Pyroclastic Flows: The Hazard (VolFilm)
Вставка
- Опубліковано 8 тра 2019
- This film has been produced through the VolFilm Partnership. It describes the hazard that volcanoes generate called pyroclastic flows. Find out what they are, how quickly they move and the properties they have that make them so dangerous and deadly.
VolFilm is funded through the Challenge Fund: a partnership between the World Bank’s Global Facility for Disaster Risk Reduction and Recovery (GFDRR) and the UK Department for International Development (DFID).
St. Vincent has volcanic eruption has now moved into this phase. Lord be with them.
😓
Lord be with our lil island
Praying for SVG 🙏🙏🙏
St.vincent is now going through this phase🙆♂️ I came here to get a better understanding of what is actually happening. Thank you
Thank you for posting this informative video, because it helps me understand pyroclastic flow much better.
St Vincent going through this now🙏
Happening right now in my home country! Everyone be safe in SVG! #LaSoufrière
St. Vincent is going through this phase now... pray that everyone is safe
Thank you so much for posting this informative video
"Death or severe injury is certain for those caught by a pyroclastic flow." You can just omit the "severe injury" part. No one actually directly hit by a pyroclastic flow is getting any outcome other than nearly instant death. There is no close call or survival condition with 1000-degree molten rock, gas, and ash.
Severe injury is right, 1883 Krakatoa eruption saw some survivor from the pyroclastic flow, in an area of 3.000 people, 1.000 died from pyroclastic flow. The reason for that is the gas loses heat because they travel through the sea before reaching inland. Survivors are badly burnt with their skin melted and peeling off.
There's a book detailing this event by firsthand accounts and official accounts from the Dutch government.
Wow, thank you for this wonderful video. We are going to use it for our lessons on volcanoes. Do you have videos on other geologic topics? Thank you in advance.
This has gotta be one of the WORST ways to die….Not only are you scorched alive, but you are forced to breath in extremely toxic gas, and painful rocks/debris…this is exactly what happened to Pompeii…
Yep.
Apparently it’s instantaneous though, so you wouldn’t even know what hit you by the time you’re dead. Imagine cooking at 1,000 degrees in 3 seconds flat. Definitely not a fun way to go either way. 😬
Mt. Rainier has a well established 'lahar basin'...there have been many pyroclastic flows in the Nisqually valley.
The Town of Nisqually has a Lahar Surfing Club...members of the Club keep surfboards on the roofs of their homes...
Lord please cover St. Vincent and the Grenadines in this time.
...Taiwan....22 eq offshore in 48 hrs. Apr.24... On a known volcanic ridge. What might it look like next?
I’ll never know why people build homes around volcanos. At the least be like 3 cities away minimum.
Because of the long timescales associated with volcanoes. It can be 1000 years plus before an eruption and in that time 2-3 generations of humans would have lived safely in the area. Volcanic slopes are good for agriculture and villages would grow in size close to the farming grounds. Proper emergency plans and education is key to reducing the risk from volcanic hazards.
Pompey...Kracatoa ..Mounth St Helens....so dreadful 😮
I think a cellar or nuclear bomb shelter might be a good way to survive
...fatalistic condition (scenario), coming from behind. Faster than you can run. Doesn't pick me up off the ground?....and throw me, 1.5 (imetrick miles) to the ground...downrange?
Just stand in front of them like Galadriel in Rings of Power. You'll be fine lol
She drank lots of seawater right before it hit.
Wich volcano is at 0:59?
Now this is what the dust cloud at the wtc looked like which contained tremendous amounts of heat from the use of nuclear explosive devices contained in the basement which were blown upward through the buildings breaking the concrete floors and separating the exterior walls from the interior supports.
The mushroom cloud was contained in the building, but the resulting heat formed something very much like this pyroclastic flow into the streets below. LLXIIX77
The mushroom cloud from a nuclear explosive wouldn’t be contained in the WTC building. Plus, you would see the bottom of the building blow outwards before the collapsing top floors ever reached the upward expansion. Old school nuclear weapons using straight fission as a means of energy reach temperatures of 180,000,000 degrees F within the bomb casing and the isothermal sphere approx. 60 ft across reaches around 18,000,000 degrees F before the supercritical shockwave weakens enough for hydrodynamic flow to match the radiation driven shock front at approx. 1.8 million degrees F. At this point the fireball may be around 100 meters in diameter or more depending on the size of the fission detonation.
Modern thermonuclear devices (meaning since the 1960’s) reach internal temperatures up to, and in excess of 630,000,000 degrees F depending on the size and number of thermonuclear fusion stages.
During the actual WTC collapse of each tower, you can clearly see the the top floors collapse and begin spilling outward, making room for the energetic layers of newly pulverized concrete and metal to expand from the downward pressure of collapse.
Were you dropped on your head seven times as a child, or only the first six?
How do yu kno if yu live near volcanoes?
Just more then 20km? make that more then 40km in some cases..
Absolutely I live next to Mt Taranaki and this has been capable of upto 40km pyro flows with mountain side collapses happening 5 separate eruptions over 135,000 years
Volcanoes kinda sketch bro
ohh so thats why nc vid but is danger
Edna, is that you? Where is ma Suppa Suit?
That's why this person sounds so familiar! You nailed it
Bars
Pompeii
Bye
You niggas know my pyroclastic flow
Hello
Hi
Hi
That's where the government hides the aliens, inside dormant volcanoes. Well, hope you won't get stuck behind a Prius while escaping pyro-flows.
