did anyone feel?
Posted in the Lancaster Forum
did anyone feel something similar to a sonic boom,coming from underneath the ground at around 11:30? the reason why im asking is because im concerned about it, for usually a sonic boom is felt all around, the windows and the walls shake and this time it was just underneath.
Nothing on the USGS Earthquake Map ( http://earthquake.usgs.gov/earthquakes/recent... ) today for the Lancaster/Palmdale area. It was most probably a sonic boom (maybe "ducted" by the atmospherics of today's storm system). Another possibility... do you have any quarry, mining or road building operations within a few miles? Sometimes when they blast, the shock wave can travel surprisingly far.
