Mysterious Booms Heard Down Under

Mysterious booms, bangs and shudders have been reported on Unknown Country for years, and they continue to be a phenomenon that we monitor with a keen interest.

The unexplained noises have been heard all across the globe, including Canada, Brazil, Ukraine, Spain, South America, Russia, many areas of the United States and across the United Kingdom. Now it seems as though the booms have traveled "down under" as a series of strange "explosions" have been heard across west and north Auckland, in New Zealand.

A local Facebook page was inundated with 450 comments, reporting booms and shakes from Stanmore Bay to Stillwater. The local authorities are mystified by the noises, which began at around 4pm in Arkles Bay and were still being heard at around 5pm in the Hibiscus Coast area. Inspector Tony Edwards of police northern communications said reports had been received from Herald Island, describing loud bangs like gun shots or some form of detonation, along with shaking that rocked houses in the affected locations.
Tectonic activity was ruled out by Geonet; utility companies could not find any form of electrical disturbance and the air force denied that aircraft were involved.

Experts even looked to the heavens to provide the answer: Astronomer Alan Gilmore, at Tekapo's Mt John Observatory, theorized that the booms could be meteors creating sonic booms, as several loud bollide incidents had previously occurred in New Zealand, but he had to discount the theory when multiple booms were reported. It was very unlikely that several meteors would strike in succession across such a small area, he said, adding "I think you'll have to look for a terrestrial explanation."

This is not the first time that New Zealand has experienced the boom phenomena. Back in 2006, Unknown Country reported booms across the country that seemed to be associated with sightings of a large, mystery cat,  an odd occurrence in a country that has no indigenous panthers, lions, tigers, leopards or wolves.

Elsewhere, the booms returned to Kentucky and Illinois earlier this year, when residents reported hearing the noises for two days in a row. The inexplicable sounds were accompanied by the now typical strong vibrations, leaving police and a number of public safety investigators baffled. The usual meteor strikes, seismic activity and sonic booms have again been ruled out as explanations, along with quarrying explosions or fracking activity.

Jason Lindsey from "Hooked On Science" has researched the booms with geologists, and suggested a couple of other theories that could explain the vibrations.

"Up in the Northwest, they had reports of these booms going on a few years back, and it turned out to be shallow earthquakes happening close to the surface. Instead of doing the damage and the rocking and rolling that you sometimes experience with an earthquake, you get more of a boom with maybe the windows shaking."

Lindsay's second theory revolves around the concept of "frost quakes":

"A frost quake happens whenever the temperatures drastically drop within a short period of time and there's water in the soil," Lindsey said. "That sudden drop causes the water to freeze and expand, cracking the rocks underground. Sometimes that can create what people hear as booms."

These ideas are still conjecture, however, and do not explain the vast number of other similar noises and judders that have been heard and felt around the world. The widespread yet consistent nature of the sounds adds to the mystery though, in other incidents, the noises have been described as "trumpeting".

Until a definitive answer is found, the booms continue to intrigue affected populations, and the rest of us. Do you have any ideas what could be causing these unnerving events? Subscribers can share their views with us - join our unique online community today!

Here's a syncronicity for you, Not an hour ago I was once again recording the "Pleasant Valley Booms" I recorded them last year on 7/19/13 and strangely, didn’t hear them again until a couple months ago. Then recorded them on 6/2/14 and heard them yesterday while I was in Placerville and couldn’t record them, then tried to record them again today without success. Not sure why they did’t show up on the recording today, but the sound of the booms have changed. Today I heard a triple boom instead of the usual double boom. The last boom was a very strange multiple random boom like I’ve never heard before.

Is there any way to fix this so we don't save the same comment more then once? ...or, better yet, allow the original poster to delete a multiple post?

A couple of months ago, on a Sunday evening here in Central Texas, my friend and I were watching TV when we heard what we thought was a 'boom box' approaching down a near-by street. I commented at the time at how annoying, and inconsiderate, that can be. Mere moments later that throbbing, pulsing, beat was directly over my house! The whole house shook for a few moments and could be felt in the body too. My friend looked at me and said, "That is no boom box!" We ran outside to see what was going on and found---nothing. The sound had suddenly stopped. There was nothing going on outside, no cars, and strangely, no other people like us looking around outside for the source of the vibrating boom. In hindsight, it was pretty creepy, but not the strangest thing that I have experienced after living here for over 25 years. I haven't figured out yet if this place is a 'hot-spot', or if it is a hot-spot because I happen to live here. :-)
