Earthquakes in my city and lots of them.....in 3 days..anyone feel?

Question

Seems that in the past 3 days there have been 13 tremors and aftershocks. We don't really get them often here in southern Indiana. One scared the willie wonkers out of me. It was only a 5.2 but I was sleeping and ilt woke me up startled. You know how that goes. But now every little sound and motion makes me think there is another one about to happen. Anyone else around here feell all these quakes in the past couple of days? What do you think causes quakes?

Answer 1

I'm too far west, in Wyoming,  to feel those particular quakes, but yes, quite a few aftershocks continue.  

Earthquakes are the result, basically, of pieces of landmasses moving and grinding against each other.  The land masses (plates) get jammed at various points and the pressure builds as the land masses still want to move.  Eventually the jam snaps free, and the energy released when that happens radiates outward, which is felt as an earthquake.
