Hi at first I thought maybe it was open windows shaking my doors and windows, it does get pretty windy where i live in california.
then it happened two more times.
I went onto facebook and there are FIVE posts about this from friends i have from up to 30 miles away.
I live in the central coast of california, if you go to USGS you will see NO registered earthquake activity.
My only other thought was a sonic boom, but how could one happen 3 times(one of my friends reported 5 of these)
they were short and lasted a few seconds, almost explosion like
