I have been hearing these loud booms in the valley when I moved to the east side next to the cannery. One just went off about 25 minutes ago. It is extremely loud and can shake the house windows and the boom can be heard echoing off into the distance. I have lived in anthem/Henderson for years and never heard this. I moved to the east side in 09 and have heard the exact type of deafening booms at least a dozen times or more and it is always late at night. Just wondering if others have figured out what is causing this sounds I am getting sick of it and it's one reason we are planning on moving out of east Vegas. Thanks.
