Humans have always been attracted to nature. Being the curious species that we are, we tend to love to wander in the great outdoors and enjoy the beauty of nature (even if we’re just viewing pictures taken on the hikes of others). Many people love to be out and about, exploring different parts of the world. These adventurers often end up in strange, unusual, and even precarious situations, but that’s the price you pay for the freedom to roam and appreciate the dazzling sights the world has to offer.

Sometimes, when hiking on volcanoes, people somehow end up inside. In the case of active volcanoes, the terrifying, molten lava is enough to scare most people away from the site for good. Falling into an inactive or dormant volcano is no joke, either, as volcanic craters can be thousands of feet deep. Here are ten such people who either fell or jumped—yes, jumped—into a volcano.

10 The Family

Solfatara is a sulfurous volcanic crater near Pozzuoli, Italy, and is often a tourist destination for people who want to catch a glimpse of a beautiful sight. While the volcano is dormant and hasn’t erupted since 1198, it’s still quite hot, with magma beneath its surface and boiling sulfur inside of it.

In September 2017, a family of four, a couple and their two sons, went to see the attraction.^[1] Then, the older brother, age 11, slipped and and fell into a hole that cracked beneath his feet. The parents, frantic, tried to save their son, but they, too, fell into the hole after tragically being overcome by the sulfuric fumes and losing consciousness. The younger brother, seven years old, managed to escape to safety and survive the traumatic experience.

9 Cecilia Cheng Siu-Yan

The Nyiragongo volcano is located in Africa’s Virunga National Park, which lies in the Democratic Republic of the Congo. In 2007, a 33-year-old woman from Hong Kong named Cecilia Cheng Siu-yan had climbed atop the towering volcano, which stands nearly 3,500 meters (11,500 ft) above sea level, when she accidentally got stuck on a ledge inside the volcano’s crater.^[2] She finally fell into the massive, active volcano, which hasn’t erupted since 2002 and is known for containing a lava lake.

Rescue teams searched for the woman but weren’t able to determine if she had fallen onto the rocks which lie within or actually into the massive pool of lava itself. A helicopter was deployed, and a team made up of members of the Indian army as well as others all came together to search for the missing woman. They eventually found her lying on a bed of rock, having fallen 200 meters (656 ft). She was dead, and the team believed she died from the fall.

8 Gregory Michael Ure

Leo Adonis, born Gregory Michael Ure, was a 38-year-old California man who met a similar, tragic fate—he died inside a volcano in 2017. The man loved Hawaii and climbed to the top of a volcano there before apparently falling inside. But he left behind his backpack, which was later found by hikers on the Crater Rim Trail after he had fallen.^[3]

Inside the backpack, the hikers discovered something startling: a suicide note. Leo Adonis had chosen to die by jumping into the volcano. Investigations were conducted and concluded that the man did, in fact, commit suicide-by-volcano. He jumped to his death and landed on the outer rim of the volcano crater, rather than the lava itself.

7 Kiyoko Matsumoto

Mount Mihara is a volcano on a small island in Japan called Izu Oshima, and it has an extremely unusual backstory: The volcano was used extensively for suicide in the early part of the 20th century, much like Japan’s suicide forest, both of which have been places where thousands of people have taken their own lives. Throughout much of the 1920s and 1930s, suicide fever seemed to catch on, with someone jumping into the volcano almost every single day during those two decades.

One young woman in particular named Kiyoko Matsumoto did just that on February 12, 1933. The poor girl had fallen in love with another girl from her school named Masako Tomita. Same-sex relationships were extremely frowned-upon in Japanese society at the time, and Kiyoko decided that she simply couldn’t live without the love of her life.

In a strange turn of events, since they couldn’t have one another, the two marched up the mountain together, and Kiyoko jumped into the volcano so that she would be burned alive in the lava.^[4]

6 Maasai Porter

One instance of falling into a volcano happened to a poor man who was part of a group exploring Ol Doinyo Lengai, a bizarre and active volcano in Tanzania. The name “Ol Doinyo Lengai” means “Mountain of God” in the local language, Maasai.

Not all falling-into-a-volcano stories end the same; as we’ve seen, these incidents happen for vastly different reasons, and they also have extremely different outcomes. The unnamed man fell into the volcano—but amazingly, he survived!^[5] The date was August 21, 2007. A team was walking on the volcano, and a Maasai porter fell into a lava-filled crevice. His arms and legs were severely burned, but amazingly, the porter climbed out of the lava himself.

How did this man get so lucky and survive falling into lava? It has to do with Ol Doinyo Lengai’s unusual lava, which never goes above 510 degrees Celsius (950 °F), making it an extraordinarily cool volcano, though still hot by our standards, obviously. Such lava is usually a slow-moving, black, rolling, viscous liquid, rather than the bright red or orange, bursting, streaming, and flowing liquid we usually see. The man placed his pack down and stood on it until he was able to climb out of the thick, slow sludge and make it to safety.

5 John Slemp

Mount St. Helens has been one of the most famous volcanoes in the United States, if not the world, since its eruption in 1980. In 2008, a 52-year-old man from the neighboring state of Oregon named John Slemp was snowmobiling near the volcano. His son had just returned from the war in Iraq, and the two decided to take a friend out to the volcano to cruise around on snowmobiles for a bit of fun. Then they decided to hike to the rim of the crater, but when they reached the top and walked over to the rim, a day of fun and games quickly fell apart, turning into a nightmare scenario—John Slemp fell into the volcano.

Slemp fell a total of 457 meters (1,500 ft) yet would miraculously survive. His descent was stopped by a snowbank after about 46 meters (150 ft), but then it crumbled, and he slid the rest of the way.^[6] Help was called, and Slemp had to be rescued by a team with a helicopter. Medical technicians arrived on the scene within hours and were able to save the man’s life.

4 George Kourounis

Canadian storm-chaser, adventurer, and explorer George Kourounis is an interesting character who’s been the star of several TV shows in which he thrusts himself into some pretty mind-blowing, crazy situations in the natural world. He and his wife even got married on the top of an active volcano—while it was erupting.

The things George has done are already crazy enough, but then he got the bright idea to descend 366 meters (1,200 ft) down inside a live, active, lava-filled volcano with a rope attached and two cameras. He had a Canon professional-grade camera and a GoPro and descended into the volcano, getting as close to the underbelly of this thing as he could.^[7] He got so close that the heat from the lava ended up melting through a portion of his suit and part of one of the cameras. The stunt was all recorded and watched by his team, and Kourounis survived the expedition.

3 Bali Tourist

In March 2010, yet another man fell into a volcano, this time in Indonesia’s Mount Batur in Bali. The unnamed Swedish tourist was taking a hike up to the rim just before dawn, to catch the sunrise from the top of the active volcano, when suddenly, he fell in accidentally.^[8] This poor backpacker was just going up to the top of the mountain to catch a beautiful sight and ended up being swallowed in the belly of a volcano.

The man fell about 150 meters (500 ft) and died instantly. Three friends had gone with him that morning, so it wasn’t a suicide, just a peaceful predawn hike to the mountaintop that went very, very wrong. The path the Swedish tourist was walking is actually considered extremely safe by the authorities who monitor the volcano, so this was just a tragic, freak accident.

2 Unnamed Woman

It was an enjoyable day on vacation in Bali for British firefighter John Conway. Eight years after the Swedish tourist had fallen to his death, Conway was enjoying his own hike on Mount Batur, when suddenly, a woman who was also hiking the volcano fell off a platform and into the crater. Fortunately, she only ended up falling 40 meters (131 ft) when she took the plunge accidentally, and John’s firefighter instincts sprung quickly into action.

He gathered some people nearby and came up with the genius idea of forming a human chain, arm-in-arm, to get down there and rescue the woman. The attempt was successful. John returned the unnamed woman to safety and used his firefighter training to keep her conscious and alive until help could come.^[9]

1 Mount Mihara

No list about people falling or jumping into volcanoes is complete without considering the thousands of lives that ended by suicide at Mount Mihara, which we’ve only briefly touched upon above. This active volcano has been used extensively for suicide over the years and has seen thousands upon thousands of people jump into it. It was even featured in one of the Godzilla movies as a place that Godzilla was imprisoned until the following sequel.

There’s a certain point on the volcano which is a perfect spot for people to jump into the crater, aptly called “Suicide Point.” In decades past, Suicide Point drew hundreds of people per year, all of whom wished to end their lives in one of the most bizarre and almost unfathomable ways possible—by jumping into a volcano.

In 1933 alone, 944 people committed suicide by jumping into Mount Mihara. The following years were still particularly haunting, as at least 350 more people jumped into the volcano between 1934 and 1935.^[10] Eventually, to curb the mass of suicides that took place at this particular site, the Japanese authorities built fences and barriers to stop people from being able to so easily jump off Suicide Point and even made it outright illegal to purchase a one-way ticket to the island of Izu Oshima, on which the volcano is located.

Japan has a long, rich history with volcanoes, with one of them serving as an execution chamber in past centuries. Mount Unzen was used for the execution of criminals and Christian trespassers from the 17th to the 19th centuries, making Mount Unzen to execution what Mount Mihara is to suicide.

I like to write about the strange and unusual, dark stuff, true crime, and history.

Expert answers often come with jargon that can put you to sleep.

News stories help, but misinformation tends to creep in now and then. Journalists can’t be expected to sort through scientific minutiae during a crisis.

It’s up to us to figure out the truth. And as you read through this list, you might be surprised at what you only think you know!

Everyone loves watching volcanoes from a safe distance and sometimes even when they threaten us. That fiery power is fascinating.

We’re curious, too. How do eruptions happen? Is it safe to climb a volcano? What are supervolcanoes?

10 Utterly Spectacular Volcanoes In Space

10 Misconception: Molten rock powers eruptions

About 25-30 kilometers (15-20 miles) below our feet, there is intense heat and pressure. Some kinds of rock melt under these conditions, forming magma.^[1]

That red-hot liquid rock has enough buoyancy to rise towards the surface through cracks in the overlying crust. It might not get there but if it does, there will be an eruption.

There’s a long way to go, though. Surely the weight of the overlying rock helps squeeze the magma along?

Nope. It’s running on gas — not fossil fuel, the gases dissolved in the molten rock. These include water vapor, carbon dioxide, and sulfur dioxide.

Gases bubble out of the magma as it gets higher, since the pressure is decreasing because there is less rock. You can safely get the same effect by opening a carbonated beverage bottle; the contents are under pressure, but carbon dioxide bubble appear when the seal is released.

But our magma conduit is still capped, so the gases have nowhere to go but out into the conduit. This speeds up the rising melt, and a chain reaction starts that can lead to an eruption, if the gases don’t run out and the magma doesn’t encounter a barrier of some sort that it can’t pass.^[2]

If it does stop, then the magma will begin to cool, eventually freezing in place as a dike, sill, or pluton. Erosion sometimes uncovers these structures, revealing their beauty in places like Devil’s Tower in Wyoming.^[3]

9 Misconception: Lava always erupts in flows

What’s missing here is the other half of the picture: lava can also explode onto the scene. We’re too busy running away or watching it in awe from a safe distance to realize that this is lava, too.

It all depends on the gases mentioned earlier, as well as the rising magma’s temperature and viscosity.

Temperature is a no-brainer. Molten rock reacts much like molasses does to temperature changes, slowing down as it cools off.

Viscosity isn’t complicated, either. Water has very low viscosity; asphalt is quite viscous.

Gases bubble away in water; asphalt won’t let them pass. This matters because rising magma is driven by gases.

It also contain silica, which tends to form long chains of molecules, increasing viscosity.^[4]

The end result of all this geochemistry?

Low-silica magma lets most gas bubble away before the eruption, keeping just enough to power either a gorgeous Hawaiian-style lava flow, or if there’s a fair amount of silica present, something like the clip above.^[5]

High-viscosity, high-silica magma, on the other hand, hangs onto more of its gases, building up more internal pressure. A similar pressure increase happens when you shake a champagne bottle.

Either way, the bubbles have nowhere to go until you uncork that bottle or the volcano’s rock gives way. Then, BOOM!^[6]

You now have a champagne-splattered sports team and a countryside covered in shattered lava, respectively.

8 Misconception: Volcanoes erupt smoke

Actually, the solid material in that impressive plume is rock and natural glass.

Don’t believe it? Ask Mexico’s Popocatepetl Volcano.^[7]

During the terrible wildfire season this year in both hemispheres, we have seen plumes above major fires that certainly looked volcanic. But there is a big difference in their contents.^[8]

Volcanic ash isn’t fluffy like bushfire ash. It’s all tiny bits of jagged stone and natural glass that get into your lungs and behind your contact lenses.

It’s heavy, too.

According to the US Geological Survey just 4 inches of it weighs 120-200 pounds per square yard. Even small accumulations of volcanic ash can overload and collapse a roof.

It will also do a number on your home electronics and cause power outages, since volcanic ash conducts electricity.^[9][10]

Volcanic ash damages cars and other machinery. You will never see smoke affecting jet engines like this!

This is why there are Volcanic Ash Advisory Centers (VAAC) around the world,^[11] constantly on the lookout for ash clouds in global flight lanes.

7 Misconception: Lava and pyroclastic flows are the deadliest hazard at volcanoes

Pyroclastic flows are indeed lethal. Lava flows, not so much.

Lava usually moves slowly enough that you can get out of its way.^[12] There are exceptions, so don’t get cocky next time you visit an active volcano. Nevertheless, a study that looked at volcanic fatalities between 1500 AD and 2017 found that fewer than 700 people had been killed by lava.

Pyroclastic flows, which travel farther and much faster than lava, have a body count of almost 60,000 people. What could possibly match that?

Would you believe mud?^[13]

What happens is that water mixes with volcanic ash, forming a heavy mixture like wet concrete that races down river drainages faster than people can run.

Volcanologists call these mudflows by their Indonesian name: lahar. You don’t want to get caught in one.

Lahars can also happen without an eruption. All that’s needed is water and loose ash. Heavy rainfall and tropical systems are notorious for causing secondary lahars.

In 2007 video above, the water came from a crater lake at New Zealand’s Mount Ruapehu:

All told, volcanic mudflows of various types have murdered almost 60,000 people over the last five centuries. They’re as hazardous as pyroclastic flows!

6 Misconception: Lakes don’t erupt

We all know that volcanic eruptions at sea are awesome.^[14] Volcanoes near water can also cause tsunamis, like the one at Anak Krakatau in Indonesia in 2018 that killed four hundred people.^[15]

Most of us, though, would never expect water to take the initiative and erupt on its own. But lake eruptions do happen, although there is usually a volcano lurking somewhere in the background.

That volcano’s gases seep through the lake bed into the water. Under the right circumstances (described below), they build up to the point where the lake explodes, unleashing all that gas in one deadly event.^[16]

Lake Kivu, which is described in the video above, sits at the feet of Mount Nyiragongo in the Democratic Republic of the Congo.

Researchers are worried that future volcanic eruptions could start right under the city of Goma, located on the shores of Lake Kivu. That would be bad enough, but it likely would also set off a lake eruption, leading to a double tragedy.

But why would lava erupt in town, 14 kilometers (9 miles) from the volcano?^[17]

Top 10 Amazing Volcano Lakes

5 Misconception: Eruptions start at the top of a volcano

Tell it to Mount St. Helens, which first exploded sideways in 1980 after a landslide removed rocks overlying the magma inside the mountain!

Active volcanoes do usually have at least one summit crater, but molten rock will exploit any zone of weakness it meets.

In 1977, for example, and again in 2002, Mount Nyiragongo’s famous lava lake drained out through large cracks in the surrounding rocky walls. The unexpected flank eruptions happened far down the volcano’s slopes, where there were villages, and many people died.

Volcanic fissures usually come in a network and can be quite extensive. One such system extends from Nyiragongo’s summit all the way to Goma, the provincial capital that sits on the shores of potentially deadly Lake Kivu.^[18]

While no activity has been seen there in recorded history, it’s entirely possible that those fissures could host a future eruption.^[19] And as we’ve seen, that could be a double catastrophe if it causes the lake to erupt, too.

On a happier note, beautiful Iceland is riddled with fissures – it sits on an area where two tectonic plates are slowly moving apart.^[20]

Many fissure eruptions occur here. The last one, in 2014 at Bardarbunga Volcano, didn’t disrupt North Atlantic air traffic very much. It was also a spectacle.

In this video of drone footage, it sometimes looks as though the lava is coming from a crater. That’s actually a spatter rampart, where cooled globs from the lava fountains collect.^[21]

4 Misconception: Exclusion zones are suggestions, not rules

Scientists go up there, why not us?

Because what you don’t know about a volcano can get you killed. This applies to experts, too.

In 1993, for example, a team of international volcanologists entered the crater of Colombia’s Galeras Volcano, which had been quiet for five months, to collect data on it for the Decade Volcano program.

They knew the risks and were ready to run whenever other scientists, who were monitoring the volcano’s real-time “vital signs” from a nearby observatory, spotted the least sign of impending trouble.^[22]

Galeras gave no warning and exploded anyway, killing six volcanologists and three local residents who had come up to watch the fieldwork.^[23][24]

Sudden changes like this are bound to happen when you have a mountain-sized pressure cooker sitting on a hot burner — even in “safe” places.^[25][26]

Exclusion zones are common-sense rules, based on experience gained at the cost of human lives: almost seventy scientists and hundreds of thousands of other people.^[27]

Even the tragedy at White Island/Whakaari Volcano in December 2019 spurred advances in volcanology.^[28]

Sometimes a scientist takes chances, hoping to save many lives in the future.

But what about you? Are selfies, boasting rights, and the view worth entering a no-go zone and possibly ending up as just a data point on someone else’s research graph?

3 Misconception: All big eruptions are Plinian

For most of us, any explosive eruption is awesome. They’re Plinian, right, with the other type being pretty Hawaiian-style flows and fountains?

Actually, the Volcanic Explosivity Index (VEI) starts off with Hawaiian eruptions at VEI 0 and works its way up to VEI 8, a supereruption.

Along the way are a few intermediate grades and four different Plinian types.

Pictures are worth a thousand words, so let’s look at two explosive eruptions.

The clip above is Taal Volcano in January 2020, which certainly was a big and scary event.

It doesn’t yet have a VEI number, but Philippine volcanologists describe this eruption as steam related (“phreatomagmatic”).^[29]

In terms of intensity, that’s not even close to Plinian.

While that certainly meets Pliny the Younger’s description of the Pompeii-destroying Mount Vesuvius eruption in 79 AD,^[30] scientists can be fussy over details.

Some call this “classic Plinian”,^[31] while others describe it as subplinian.^[32]

The VEI scale gives geoscientists a common starting point for subtle disagreements like this. For example,^[33]

• VEI 4 is “Pelean/Plinian”; think Eyjafjallajokul, the Icelandic volcano that messed up air traffic in 2010.
• VEI 5 is “Plinian”; Mount St. Helens, 1980.
• VEI 6 is “Plinian/Ultraplinian”; Pinatubo, 1991.
• VEI 7 is “Ultraplinian”; Tambora’s huge nineteenth-century eruption.^[34]

Luckily, humanity hasn’t experienced a VEI 8 during recorded history. What would that be like?

2 Misconception: Supereruptions are like nuclear blasts

Which is easier: trying to absorb the fact that a supereruption blasts out at least 1,000 km3 (240 cu mi) of material^[35] or just letting film makers and game designers imagine it for us?

Of course we go with simulations. Since the scale of such real-life events is beyond our experience, special effects artists often go nuclear.

Sometimes they try to stay close to science. Unfortunately, very little is definitely known about supereruptions, other than that at least two other giant calderas in the US besides Yellowstone have erupted during the last two million years, along with others in New Zealand, Indonesia, Japan, and South America.

Of these, Taupo in New Zealand hosted the world’s most recent supereruption about 23,000 years ago, while Indonesia’s Toba supereruption 74,000 years ago was the largest.

Currently, scientific explanations for how supereruptions happen include:

1. “Unzipping”: Multiple Plinian eruptions happen along giant ring fractures in the ground, emptying out the magma chamber below, which in turn collapses to form a caldera. This may have happened at California’s Long Valley Caldera.^[36]

2. “Boiling over”: Some supervolcanoes, like Cerro Galan in Argentina, show no evidence of Plinian eruptions. Perhaps very dense clouds of crystalline magma poured out of the developing caldera here but were too heavy to rise very high (clip above).

We’ll never really know how supereruptions happen until we experience one. Let’s hope we survive it!

1 Misconception: Any supervolcano eruption means the end of the world

As little as we know about supereruptions, it’s still clear that the global consequences of one would be terrible.

But this doesn’t mean that we should all panic if the Yellowstone Volcano Observatory,^[37] or its equivalent at any other supervolcano, ever posts a warning.

Small eruptions happen, too. In fact, experts note that Yellowstone’s most likely next round will either be a hydrothermal blast (a steam explosion large enough to toss rocks around) or a lava flow.^[38]

Relatively small hydrothermal explosions are common at Yellowstone, happening every two or three years. Larger ones, those that form craters several hundred meters wide, occur every few thousand years.

And Yellowstone has had eighty known lava flows since its last VEI 8 some 630,000 years ago; the last one took place about 70,000 years ago. Such nonexplosive activity wouldn’t have much impact outside Yellowstone Park.^[39][40]

Could scientists monitoring Yellowstone tell whether an impending eruption was going to be small or supersized? Yes, probably.

Because of the huge volume of magma on the move, a supereruption is likely have enormous precursors — those changes in seismicity, ground deformation, chemistry, and other measurements that signal upcoming changes in any volcano’s behavior.^[41]

Even if a supereruption took place, it might not be an extinction-level event. Something too big to fit on the VEI scale, now, *that* would be a problem.

+ Misconception: Supervolcanoes are the biggest eruptions known

Don’t panic, but every twenty million years on average, the ground opens up and millions of cubic kilometers of molten rock either flow or explode across the land for 1-5 million years at a stretch.^[42]

The word “millions” is why you shouldn’t panic.

The last time it happened was around 15 million years ago in the Pacific Northwest. Geologists call this large igneous province (LIP) the Columbia River Basalts because its eerie rocks now form the beautiful walls of the Columbia River Gorge.^[43]

So we’ve got at least 5 million more years to go.

LIPs involve the sort of cutting-edge research that goes way beyond the scope of this article.

It’s fun to know, though, that geoscientists maintain a LIP of the Month web page.^[44] That’s actually a pretty cool feature, even if (like most of us) you don’t have a PhD.

And it’s fascinating to think that volcanologists have found connections between some of these ancient events and a few modern volcanoes – relating Yellowstone to the Columbia River Basalts LIP, for instance, and Australia’s rare volcanic beauties, Heard and McDonald islands, to the mostly submerged Kerguelen Plateau LIP.^[45][46]

Don’t worry. These places aren’t suddenly going to come to life again. They’re just the last flickering flames of a once terrifying fire upon the land.

Yellowstone still needs watching, but Heard Island is already wrapped in a thick blanket of snow and ice.

10 People Who Actually Fell Into A Volcano
