Five of the World's Deadliest Volcanoes

  • Thread starter Astronuc
  • Start date
In summary, this article talks about the five deadliest volcanoes in the world and their dangers. Kilauea is active and has been for some time, while Changbaishan is a volcano that few people know about in a remote part of Asia. It is also potentially the most powerful of the set. Thera is also high on my list, as is Mount Pelée.

I happen to stumble across this article: The world’s five deadliest volcanoes … and why they’re so dangerous
https://theconversation.com/the-worlds-five-deadliest-volcanoes-and-why-theyre-so-dangerous-74901

It's either that folks live near the volcano, or folks visit.

KILAUEA has been active for some time now, and lava apparently is routinely flowing to the ocean.

https://www.nps.gov/havo/planyourvisit/lava2.htm - one can visit, but there are areas on/over which one should not walk.

I didn't know about the fifth one: Changbaishan, China
Few have heard of this volcano in a remote part of Asia – and its last eruption was in 1903. However, its history tells a rather scarier story. In around 969AD, the volcano produced one of the largest eruptions of the last 10,000 years, releasing three times more material than Krakatoa did in 1886.

Edit: Changed title of thread to be more accurate. The title was "World's Five Deadliest Volcanoes".

I didn't either. It's potentially the most powerful of the set and it's right on the China/North Korean border.

I find this criterion "volcano" a bit strange (my opinion). I assumed to find the Phlegraean Fields instead of Vesuvius and definitely Yellowstone, and Anak Krakatoa as the headline, not Krakatoa, but this might be hair splitting. You are right

which doesn't affect much people (maybe with the exception of Naples and Popocatepetl). As far us I know, a major eruption of Anak Krakatoa could affect us all, and definitely Yellowstone and the Phlegraean Fields would, plus propbably some less famous plumes.

yup, I felt the same way with Anak Krakatoa and primarily its predecessor being the only really deadly one in that list
there are many other seriously dangerous / potentially dangerous volcanoes to consider. Two of which fresh_42 pointed out ...
Vesuvius and definitely Yellowstone

+ Mount Tambora

The Volcanic Explosivity Index goes up to 8. On that scale, the 1815 eruption of Mount Tambora rates a very destructive 7. The explosion took place on the island of Sumbawa (then in the Dutch East Indies, now in Indonesia) and plunged the region into darkness, but its effects were anything but isolated. Tens of thousands of people were killed by the apocalyptic eruption, subsequent tsunamis and ensuing starvation and disease. The largest volcanic eruption in recorded history changed the world's climate so much (even crops in Europe and North America failed) that 1816 became known as "the year without a summer." Tambora itself shrank several thousand feet and traded its peak for a massive crater at its summit.

Thera would be high on my list

Some 3,500 years ago, an event of cataclysmic proportions rocked the Mediterranean. The volcano at Thera (later known as the Greek island of Santorini) exploded with what is estimated at four to five times the eruptive force of Krakatoa in 1883, blowing a hole into the Aegean isle and sending out shock waves that, according to historians, would reverberate for centuries to come. The great seafaring Minoan civilization, the dominant Greek culture of the time, potentially withered away after clouds of ash enveloped its cities and great tsunami waves smashed its fleets. Stories of a world-shaking eruption linger in legends across the Mediterranean.

Mount Pelée

Mount Pelée, standing more than 4,500 feet high on the French Caribbean island of Martinique, erupted violently in May 1902, killing nearly 30,000 people — effectively the entire port city of St. Pierre. The catastrophe was so devastating that the term pelean — to describe that particular kind of ash, gas and fiery cloud eruption — became part of volcanic vernacular. There had been warnings of steam, light Earth shocks and raining ash, but they were ignored. After the town was wiped out, Pelée went dormant for some months, until geologists discovered a lava dome, dubbed the tower of Pelée, that rose to more than 1,000 feet above the crater floor before eventually crumbling in March 1903.Dave

I was thinking about Tambora (Indonesia) and Pinatubo (Philippines), and also Huaynaputina (Peru).

Here is a list of deadliest volcanic eruptions on Wikipedia: https://en.wikipedia.org/wiki/List_of_volcanic_eruptions_by_death_toll

https://volcanocafe.wordpress.com/2012/06/10/the-pain-filled-issue-with-ischia/

This blog is several years old but, IIRC, uplift continues. Ischia's dormant central volcano has the potential to kill many, many people, many ways. Land-slides, flank eruptions, flank collapses, pyroclastic flows etc etc. To paraphrase the technical detail, if it makes trouble suddenly, there's nowhere to run. Worse, the entire Bay of Naples area is horribly vulnerable to any Eastbound debris or tsunami...

interesting article, thanks for sharing :smile:

The wonderful things about vulcanology these days is that unless a volcano is completely unmonitored,
it's difficult to get caught off-guard. Monitoring volcanoes of interest means that they give early warning
of possible impending activity ... magma movement = harmonic tremor and other many small quake
swarms would announce a warning :smile:

The real problem lies in that many countries don't have the funding available for such
studies/monitoring -- and unfortunately Italy is a classic example of this.
And this is how the population can get caught off-guard by " sudden trouble" :frown:
It wasn't really sudden, the precursors were just not being monitoredDave

If the Phlegraean Fields erupt, no warning will ever be early enough: you cannot evacuate over three million people. I'm not sure your information about funding is correct, as the major ones (Phlegraean Fields, Vesuvius, Stromboli, Etna) are certainly monitored. At least I've seen the measure points on tv. But what is really bad is, the following story (no fake):

just a noted generalisation in 3rd world / economically not well off countries

If there is monitoring, and their may well be ... wouldn't be surprised if it isn't funded by USA and other better off countries
Italy has a huge financial problem that is well known

fresh_42 said:

yeah, I'm well familiar with that history and it is partly what comment the way I did ... tis very unfortunateDave

But Italy has the fourth largest economy in Europe, and eighth worldwide, ahead of Spain or Russia.

FAQ: Five of the World's Deadliest Volcanoes

What are the five deadliest volcanoes in the world?

The five deadliest volcanoes in the world are Mount Tambora in Indonesia, Mount Krakatoa in Indonesia, Mount Pelee in Martinique, Mount Vesuvius in Italy, and Mount St. Helens in the United States.

What makes these volcanoes so deadly?

These volcanoes are considered deadly because of their past eruptions and the potential for future eruptions. They have a history of explosive eruptions and have caused many deaths and significant damage to surrounding areas.

Where are these five volcanoes located?

Mount Tambora is located on the island of Sumbawa in Indonesia. Mount Krakatoa is located in the Sunda Strait between the islands of Java and Sumatra in Indonesia. Mount Pelee is located on the island of Martinique in the Caribbean. Mount Vesuvius is located in Italy, near the city of Naples. Mount St. Helens is located in the state of Washington in the United States.

When was the last major eruption of each of these volcanoes?

The last major eruption of Mount Tambora was in 1815. Mount Krakatoa's last major eruption was in 1883. Mount Pelee's last major eruption was in 1902. Mount Vesuvius' last major eruption was in 1944. Mount St. Helens' last major eruption was in 1980.

What are the potential hazards associated with these volcanoes?

The potential hazards associated with these volcanoes include pyroclastic flows (fast-moving hot gas and rock), lahars (mudflows), ash fall, volcanic gases, and tsunamis (in the case of coastal volcanoes). These hazards can cause damage to infrastructure and harm to human life.
