Earth's magnetic field may be headed for a cataclysm says latest French study

We've reported on Earth's magnetic field before, including studies claiming that the planet's poles may reverse at any time and studies saying that Earth is probably not headed for a polar reversal at all. At the heart of these studies is the undeniable, millennia-old weakening trend in the planet's magnetic field, which, depending on your point of view, is either a temporary phenomenon that will eventually reverse itself (as it has in the past), or the harbinger of a cataclysmic breakdown of the Earth's entire magnetic shield and a subsequent flip of the magnetic poles.

The most recent study from the EDIFICE project, a geophysical research initiative based in France, claims we're headed for a cataclysm. According to Dr. Nicolas Thouveny, one of the principal investigators for EDIFICE: "The geomagnetic field has been decaying for the last 3,000 years. If it continues to fall down at this rate, in less than one millennium we will be in a critical (period)."

Loud mysterious booms rattle homes and nerves in northeastern Illinois

Mysterious boom sounds in the middle of night have residents in Elgin tired and looking for answers.

Some residents say the booms are so loud, they even shake homes in the northwest suburb.

"The house shakes, the windows shake," said resident Colleen Roberg.

The noises have been heard at various hours of the day, but particularly overnight.

"They've become louder," said Sue Webb, president of the Southwest Area Neighbors group.

The SWAN group said residents have suspected two bridges as the possible cause of the booms - the Route 31 bridge that runs over Route 20 and the Route 20 bridge the crosses over the Fox River.

'Cannons': Strange booming sounds heard in Southeastern, Pennsylvania

YouTuber 'Christine Diamond' uploaded video of 'crazy sounds' she heard in the skies of Delaware County, Pennsylvania on December 2, 2018.

'Christine' notes:
People around here keep insisting it was a firework show in the next town. However the sound was very loud and deep it did not sound like a firework show.
Two commenters on the video reported they heard the same sounds. One was in New Jersey and the other in Verona, Pittsburgh who said they heard the noise twice in the last two weeks.


Comment: The above video has since been removed by the user. The same clip was posted on YouTube by 'Mystic Hippie' on December 29th::
This video was taken on 12.02.2018 @ 18:15. We were sitting in the house when we could hear it for a good 30 minutes. Finally we decided to go outside and record it. The video doesn't do justice to what it sounded like. It was a deep sound as if there was bombing going on at a distance. We did rule out fireworks by phone calls we made to surrounding towns.

I actually had this on my personal channel and had no idea of the popularity it quickly gained. I'd rather this be on my public channel so I've moved it here.

A loud boom sound and shake was heard in Salisbury and the surrounding areas on Thursday afternoon.

On Oct. 25 around 3:30 p.m., a sound caused a stir with a audible boom and shake.

Residents quickly turned to social media to find out if others had heard the boom. Facebook posts were reported from Salisbury, Seaford, Delmar, Dagsboro, Ocean Pines, Hurlock, Princess Anne, Bishopville, Snow Hill, Vienna and Fruitland.

Patrick Gordon, NAS Patuxent River public affairs officer, said while they do have aircraft flying in the area, none were approved to go supersonic, so they were not the cause.

Keith Koehler, NASA Wallops spokesperson, said he heard nothing in Virginia.

Eerie 'singing' sounds heard coming from the Antarctic ice shelf

Scientists have heard strange "singing" noises coming out of the ice shelf.

The low-frequency noises - which sound a little like moaning when sped up - could help researchers track the ice shelves as they collapse.

The singing tones come out of the surface of the massive Ross Ice Shelf when the winds blowing across the snow dunes cause it to vibrate. That means they produce the "tones" almost constantly, and now scientists have found they can listen to them.

Doing so could help them spot how the ice shelf is forming from afar, and track the damage that is being done by climate change by tuning into the tones.

Ice shelf collapses can be drastic and sudden. When they do, they can change the flow of water and raise sea levels, making it important to watch for any signs as they occur.

To try and understand how the Ross Ice Shelf is arranged, scientists put 34 very sensitive seismic detectors under its surface. They then monitored its vibrations from late 2014 to early 2017.

When they checked in on that data, they found that the snowy coat that sits on top of the ice shelf appeared to be almost constantly vibrating.

It was then they found that the shaking was caused by the winds travelling across the huge snow dunes and making the snow rumble, like a huge drum.
