I was in the California one on February 9th 1971 (I was 10 at the time) that was similar in size , and lived close to the epicenter , that was way scarier than this one ... but this one freaked me out the same .. with this one I had just sat down at my PC and my chair started moving ,literally right when I sat down , it felt weird , so I got up and walked into the kitchen and was looking out the kitchen window at the animals , then the next one came , and the house started swaying like you were standing in a rowboat in rough water or something .... then there was one more small one , each lasted about 20 or 30 seconds .....
Anyway , thought I would share .... I hate quakes ... I thought living here that was the last thing I would need to worry about ..... hopefully that was it for the next 30 years ........

Update: 10 pm news
They just announced on our local news they did have a similar size one in Yellowstone earlier today , not long before the one we had here , the Seismologist said they were each on a different fault , so not sure what that does as far as linking them or not , as that could be a good thing , but it is strange that 3 different faults all slipped so close together in time , they said it was felt across 7 states and up into Alberta Canada ... so it was fairly significant .....
