Thank you for starting this thread. In my opinion, this topic is way underdiscussed, just about everywhere. I am so sick of people saying that it is
natural & normal. It may be natural, but it is not normal. Otherwise, they wouldn't be so shocking when they're heard. We all know what trains,
thunder, & fireworks sound like. These are different.
I have experienced the "sound phenomena" a few times, but in a couple of different ways. In August & September of 2011, during & after earthquakes
& they were the "booms", and a month or so ago, and it was the "trumpet" sound. In August, with the quake, it woke me up from a dead sleep,
thought someone was in our house & had slammed our basement door shut violently. Made my husband check the house. Nothing. A couple of weeks later
in September, heard them and they made my whole street shake, setting off every car alarm & rattled glass jars in our pantry. They were very, very
loud booms, like cannons being shot off, but without a lot of echo. Preceding the booms, my dog was cowering and whining about 30 minutes before it
happened and then started peeing in the corners of rooms, so I knew something was up. I emailed the USGS and they claimed that there wasn't a quake
or any sort of geologic activity and that I was probably feeling a 1.9 quake 180 miles to the south of me. Now, how does that make sense?
A month or so ago, I posted here about the "trumpet" sounds. I thought the booms were scary, but the trumpet sounds made all of my hair stand up on
end. The eeriest part about that was that at points, the sound was such a low pitch that my ears were vibrating as if still picking up sound, but the
frequency was so low, i couldn't actually hear it. At that point, my dog start barking wildly and every dog up and down our street was going nuts.
My daughter heard it, my husband heard it, but when I contacted our local PD, they said they hadn't received any calls. They did, however, check
into normal sources of sound and said that they couldn't find a reason for it and that no one in our county even had a drilling permit. It was a
very foreboding feeling, like a message or warning. I know that sounds bizarre, but if you heard it yourself, you'd understand
I've also been seeing bright blue flashes of light pop off now and again and the weirdest cloud patterns you've ever seen, form right before your
eyes. Orange-pink clouds popped up today in the midst of "normal" clouds while walking my son to school. My cell has been handy on these walks,
documenting what I've been seeing, thankfully, so I know I'm not crazy.
I think--believe--that the booms, trumpet sounds, weird sky phenomena, sinkholes, quakes, just like you said, are ALL RELATED.
