The 10 Most Dangerous Volcanoes on the Planet

Around the planet, there are a grand total of 1,357 active volcanoes. With so many volcanoes, it is quite difficult to decide which individual volcanoes are the world's most dangerous. This video takes into account every active volcano in existence, and uses the scientific method to determine what are the most dangerous volcanoes on the planet. Included in this list are volcanoes such as Vesuvius, Taal, Aso, and Nevado del Ruiz.
The methodology used is linked in this USGS paper:

This video is not opinion based, but rather relies on a tested scientific criteria to accurately determine which volcanoes on the planet are the most dangerous. Included below are the 25 most dangerous volcanoes, the scores they were assigned, and some other notable volcanoes which missed the cut. Important factors include: -how often the volcano erupts -how large its eruptions are -how many people are at risk from an eruption -volume of air traffic -slope failure potential -lahar danger, and other factors. I want to note that after #30, my list may be incomplete. Here is the list: 1-Taal: 390 (Philippines) 2-Krakatoa: 380 (Indonesia) 3-Vesuvius: 366 (Italy) 4-Sakurajima / Aira Caldera: 357 (Japan) 5-Campi Flegrei: 355 (Italy) 6-Aso: 354 (Japan) 7-Rinjani: 354 (Indonesia) 8-Mount Etna: 332 (Italy) 9-Fuji: 330 (Japan) 10-Tarawera / Okataina: 329 (New Zealand) 11-Galunggung: 315 (Indonesia) 12-Kikai: 315 (Japan) 13-Agung: 315 (Indonesia) 14-Kelud: 308 (Indonesia) 15-Mount Teide: 308 (Spain, Canary Islands) 16-Merapi: 306 (Indonesia) 17-Ata: 306 (Japan) 18-Tambora: 305 (Indonesia) 19-Popocatépetl: 300 (Mexico) 20-Santorini: 303 (Greece) 21-Nelvado Del Ruiz: 301 (Colombia) 22-Ilopango: 296 (El Salvador) 23-Cotopaxi: 293 (Ecuador) 24-Galeras: 292 (Colombia) 25-Pelee: 292 (Martinique) 26-Furnas: 292 27-Mayon: 291 28-Avachinsky: 290 29-Mount Pinatubo: 290 30-La Soufriere: 283 31-Unzen: 282 (decade volcano) 32-Arenal: 274 33-Fuego: 271 34-Taupo: 270 (Supervolcano) 35-El Chichon: 268 -Mount Baekdu: 265 -Colima: 264 -Stromboli: 264 -Kilauea: 263 -Ambrym: 257 -Santa Maria: 255 -Mount Saint Helens: 235 -Katla: 232 -Hekla: 228 -Nyiragongo: 225 -Huaynaputina: 205 -Mount Rainier: 203 (decade volcano) -Grímsvötn: 201 -Nabro: 194 -Eyjafjallajökull: 183 -Toba: 180 (Supervolcano) -Atitlan: 178 (Supervolcano) -Mauna Loa: 131 (decade volcano) -Crater Lake: 129 -Long Valley (Supervolcano): 129 -Yellowstone (Supervolcano): 115 -Valles Caldera (Supervolcano): 60

[@larkmacgregor3143]

I am shocked that Mt. Rainier is so far down on this list. It's a large stratovolcano with the danger of lahars, long distance pyroclastic flows, and a densely populated area in those flow paths. I guess that because it's been so long since it last went off, it's viewed as less dangerous. But the idea that it is somehow less dangerous than Kilauea, which is a shield volcano and not known for explosive eruptions, seems odd to me.

[@GeologyHub]

Mount Rainier is still quite dangerous, but several factors hold it back. For one, it hasn’t killed anyone (yet). It doesn’t erupt as frequently as other volcanoes on this list. Also, it’s eruptions are generally less than VEI 4

[@howitzersupercell240]

I'm having goosebumps while watching this video - specially knowing that Taal is less than 50kms away from my house. When it erupted last Jan 2020, one of the major problems is the evacuation from it's danger zone. If i recall correctly, Taal started steaming at around 11am and started it's eruption at around 1-2pm. At around 7pm, I saw the news where people are still having troubles escaping due to the heavy traffic. Good thing Taal's eruption that time is upwards (plinian if I'm right with the eruption type) so it gave an opportunity for the people to evacuate. Imagine if it erupted violently - it would be very hard to evacuate considering there are thousands living on it's caldera.

[@jakealter5504]

I’m not surprised that Vesuvius was in the top 3, it definitely deserves a high ranking

[@caiolucas8257]

It does, i was a bit confused on Twitter when Geology Hub put it that high, but i get it looking at it's historical eruptions and the fact the volcano never had a caldera collapse despite some VEI-6 eruptions, which makes me guess the volcano may yet have a magma emptying eruption. It also makes sense for it to be over the larger Campi Flegrei given Vesuvius has more recent eruptions while Campi goes into Fuji scenario as a long dormant volcano with catatrophic destruction potential.

[@KaiserStormTracking]

@@caiolucas8257 eruption frequency is what holds it back Vesuvivus is unlikely to have another caldera collapse due to currently being in the cone building phase of its cycle(Mount Somma, the base of Vesuvivus is very likely dormant) and vesuvivus only repersents the latest vent from Mt.Somma anyway chances of another caldera are pretty slim

[@caiolucas8257]

@@KaiserStormTracking I'm kinda unsure regarding the caldera thing, there's a lot of stuff we don't really know for certain about the Campanian volcanoes specifically regarding Vesuvius and Campi Flegrei, we don't know if they share the same magma chamber to a certain extent(i'm sure if they do Campi has more than 1 chamber). The Somma collapse i believe was either prior to the formation of Vesuvius or actually formed the Vesuvius. The actual Vesuvius cone is not known to have collapsed like Pinatubo despite being a VEI-6 volcano.

[@KaiserStormTracking]

@@caiolucas8257 Vesuvius is calssifed as a Somma volcano somma volcanoes form in a classic caldera eruption and then resulting post-caldera eruptions build a new cone like Vesuvius Campi and Vesuvisu/Somma as far as we know don't share a chamber. their location is likely pure chance

[@caiolucas8257]

@@KaiserStormTracking I know that, what i meant is that the Vesuvius cone never collapsed on itself. The shared magma chamber thing has never been confirmed nor rebuffed, it's similar to the Nyiragongo and Nyamuragira situation in the Democratic Republic of Congo. I mentioned the magma chamber because it has long been theorized that Vesuvius may just be part of the larger Campi Flegrei volcano rather than it's own thing.

[@StuffandThings_]

@@caiolucas8257 Taupo is very unusual in that it has produced a couple very large eruptions after a pretty short interval. A VEI 7 following a VEI 8 after less than 30,000 years is VERY unusual. Plus, if I recall correctly it inflated then erupted very quickly, much less warning than a typical massive eruption. And of course, quite a lot of people live nearby and its on an island where escape isn't the easiest. Very nasty volcano if it decides to go, thankfully there is still a good bit of time between eruptions and it had a large eruption relatively recently in geologic time. Probably one of the main things holding it back. Although the TVZ should probably be considered as one of the more dangerous volcanic regions on the planet.

Excellent video on most dangerous volcanoes. It is interesting how this list differs from the decade volcano list. Do the scores for Krakatoa, Tambora, and Rinjani take into account the likelihood of a caldera forming eruption in the near future? Since caldera forming eruptions occurred at those volcanoes relatively recently does it mean that it will be a long time before another large eruption? Since Iwo Jima is more likely to produce a large eruption than Tambora, Rinjani, or Krakatoa it is more dangerous than any of those volcanoes?

Nice video! Just a correction, Tarawera is just a vent of the greater Okatania caldera, which includes all of the rhyolite domes and volcanic lakes east of (but not including) lake Rotorua. It kinda overlaps with 2 other calderas, which is why we refer to the greater area as the Taupo Volcanic Zone, which at a stretch can be interpreted as one large volcano. Thoroughly recommend a video on the TVZ, it’s a unique situation and has produced many large eruptions.

[@GedMaybury23]

Kia ora, Michael. Thx for the additional info. (I'm from South Island; we're better at earthquakes down here!) I was quite surprised to see Tarawera on the list at place 10. Sure: in its time it was a monster and a killer. I guess the maths bumped it up on one of its sub-scores. I never think of it as a recurring threat, but more of a once-off event. Is there reason to see it as a likely player any time soon (geological-timescale 'soon')?

[@GeologyHub]

@@GedMaybury23 Tarawera/Okataina makes the list as it’s major eruptions frequently effect the global climate. One in the 1300s and one in 1886. Also, a lot of people live in the at risk radius

[@Pebblezcrwd]

@@GeologyHub the problem with Nz volcanology is most of our volcanic records are either poorly preserved or unstudied. The 25.3ka (VEI8) Taupo eruption/Oruanui event occured in the height of the glaciation, thus the estimation for the size is probably lower then the actual size. Unpublished data I know about for Okataina Caldera shows it is a lot more active then previously thought, however this brings it to the same level as Taupo Caldera, which (records-wise) seems to be a far more active volcanic centre.

[@Pebblezcrwd]

@@GedMaybury23 Okataina centre is a significant volcano, it's just the lime light is stolen by Taupo as it is better studied and the lake is significantly larger. Tarawera just seems to be where the two most recent eruptions have occurred

I’m actually very surprised to see that Mount Nyiragongo isn’t in the top 10; even though it’s eruptions don’t tend to be explosive they’re frequent, and also because of its very fast lava flows and the millions that live on its slopes And not to mention the danger of a limnic eruption from Lake Kivu whenever Nyiragongo’s lava reaches its shores.

[@caiolucas8257]

I think it's mostly due to low level eruptions and population density. The reason Japanese, Italian and Indonesian volcanoes appear so much on this list is because all 3 countries have large metropolitan centers with volcanoes nearby, their volcanoes also tend to be deadlier and much more powerful. The only exception is the odd Mount Etna, which has around the same VEI as Nyiragongo, but again the proximity to people's homes and much more frequent and deadlier eruptions puts it much higher than Nyiragongo.

[@caiolucas8257]

It is a shame Nyiragongo didn't make at least a top 30 because it poses a lot of danger, but on that note it's mostly due to poor volcanic monitoring. Africa's self governing countries still suffer the scars of colonialism and exploration and when you add that to corrupt political leaders things can be very bad. Meanwhile African volcanoes in European settlements such as Cumbre Vieja benefit from the European money and stability that results in better volcanic monitoring.

[@RolfStones]

Didn't expect Vesuvius to top Campi Fleigri. Because it erupts more frequently?

[@caiolucas8257]

I was shocked too because Campi Flegrei had larger eruptions, but Vesuvius had more frequent eruptions plus the actual deaths it caused has more empirical evidence(the skeletons in Herculaneum and Pompeii). Campi Flegrei is pointed to have been the fall of the neanderthal, but that is hypothesis scenario a la Toba causing a population bottleneck while Vesuvius has clear evidence of the destruction it caused.

I was looking at the Galapagos Islands and noticed several calderas that looked like rings left from former larger Islands plus lots of cones on the largest Island, Isla Isabela. I was wondering if any these are considered active? Were any large eruptions in the past?

[@Akechi_The_Phantom_Detective]

Bless you bud. Looking at Isla Isabella via it's Satellite Images there seems to be pretty strong evidence that a caldera collapse South West of the Vulcan Wolf. And blatant evidence of Lava Flows having reached the ocean from that volcano. I'm unfamiliar with the geology of the island but the visual evidence seems to support it.

[@gawe100]

what do you think about strato volcanoes that really close with each other? like vesuvius-campi flegrei, arjuna-kawi, sindoro-sumbing, semeru-bromo complex, etc. how they're form, or do they share magma chamber ?

[@GeologyHub]

This is an interesting topic. I do not yet have an opinion on the issue as it’s an area of geology I do not have enough knowledge in. I know of two such areas with ridiculously closely spaced volcanoes in Alaska; such as near Novarupta

[@rngalston]

Can't believe there aren't any in the top 25 from the Eastern seaboard of the US! But glad...

[@thegreenreaper6660]

Very nice video! The top-listing cán be debated though. Not to 'criticise' or 'mock' your fantastic Upload. On the contrairy! i'd like to start with commending you for your chosen 'standards' of determining. I find that a very good standard actually. Yet in terms of Effect, aftermath and 'population affected/at risk' and other hazardous catastrophes, there are plenty of other volcanos to also consider imo. To name a few: -Though highly dormant still, and activity sliiightly increasing, the Yellowstone Caldera is a threat of mónstrous proportions! But to be just as honest: the consequenses of ány YS-eruption are cómpletely off the chart in this Comparison. -Toba, like above... nuff said. -Kilimanjaro in Tanzania. Though not as deadly, a heavy eruption in this poorly developed area, could have longterm disasterous consequenses to the nation, and its neighbouring country's. -Mr Erebus on Antarctica. The 'mere' fact this reasonably active volcano is located in the dénse Icecaps of the Southpole, adds up a great danger to this volcano's true capability's. Perhaps not locally, the 'mixture' of volcanic lava, Ice and the immense 'chemical reactions' that occur when this 'beast' would come to a really big eruption, is nearly unimaginable for a global scale! Imo the consequenses of Erebus 'blowing up', have a same potential as the Samalas(Rinjani) and Tambora? -Ojos del Salado. Iirc the híghest volcano in the world, located on the border between Argentina and Chile?(not 100 sure). Ojos' is a big of the 'big brother' version of Rainier in the US. The Lahars that this gigantic monstrosity can produce, could wipe out very large areas in South America. Massive mudstreams, rolling down from ~7km altitude....BRR... dont even wna imagine that.. -La Cumbre Vieja, currently erupting on La Palma. Perhaps not the volcano itself, but like the Kilauea on Hawaii, this volcano can cause an énormous Landslide (a vast multitude of what occured when St Helens tore itself apart..), yet this is an Island-Volcano. Such a catastrophe would cause a MASSIVE Tsunami, affecting a véry large part of the bordering nations to the Atlantic Ocean!! -The Kurils. Though in a lightly populated area, Kamtsjatka, Russia, this ís a Supervolcano! Perhaps not the eruption itself, yet the aftermath would be devastating, comparable to Samalas/Rinjani, or Tambora... Krakatoa? -Fuego+Pacaya in Central America. Quite active, and plenty of populated villages around it. Fuego's last eruption caused plenty of death and destruction...and it still was only a light eruption. This area is 'saturated' with volcanic activity, hence i name both volcano's, to indicate the area... IT'd go as far up as: -Popocatepetl. A humongously LARGE towering 'demon', overlooking Mexico City, one of thé most densely populated citys in the world! Luckily, 'Big Popo', hasent erupted on a mássve scale, yet this dormant 'Hellhole' most définately has that potency. There are over 8.5M registered in habitants in Mexico-City alone... and fár more in the unregistered Suburbs and 'swallowed up' residences around it... Imo its not that crude an estimation that 'Big Popo', threatens well over 20M people? -Aira Caldera. Though you did correctly name an list Sakurajima. Sakurajima is but one of the mány vents, fed by this Supervolcano. Comparable to Lake Ilopango, which also feeds several Craters. Aira is surrounded by DENSELY populated areas in Japan. Sakurajima is the most active of the Aira-vents, but Aira itself is a dormant and terrifyingly dangerous Supervolcano!! -Long Valley Caldera. Though located in the more distant Death Valley-US, the eruption itself wouldnt affect that many people, This is a 'smaller'Supervolcano, like Campi flegrei: the Fallout of this volcano could affect ALL of California/LA. thats téns of millions of people! Iirc recent studies have indicated this sleeping giant is also sloooowly starting to awake fro ma very long slumber. A hideous idea to imagine... Also to not 'on forehand' exclude the possibility of the heavy seismic activity caused by a large eruption of this 'beast', could perhaps trigger seismic 'resonance' in the volatile San Andreas faultine??.. oof! Tháts just a catastrophe of unimaginable and unprecedented scale?.. ye, perhaps comparable on a scale of Toba/YS... Taupo? -Taupo Lake, New Zealand. The central lake of the south island... well its not a lake, the lake IS the depression of the Caldera... Like the immensly dangerous Taal.. Luckily this supervolcano isnt very active atm, yet it has an incredible potency! I think i read, one of the Taupo's bíggest eruptions; a VEI-8 Supereruption caused só much fallout, the entire island was covered in 200 feet: over 60 meters of Volcanic ash?.... Holy Sandwich-f*ck??? I could name a few more if i'd do some searching, but i'm curious :) From one fascinated Volcano-enthousiast to another! Do please reply! PS, Honorable Mention; -the Tamu Massif. located 'between Hawaii and Japan' in the middle ofthe Pacific Ocean. Though considered extinct, science cannot exclude that this 'énormous THING', simply takes hundreds of thousands, if not millions of years to build up and would even be able to cause "Flood Volcanism" (A volcanic scale that far, FAR exceeds whatever YS, Toba, Taupo, or évery other volcani in the world, COMBINED have ever caused! I think the only comparable measure would be what happens on Jupiter's Moon, IO. Roughly compared: Average IO eruptions START on a NON-earth scale of VEI 9 or 10... but 11's, or 12's occur there quite often as well. Luckily, IO is FAR far away from our planet... but just for comparison). Iirc the measurements of this Oceanic Volcano are around 350x400KM, and ~4.1KM in altutude, from the Oceannfloor, reaching approx 1.9km, under the sea surface. The Tamu Massif is a smaller version of the Martian Giga-Volcano, Olympus Mons. Science 'estimates', the last eruption of O.M. on Mars, literally KILLED the planet! - ??? The mysterious undersea eruption that caused the supermassive Pumicefield, of approx 20.000 footballfields in size, floating over the Pacific Ocean ,a few years ago. We dont know whát volcano caused it, but 'concluding' this was a 'mere Lava-spray' which was immediately cooled by the seawater, causing such an incredible production of Pumice... its frightening to imagine what this volcano could cause, would it blow its top off... Something that'll gréatly exceed the Tsunami that struck India, several years ago?

[@thegreenreaper6660]

Also, a 'statistical comparison' to give people a bít of an image of the INCOMPREHENSIBLE power of Volcanism; Tambora 1815! Now, to set a 'standard': Thé biggest Nuclear Bomb EVER detonated, was the USSR's Tsar-Bomba. detonated on 2km altitude above the island of Novea Zembla, north of Siberia. This megabomb caused a shockwave that went around the earth, 7x, and caused broken windows as far as Finland and Norway. Below the Detonation-area, a humongous 'Glass Lens' was formed from the superheated fireball that líterally melted the earth into a depression, approx 2km in diameter, 1m pressed below, or due to the melting, and a 'lens'approx 2M thick in the center... The calculated Blastyield of th Tsar was estimated on approximately 56 Megatons.... Now, coming to the Tambora Mega-eruption of 1815, that caused the Year without Summer: Science has calculated, that to blow up a volcanotop from 4350m, down to the current crateredge of 2800m, also leaving a crater of 1km depth from the edge(so 2.5KM of peak) and a 6km crater in diameter, an exposive force of ATLEAST 33.500 Megatons was needed! 33.500 Megatons.... Pun duely intended; This volcano didnt just blow its head off... realising those statistics in practise, simply blows your mind.

[@bigrooster6893]

I truly believe there’s probably be 3 volcanoes in Central America and South America that should be on that list

[@bob_frazier]

Does it seem like volcanoes are extra active globally right now? I would like to know if there is a scientific system that rates total global volcanic activity on a regular scale such as by day, week or month.

[@KaiserStormTracking]

Just the media and algorithm We are well within average

Would be cool to get videos on regional volconology. Like how and why Indonesia is so active and why it has so many vei 7 and vei 8 volcanos

[@GeologyHub]

Indonesia’s volcanoes are mostly due to the collision with the Australian plate, which moves about 7 cm each year. It’s the fastest moving tectonic plate on the planet, which causes high rates of subduction related volcanism

[@jakealter5504]

Indonesia does have multiple volcanoes that can go vei 6-7 but Indonesia has only one volcano that can go vei 8, it’s just that the one vei 8 volcano Indonesia has happens to be even larger than Yellowstone is

curious, where did Mt.Rainier in Washington State land on this list?

[@drscopeify]

USGS ranks it as #3 in the country. The main risk is Lahar as it tends to reach many of the cities in the area like Enumclaw all the way to the port of Tacoma. Settlement and recorded history in the area is relatively recent which makes it hard to asses but USGS has it ranked pretty much near the top. It is not as dangerous to people as Naples where people are living inside the Caldera but no doubt a Lahar is a formidable risk especially from a rare event form Rainer like the Osceola Mudflow event would impact a good number of people.

[@Trylobyte]

the relative positions of these volcanoes on the list is highly debatable and difficult to weigh up. I believe the effect on air travel shouldnt be too large a qualifying factor -I feel far less threatened by a closed airport than a pyroclastic flow!

[@jakealter5504]

That doesn’t really effect the top 3 on this list since all three are known for very violent eruptions and are close to major population centers
