Loud BOOMS in Utah...apocalypse started?!?!?!

Reports of loud booms during the night. Still waiting for the sun to come up. :scared:

My 3 theories:

1. Sonic booms from jets flying overhead (which isn't that common since jet speeds are restricted in urban/populated areas - I think they have to stay under mach 1 - the speed of sound)

2. If the booms were in SLC, then another culprit may be Kennecott's Bingham Canyon mine. After production drillholes are loaded with explosives, in almost every case they are shot. Residents in West and South Jordan and Jordan Commons often complain about the blasts coming out of the open pit mine. The cause of the noise is actually called air overpressure - it's not very well understood, but basically it's when the sound waves coming off the blast travel high into the air and then are redirected back to earth in an arc. Where that arc meets the earth is where you'll hear the concussive blast, and in some cases residents have reported broken windows.

Usually the blasts occur during the day, but sometimes the powder crew doesn't get the holes loaded in enough time to shoot it so they'll have to "sleep" the holes overnight. Sleeping loaded holes can be risky business because you have live holes just sitting there with a possibility for them to get accidentally touched off. In order to avoid sleeping the holes sometimes they are required to shoot the holes at night.

3. Apocalypse is upon us (hopefully). I hate it when science has to know everything all the time. :haha:

The booms were rocket testing at ATK.

Hill Air Force Base and ATK both said the booms didn't come from them. Wednesday morning, seismologists said the sound could have traveled from far away. -ksl.com

Alright, you guys weren't hearing things.

"Since the temperature increases with height, the speed of sound also increases with height," wrote Dr. Daniel A. Russell (http://www.acs.psu.edu/drussell/Demos/refract/refract.html), a professor of acoustics at Penn State. "Unfortunately it's usually when you're trying to sleep that you hear things better. And if you've ever lived in a railroad town, you've noticed this before," one seismologist at the University of Utah said.


Um....no. Sounds like Doctor Danny needs to go back to high school. I thought everybody knew that temperatures DECREASE with height. This is why if you're flying with pets they may not be stored in the standard baggage compartment with all the other luggage. They would freeze to death.

From wiki:
[I]The environmental lapse rate (http://en.wikipedia.org/wiki/Environmental_lapse_rate) (ELR), is the rate of decrease of temperature with altitude in the stationary atmosphere at a given time and location. As an average, the International Civil Aviation Organization (ICAO) defines an international standard atmosphere (http://en.wikipedia.org/wiki/International_standard_atmosphere) (ISA) with a temperature lapse rate (http://en.wikipedia.org/wiki/Lapse_rate)[COLOR=#0000ff] of 6.49 K(

KSL is reporting it was B-52s.

The B-52's are LOUD. I've seen them in concert and I prolly lost some hearing. Huh? :haha:
