New Zealand sinkhole reveals glimpse into 60,000-year-old volcano

WELLINGTON: A new sinkhole on a North Island farm as deep as four double-decker buses and almost the length of two football fields has grabbed the attention of New Zealand volcanologists.
The chasm appeared after heavy rainfall near the town of Rotorua and left a jagged scar on the landscape, exposing rock deposits from 60,000 years ago.
Experts believe rain dissolved underground limestone over thousands of years, eventually causing the ground to collapse and create the canyon.
“This is pretty spectacular, it’s a lot bigger than the ones I’d normally see,” volcanologist Brad Scott said of the chasm measuring 20 meters (66 foot) deep and 200 meters (660 feet) long.
Scott said the dairy farm where the fissure appeared lay on the crater of a long-dormant volcano.

“What I see in the bottom of the hole is the original 60,000-year-old volcanic deposit that came out of this crater,” he told TVNZ.
Farmer Colin Tremain said the sinkhole appeared overnight last week and was spotted by one of his workers during an early morning round to attend the cows.
While such holes were common on the property, this was by far the largest he said, admitting there was little he could do to stop his land disappearing in such dramatic fashion.
“(I’ll) put a fence around it and forget about it, waste of time filling it in,” he told Radio NZ.


‘Jetman’ stuns with Iron Man-style flight over Dubai

‘Jetman’ stuns with Iron Man-style flight over Dubai

  • The Frenchman hovered above Dubai’s coast before shooting off into the air and skimming the city’s skyline
  • Daredevil Vince Reffet’s carbon fiber wings are powered by four mini jet engines

DUBAI: Daredevil Vince Reffet has soared into the skies above Dubai in the latest “Jetman” stunt, taking off from the ground and climbing to 1,800 meters in a feat reminiscent of Marvel’s “Iron Man” and hailed as a world first.
Reffet and his collaborators, known as “Jetmen,” have literally scaled new heights with the help of jetpacks and carbon-fire wings, staging a series of aerial displays that send them tearing through the skies at breakneck speed.
In an awe-inspiring flight captured on viral video, the Frenchman on Friday hovered five meters above the crystal waters of Dubai’s coast before shooting off into the air and skimming the city’s skyline.


“We accomplished another world first in 100 percent autonomous human flight with @jetmandubai, who took off from the ground before soaring to a high-altitude flight of up to 1,800m!” tweeted Expo 2020 Dubai, the mammoth trade fair that will open in October.
The Jetmen had previously launched themselves into the air by jumping down from high platforms.
“It’s the result of extremely thorough teamwork, where each small step generated huge results. Everything was planned to the split second, and I was overjoyed by the progress that was achieved,” Reffet said in a statement.
“One of the next objectives is to land back on the ground after a flight at altitude, without needing to open a parachute. It’s being worked on.”

Reffet’s carbon fiber wings are powered by four mini jet engines. The equipment, which is controlled by the pilot’s movements, is capable of reaching speeds of 400 kilometers per hour.
On Friday, Reffet hovered five meters above the crystal waters of Dubai’s coast before shooting off into the air and skimming the city’s skyline.
The Jetmen have pulled off a series of eye-popping flights in Dubai, soaring in tandem above the world’s tallest building Burj Khalifa, and alongside an Emirates Airbus A380, the world’s largest commercial airplane.
Last year, Reffet and fellow Frenchman Fred Fugen also flew through the famed “Heaven’s Gate” archway in the mountains of China’s Hunan province.
