More than 500 tremors have rocked the Wyoming-based volcano in a matter of days, leading to renewed fears the volcano could erupt.
The strongest of the quakes was a 4.4 tremor which hit on Thursday, June 15.
The Yellowstone Caldera supervolcano last erupted 70,000 years ago but a spike in seismic activity around the national park has unsettled nerves.
If the Wyoming volcano were to erupt it would kill an estimated 87,000 people immediately and make two-thirds of the USA immediately uninhabitable. The as the large spew of ash into the atmosphere would block out sunlight and directly affect life beneath it creating a “nuclear winter” and threatening ALL life on earth.
The volcano is 80 km (50 mi) long 20 km (12 mi) wide and the 1500F chamber of molten rock beneath the surface is seven miles deep.
The caldera is so huge volcano-hunting scientists failed to spot it for years unaware they were walking all over it.
The massive eruption could be a staggering 6,000 times as powerful as the one from Washington’s Mount St Helens in 1980 which killed 57 people and deposited ash in 11 different states and five Canadian provinces.
Additionally, a climate shift would ensue as the volcano would spew massive amounts of sulphur dioxide into the atmosphere, which can form a sulphur aerosol that reflects and absorbs sunlight.
Researchers from the University of Utah’s Seismograph Stations (UUSS) have been monitoring the activity since it began last Monday, last week.
The strongest quake of 4.4 magnitude hit on Thursday, June 15 and the latest on Monday, June 19, saw magnitude three earthquake striking 8.6 miles (14 km) north northeast of West Yellowstone, Montana.
UUSS described the swarm as “an energetic sequence” of earthquakes in the area.
A spokesman said: “The epicentre of the shock was located in Yellowstone National Park, eight miles north-northeast of the town of West Yellowstone.
“The earthquake was felt in the towns of West Yellowstone and Gardiner, Montana, in…
