Supervolcanoes are among the most sinister natural creations Earth has to offer.

They go one step further than their regular volcanic neighbours in the intensity with which they explode, coming in at a magnitude of eight on the Volcano Explosivity Index (VEI).

It means that at some point in history, more than 1,000 cubic kilometres (240 cubic miles) of material blew out of their lids.

Perhaps the world’s best-known supervolcano is Yellowstone caldera, a vast crevice in Wyoming, US, that sits beneath a sprawling national park.

While millions of people visit Yellowstone every year, one volcanologist told Express.co.uk about the level of destruction that would take place in the event of an eruption — and the extent to which it would affect the world.

The way supervolcanoes might erupt depends on where they are in the world and what their geological makeup looks like.

Events range from avalanches of hot rock and gasses to extreme changes in the global climate.

This latter point would result from an eruption at Yellowstone, one that Professor Christopher Kilburn, a volcanologist at University College London (UCL), said would affect much if not all of the world.

“The immediate vicinity of the super eruption would be completely devastated,” he said.

But then comes the global effect: “That’s a different story. Clouds of fine volcanic ash will rise into the stratosphere and will block sunlight for maybe several years.

“More important is the release of volcanic gasses like sulphur dioxide, which form opaque droplets of sulphuric acid and reduce the amount of sunlight but for much longer than the ash.

“It would cause a total disruption of the global food supply; depending on where the eruption occurs it will have major knock-on effects.”

What scientists call a nuclear winter would ensue, where ash and debris from the eruption travel across the world and blanket the sky, blocking out a high percentage of sunlight.

This would reduce global temperatures and lead to crop failures, health implications, and reduced energy production.

Prof Kilburn continued: “If it happens at Yellowstone that would have the possibility to overwhelm the global economy because the world’s leading economy will be brought to its knees.

“Many economic repercussions would follow which would then disrupt trade, food supplies, general activities around the world and that in turn may lead to other destabilising effects.”

While such an eruption wouldn’t necessarily lead to the extinction of the human race, Prof Kilburn said many volcanoes and supervolcanoes aren’t actively being monitored to detect such movements.

“It’s a myth that the world is properly observing monitors,” he said.

Women’s rights groups and officials in Israel who have been working tirelessly for the past six weeks to document cases of rape and gender-based atrocities carried out by Hamas terrorists during their mass, brutal terror attack in Israel on Oct. 7., say the United Nations is ignoring them. 

They say they have also shared much of this evidence, some of it horrifyingly graphic and all of it extremely intimate, with the United Nations and groups that protect and empower women. 

The response: Silence. 

“We’ve sent letters and shared graphic documentation,” Sarah Weiss Maudi, a senior diplomat and legal adviser in Israel’s Ministry of Foreign Affairs, told Fox News Digital. “Their silence is so deafening that it’s sickening,” she said.

Weiss Maudi, who last year became the first Israeli representative to serve as a senior adviser to the president of the 77th Session of the U.N. General Assembly in New York, said that U.N. bodies, particularly U.N. Women, whose specific mandate is to champion the rights of women regardless of race or ethnicity, have simply refused to acknowledge that atrocities were committed against Israeli women – and young girls – despite much of it filmed by Hamas, and other Palestinian terrorists from Gaza, themselves.

More than 1,200 people were killed in the mass terror attack, which took place in more than 20 Israeli communities, army bases, and a mass music festival. A further 240 individuals, including women and young children, were kidnapped back to Gaza. While no victims of sexual crimes have yet to come forward directly – mainly because they were murdered, kidnapped, or are still reeling from the trauma, the Israel Police said last week that it had collected some 60,000 videos, including footage from the terrorists, victims, first responders, and CCTV, showing these gruesome crimes. Some disturbing eyewitness testimonies of gang rapes and other sexual acts have also been documented, the police said.

“What I don’t understand is that we provided very graphic and descriptive evidence of rapes, including gang rapes and the remains of semen on young girls, it was not good enough for the U.N.,” said Weiss Maudi. “Yet data provided by the Hamas Ministry of Health is accepted and quoted without any verification at all,” she added.

On the U.N. Women’s website, the only reference to Israel since the Oct. 7 massacre deals with the “devastating impact of the crisis in Gaza on women and girls,” where Hamas’ Ministry of Health estimates that more than 11,200 people have been killed, of whom some 4,506 are said to be children and 3,027 women.

U.N. Women also details a two-day trip to Egypt by its executive director, Sima Bahous, where she called for “immediate and unhindered humanitarian access,” to Gaza.
