  • Payson - Crazy
  • Santaquin, UT - Felt maybe 3 to 5 seconds of shaking
  • Santaquin - shook my bed and woke me up
  • Payson - Felt this at !2:12 AM
  • Payson - Just watched my house sway...so freaky!
  • Santaquin - We heard the noise first, a loud rumbling like a large semi truck loaded with rock dumped it outside our windows, our house shook hard. Sounded almost like a close explosion. Woke neighbours in the neighbourhood. People outside looking around. No back and forth movement, just a loud noise and a shaking, more up and down, not side to side. (I'm from California, San Andreas Fault area...ARRRGH
  • Elk Ridge - Woke us up at 12:12am also.
  • Santaquin - Woke me right up, loud sound, shaking for a couple of seconds. Husband slept right through it!!!
  • Santaquin - Just had gone to bed when it felt like a big dump truck came by and rattled the house, but I have never felt an earthquake. So I asked my husband about it and he said "You just felt your first earthquake."
  • Santaquin - Heard a loud rumbling outside, and then felt a wave of powerful shaking pass under the house from one end to the other. As it passed under my bed, it felt like the ground was lifting up under me.
  • Genola utah - Asleep then at12.12 am I awoke to a loud roar like a freight train as soon as realization set in the bed shook violently along with the house and everything else. I ran through the house checking on my children, then outside to check the stones in my rock walls.
  • Santaquin - Heard things rattling on the dressers etc.
  • Santaquin - I was sleeping, woke to what I thought was a large loud heavy truck rumbling for a few seconds then there was a large SMACK, like that truck had hit the house (that's what I thought)then realized it was and EQ. Dad only heard the smack not the rumbling. 18 year old woke up, the other 4, 16, 13, 9,7 slept through it. Nothing fell, no damage, hazard hunt going on today.
  • Salem - Woke up house shaking, furniture shaking, wife slept through it Checked on kids they slept through it, went outside to see what it was heard it was an eq this am on the news

  • Santaquin - The shaking woke me up around 12:14 a.m, I heard a loud rumbling noise and the stuff on my dresser was trembling. That was my first earthquake experience, hubby slept right through it!
  • Elk Ridge - I was up working late. It seemed more like a sonic boom without the boom, or a really strong, really micro"burst" of wind that hit the house all at once, rattled the roof and walls for about 4 seconds and was gone. Didn't displace anything. Nothing like the Oregon Scott's Mills 5.6 earthquake of 1993 that sounded like a freight train before it hit and rippled the walls and ceiling for long enough to tell what was going on.
  • Woodland Hills - There was a definite ((SHAKE))and shift felt in the house, both on the main floor and on the 2nd floor.
  • Salem - Heard a weird "boom" sound and then my laptop started wiggling back & forth on my lap & the ground under my feet started going up & down really fast like Jello jiggling. Kind of freaky.
  • Spring Lake - I was awoken by a few windows rattling.
  • Woodland Hills - I was getting ready to go to bed, and at 12:12 am I felt the house shake a little. It felt like there was thunder outside, but I knew that it was a small earthquake.
  • Payson - Was lying away when the house started shaking and rumbling. Didn't last very long. I wasn't sure what it was. I thought it must be an earthquake but I wasn't sure.
  • Woodland Hills - I felt one moderate shake that caused water pooled on the roof to start dripping. Felt like something very heavy had fallen nearby.
  • Spring lake Utah - Woke members in household up. Vibrations
