884.5 km NE of epicenter [Map] / Weak shaking (MMI III) : Wasn't sure if it was an earthquake I felt. Felt table I was leaning on when sitting still next to it, and it did a shaking-vibrating motion for only 2 seconds. Looked back on the history of earthquakes near me that could have been felt to see if it could have been an earthquake that I really experienced, and it said I could have felt this one. The time aligns when I felt the table shake/vibrate. | 3 users found this interesting. (reported through our app)

Mississippi / Violent shaking (MMI IX) / vibration and rolling : PLEASE READ!!! I’ve had dreams and visions in Advance that a short time later,PLEASE don’t ignore. I just dreamt today at around 4:00 CST that a very higher Earthquake is coming. It occurs in the daytime after a lull in activity the previous night. It will begin in New Mexico and go down a fault line all the way to San Francisco. It will buckle roadways very VERY badly. The roadways in I believe San Francisco... afterward people were living in campers everywhere. I apologize any inconvenienc | 2 users found this interesting.
