Hundreds of earthquakes have hit Yellowstone National Park in the space of a week, according to experts. A total of 464 quakes have been recorded over the past week at Yellowstone, which sits above one of the world’s most dangerous supervolcanoes.
This is the highest number of earthquakes at the park within a single week in the past five years. The recent activity has raised fears that the supervolcano is about to blow.
If it were to erupt, the Yellowstone supervolcano would be one thousand times as powerful as the 1980 Mount St Helens eruption, experts claim – although they say the risk is ‘low’…
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 Yellowstone National Park, and elsewhere in the surrounding region.’
Earthquake swarms are common in Yellowstone and, on average, comprise about 50 per cent of the total activity in the Yellowstone region.
Although the latest swarm is the largest since 2012, it is fewer than weekly counts during similar events in 2002, 2004, 2008 and 2010. DailyMail
Researchers Say – Nothing To Be Alarmed About
Researchers say it’s nothing to be alarmed about, though.
In a statement to the Star Valley Independent, scientists from the University of Utah — which monitors the volcano — said the earthquake swarms are nothing new.

In a written statement, a spokesman for the team said: ‘Yellowstone hasn’t erupted for 70,000 years, so it’s going to take some impressive earthquakes and ground uplift to get things started.’
‘Besides intense earthquake swarms, we expect rapid and notable uplift around the caldera. ‘Finally, rising magma will cause explosions from the boiling-temperature geothermal reservoirs.
In the heart of Yellowstone National Park, a supervolcano releases around 45,000 metric tonnes of carbon dioxide each day.
But the magma chamber lying directly beneath its surface is not considered large enough to produce such levels, so researchers have been searching for an alternative source for years.
In April 2015, by tracking seismic waves, geophysicists discovered a huge secondary chamber deeper underground that’s so large its partly-molten rock could fill the Grand Canyon 11 times over. DailyMail
