The catastrophic undersea volcano that hit Tonga over the weekend erupted more than 10,000 miles (16,093.44 kilometers) away in Market Harbourough, which was incredibly captured by amateur radio amateurs.

After completely overpowering Tonga, home to 176 islands in the South Pacific, this powerful and destructive explosion has made headlines around the world.
On Saturday (January 15), 14 hours into the evening, a highly sensitive sensor in Market Harborough detected a violent shock wave, which also caused a sensation closer to home.
Peter Rivers, 67, secretary of the Welland Valley Amateur Radio Association, was stunned and told Harbourough Mail: "It's absolutely unbelievable.
"It could be a once-in-a-decade event — if that's the case.
"Pressure waves from the tonga eruption swept past Market Harborough and suddenly peaked sharply.
"It sped up towards us around 7:10 p.m. on Saturday," said Peter, a retired geologist.
"That was about 14 and a half hours after the eruption."
"The shock wave traveled about 10,200 miles at just over 700 mph."
"I just think wow!"
"The pressure chart is out of the ordinary."
"It's incredibly dramatic, it's hard for you to understand," said the father of two, who is already a child of two.
"I just find it fascinating to be able to sense and measure the actual sound of the Earth as a geologist."
"Amazingly, we were hit by this amazing wave of pressure from a massive volcanic eruption on the other side of the world.
Other radio amateurs in the UK and Europe have also reported on it.
"You can imagine the radio frequencies and chat groups buzzing."
Peter said that just before the first lockdown in March 2020, about a dozen like-minded people formed the booming Welland Valley Amateur Radio Association.
"We suddenly had a lot of time and decided to do something with it.
"Highly motivated enthusiasts throughout the Hubbleugh area get together," he said.
"We set up a network of sensors in welland Valley to measure all kinds of meteorological and other data and send it into the network.
Peter said: "The chips and sensors we use are cheap goods that are bought from the internet, and we just experiment as an experiment and have fun with it. ”
"The group got along very well.
"And the Tonga eruption is clearly the most unusual thing that has happened to us so far."
