if it were swaying back and forth 6 inches each way. after it was over every window blind was smacking against the window and my 30 gallon aquarium was sloshing. that was very frightning. my wife felt one here last year but i wasnt here that day.
Cleveland: My husband and I were watching tv in bed, and everything started shaking, the windows, the bed, the floor. Being in oklahoma, we thought a tornado had started hitting the house, it was shocking to have felt that, never imagined feeling a quake so well in oklahoma, what an experience!
