Heard them twice here in Colorado since 8/23, day of the much-reported quake last month (I think that was the day). That day, heard one @ 5am, I
thought that someone was in my house, woke my husband because it sounded like such a loud slam or boom, coming from what I thought was downstairs.
Shook my bedroom floor & bed for at least 5 seconds. Husband took a look, nothing, no one up. Turned on the news a few minutes later and it was all
about the quake @ midnight. Last week, heard it again, this time immediately preceding a small swarm of lo-mag quakes in the same place, some 150
miles or so to the south of me on the CO/NM border. This time, it sounded like a loud gunshot, but set off all the car alarms on my street and shook
glass jars of spaghetti sauce in my pantry. Tried to report it to the USGS, inquiring as to how such a small quake could possibly have that effect at
my location, as no other quakes were reported. I was essentially told that if I felt the 4.0 two hours after the one I believe I felt, then that's
probably what I felt, but if I hadn't (which I didn't), then that was probably not a quake, and USGS wouldn't turn on "Did you feel it?" for that
quake. A minute or so prior to the loud bang and shaking, we saw a bright ball of white-blue light quickly appear and disappear in the sky just to
the west of us. Figured it was "earthquake lightning."
So, I do not know what this is, but it isn't just NC and it seems to be either seismically related or it causes some sort of seismic activity by
Would love to hear from other Coloradans to see if anyone else has felt it out this way
