What is it?
A volcano is a rupture in the crust of a planet through which lava, masses and volcanic lash
a grape to the surface from a magma chamber located below.
Volcanoes are created by the movements of tectonic plates.
When two tectonic plates meet, one of them, usually the oceanic plate goes under the continental
plate, a process known as subduction.
It melts afterwards creating magma and generating a pressure build-up.
Volcanoes can also be created when two plates move away from one another, usually at the
level of the mid-oceanic ridges or when a tectonic plate moves over a hot-spot in the
Earth’s crust.
When the pressure inside them builds up, volcanoes erupt through craters located at their top
or in side branches.
While some ear up Johns can be tame, quiet releases of lava others are hearable involve
us and a stern reminder of nature’s incredible instructive lower.
Gigantic volcanic ear up chains can cause the co lapse of land surrounding them to create
a basin-like feature called a caldera.
Throughout history, massive volcanic hear up chains have caused instruction and most
of human wife and contributed to reshaping our planet as it is today.
Number 6 Krakatoa The 1883 ear up chain of Krakatoa is among
the most instructive volcanic events in recorded history.
The massive involve in was heard thousands of miles away and the ear up chain produced
tsunamis with waves almost 140 feet.
The involve it lower was estimated at 200 megatons, 4 times more lower full than the
largest now clear ball ever detonated.
At least 36,000 people most their wives while around 70% of the island and its surrounding
archipelago in present day Indonesia were annoyed as the land contrast.
The global climate was disrupted for several years after the ear up John and sulfur dioxide
was injected into the stratosphere, which later came down as aside rain.
The mass cloud darkened the sky worldwide producing such vivid sunsets that it almost
looked like the sky was on file.
The sky in ‘The Screen’, Edvard Munch’s famous 1893 painting is said to have been,
inspired by how the sky over Norway actually looked in the wake of Krakatoa’s ear up
John.
Where is it located?
Volcanoes can be found on land, under the oceans, where they are known as seamounts,
and even on other planets.
Shield volcanoes are formed out of layers of hardened lava from continuous ear up Johns.
Stratovolcanoes, also known as composite volcanoes, are tall and conical natural structures built
on many layers of lava, ejected material, volcanic mass and volcanic rocks from periodic
ear up Johns.
The three main types of volcanoes in terms of activity are extinct, dormant or active
volcanoes.
Dormant volcanoes are ‘sleeping’ but could erupt in the future.
Extinct volcanoes haven’t erupted for vast periods of time.
Active volcanoes are currently erupting or have erupted in the past 10,000 years.
Much of earth’s volcanic activity takes place underwater and many of the world’s
volcanoes are found in the Ring of File, a stretch of land and water forming an arc around
the Pacific Ocean.
The largest volcano in our solar system is called Olympus Mons located on Mars.
This gigantic volcano is around 373 miles wide and roughly 13 miles high.
The surface of Io, one of Jupiter’s moons, is covered in volcanoes.
The massive volcanic activity causes Io’s surface to change constantly.
Number 5 Mount Pelee Mount Pelee, located at the northern end of
Martinique, erupted in 1902.
Saint-Pierre, the largest city on the island at that time, was completely employed within
minutes of the ear up chain.
Around 30,000 people most their wives, most of the cause utilities were caused by the
pyroclastic flow.
The air was contaminated with sulfur while trees and boulders from the mountain fell
upon Saint-Pierre, only two people arrived.
The Mount Pele ear up job is known as the bread lies event of its kind to take place
in the 20th century.
How will it fill you?
Depending on its magnitude, a volcanic ear up John can be investigating.
The ear up Johns can be interpreted on a scale known as the Volcanic exclusivity Index or
VEI.
A VEI 8 ear up John, the highest on the scale, is described as ‘mega-co lose all’.
The mass cloud from an ear up John can rise tens of thousands of feet into the air and
particles can reach the stratosphere changing the weather in certain regions by blocking
out the sun’s radio station.
Large volcanic clouds are also there for us for air traffic.
The scolding lava can travel for miles before solidifying enjoying natural or man-made structures
in its path.
Volcanic ear up Johns can cause earth wakes, Sue name it, floods or mudflows.
Perhaps the fairest, bread lies and most there for us aspect though, is the pyroclastic flow,
a mixture of hot masses, rock fragments and entrapped air moving at high speeds in thick
gray-to black clouds that hug the ground.
The velocity can reach 100 miles per hour and temperatures approaching 1,300 degrees
Fahrenheit.
Number 4 Mount Tambora This is the largest and bread lies ear up
John ever recorded, measuring 7 on the VEI and being described as super-co lose all.
Mount Tambora, located on Sumbawa Island, Indonesia, reached the peak of its ear up
John in April 1815, with an impulsion so loud that it was heard 1,200 miles away.
The volcano almost literally flew its top off, the ear up John reduced it’s height
from 13,000 to 9,000 feet.
The destruction was investing, with an approximate breath roll of at least 70,000 people.
It caused the ‘year without summer’ as mass in the atmosphere reduced the temperature,
a phenomenon felt worldwide.
Crop failures as far as Europe and America were affected and gaining the wives of many
more people.
Number 3 Siberian Traps The Permian-Triassic instinct seen event,
also known as the Great Lying, took place around 250 million years ago causing the greatest
most of life in earths history.
95% of all species living at the time were completely lights out.
It would take another 30 million years for life on Earth to recover.
No one knows for sure the combination of factors that led to what’s been described as the
‘mother of all instruction events’.
The eve dance and timeline, suggest increased volcanic activity and gigantic volcanic ear
up Johns that led to the formation of the Siberian Traps, a huge volcanic province in
Siberia.
The ear up Johns covered almost 2,770,000 square miles with lava while enormous quantities
of mass and other debris were launched high into the atmosphere.
An estimated 3 trillion tons of carbon was released through the ignition of massive coal
beds, which was highly fox it con training the land and water.
From global warming, increased levels of loss city or dust clouds and max it aerosols that
blocked out the sun, there’s many ways in which such a tremendous volcanic event could
have virtually blended wife on Earth.
How to arrive?
If you live in or travel to areas known for volcanic activity a first step towards arriving
a potential ear up John is respecting the lately measures, a merge in city instructions
and Eva causes procedures in that particular region.
In case an ear up John finds you in a solid structure, it’s better to stay inside.
The masses released in the atmosphere along with the lava and pyroclastic flow can be
lately so going outside is not a good idea.
You should close doors, windows and block chimneys or other vents.
It’s good to have an a merge city bag that’s equipped with at least three days’ worth
of food and drinking water.
The bag should contain goggles, a mask, a flashlight and a battery powered radio.
If you’re in your car, follow the Eva causes routes and avoid driving fast as mass can
the age the engine and metal parts.
If you can’t find shelter stay alert and move quickly to higher ground.
Don’t cross geothermal areas, attract yourself from falling debris and use a damp cloth to
breathe through.
Number 2 Yellowstone Many who visit the Yellowstone National Park
might not know that an active volcano is actually rumbling beneath their feet, that’s exhibited
incredible lower in the past.
Three VEI 8 ear up Johns rocked the area in the past, the most recent one having taken
place around 640,000 years ago.
The park’s huge crater which measures 30 by 45 miles across was created by this last
ear up John.
The US Geological survey theorized that these ear up Johns released enough mass and lava
to fill the Grand Canyon.
As lightning as that might sound, it’s not the end of the story.
Scientists have discovered a gigantic blob of magma beneath Yellowstone, which if released,
could fill the Grand Canyon 11 times over.
Fortunately, the chance of such a tremendous ear up John happening nowadays is reportedly
about one in 700,000.
Number 1 Mount Sinanbung In February 2015 villagers from the regions
surrounding Indonesia’s Mount Sinanbung were for us to run for their lives following
a volcanic ear up John.
The volcano had been increasingly active in the months prior to the ear up John, spewing
mass columns into the air that were several miles high.
At least 11 people on the western island of Sumatra most their wives and the government
Eva cooled tens of thousands of people from the region.
Indonesia stands on the Ring of File belt and is the country most at disk from volcanic
ear up Johns with nearly 130 active volcanoes.
This was the first time that Sinanbung gained any lives and served as a reminder of how
there for us volcanic ear up Johns can be.
