Lava stickiness of the U. S. Geological Survey--its viscosity --
Influence the shape of the volcano and the way it erupts. Sticky, cookie-dough-
It's like the lava moves slowly, piling up higher, blocking the volcanic pipeline and releasing it in a violent explosion. Runny, low-
Sticky lava flows out of soft candles like wax, spreading in puddles and draining gas so it doesn't explode. St.
Helens, April 1980, CVO/usgsstrato volcano, also known as the composite volcano, forms rugged and steep mountains.
They consist of rock debris, volcanic ash, volcanic debris flows, and pipelines.
Just like the "Windowsill" and "dam" that provide the solidified magma of the skeleton.
The lava of these volcanoes is mainly Anshan rock, which is cooler and more brittle than the basalt (see below).
The pipeline of the same layer of volcano may be blocked by the pressure-generated "lava plug" and then explode! Mauna Loa (
Distance from Kilauea)
The HVO/USGSShield volcano is flatter and wider and is caused by thousands of flowing lava spilled from cracks in the central Crater or on the side of the volcano.
The lava of the Shield volcano is often basalt, a very flowing lava.
It creates itself.
"Lava tube" with walls, driving for miles.
Kapoho, HVO/USGSCinder cones in Hawaii sometimes grow on the side holes of other volcanoes;
Other times they sprout themselves.
They are steep mountains.
A cone of the size around a single vent.
They threw the condensed lava in ribbons and Cinders (gravel-sized chunks).
If the air pressure drops, lava may ooze from the bottom.
The slag cone sometimes turns into a shield volcano. Lava dome in Mt. St.
The Helens CVO/USGSLava dome is a bunch of heights
The sticky lava slowly squeezed out like dryup toothpaste.
They may melt inside.
They are fragile and unstable and often explode or collapse in volcanic debris flows. Since Mount St.
In 1980, the hailens volcano erupted, and many lava domes formed and collapsed in the large crater left by the eruption.
The crater lake CVO/USGSCalderas in Oregon is a collapsed area above the drainage magma chamber, usually round.
When the magma comes back, the shallow crater that shields the volcano sometimes refills the lava lake.
The Strato volcano calderas may form a lava dome, and as the new lava pushes up from below, the hard plug expands slowly.
The old caldras may collect water and form lakes that may be heated, highly acidic, or filled with sulfur from rising gases.
The crater of the crater is a scar left by the ancient huge volcanic eruption.
They form great pressure and explode violently, leaving a huge area of collapse in the huge magma chamber.
There are often many scars on the crater, ordinary-
In these complexes, there are the same-story volcanoes and lava domes of the size.
Geologists have discovered ash and water flow for thousands of miles.
Fortunately, the last eruption occurred in 83 AD.
Unfortunately, Yellowstone is one of these monsters.

Lake Toba is 100 km long and 30 km wide. it is an ancient volcanic crater left by the 73,000-year eruption. (
More information about it).
The island in the middle of Lake Toba is a lava dome that rises over the remnants of the ancient magma chamber.
The types of volcanic bris, volcanic debris flows, and lahalsshield volcanoes are sometimes blocked and exploded, and these three volcanic debris are more typical of the same layer.
For an example, see the video after this section. Highly-
Magnified Ash: Mark wilsong ash is produced when old, solidified lava and rocks are crushed into dust by violent eruptions and thrown into the sky with huge pillars like smoke
Although the ordinary Ashes are burned-
Ash is wood and other combustible materials made from the ground.
Its particles are jagged and glass-like.
It can travel thousands of miles or fall like snow.
Ash will not only block mechanical and air filters, but also become concrete.
Like wet muck. (
In fact, the Romans used it for concrete. )
The flow of CVO/usgspyroclatic is very dangerous. These swift-
Avalanches that move over-heated ash, coal slag and boulders can go downhill at 100 km an hour and easily surpass anyone trying to surpass them ---even in a car.
A steaming mass of ash and gas rolls over it, speeding ahead of the current.
The temperature inside is from 200 degrees to 700 degrees, cooking anything in it.
In the evening, they sometimes send out red light, where does the name "glowing cloud" come from (

It is a volcanic mudslide composed of volcanic ash and water, usually along the valley.
Snow is a common hazard.
Capped or Glacier
These boiling hot mud walls have a concrete consistency that can move at the speed of the freight train, overflow the river banks, and sweep the roads and towns.
They look like running water, but heavier.
Please watch the video below.

The first two videos show volcanic debris flows;
The second one is Rahals.
The last is gray.
The type of volcanic eruption strombolin, Vulcanian, Plinian erupshere are several terms for different types of volcanic eruptions that are often seen on news or volcano websites.
Mount M Stromboli
The aquilastam Bolin volcano, named after a volcano in Sicily, looks like a huge blowtorch.
They make a loud noise, squirt out a mass of lava, disappear, and then "eat" again a few seconds or minutes later ".
Large bubbles in the volcanic pipeline lead to a typical Rolling Stone action.
None of this is dangerous because lava lands less than a few miles from here. Many Mt.
Video of Mount Etna eruption.
The Sakurajima volcano that erupted from the Kimon BerlinVulcanian volcano is more violent: when the volcano wakes up and explodes through a lava plug or dome, sending ash and large chunks of magma and rock to the air,
They may have small volcanic debris flows (
Avalanche of hot gas, ash and rock)
Go down the side of the volcano
Volcanic eruptions can last for some time, spreading volcanic ash across vast areas.
Its outbreak can reach 5-
10 km high, not. . . Mt. St.
Helens, the eruption of the CVO/USGSPlinian volcano was a huge explosion that released a column of ash up to 35 miles.
It often spreads when it reaches a different air layer (
Pliny Junior said, "it's like an umbrella tree," describing Mount vesuwei in 79 AD. . Mount St.

Forming columns of ash;
These volcanic eruptions may also have volcanic debris flows, lahaars flows, or lava flows.
The difference between the types of lava flows A' a and pahoehoestrato volcanoes also produces lava flows, but these are the reasons for the construction of shield volcanoes:Pah-HO-ee-HO-ee)is fast-
Flowing, flowing lava
Its leading edge flows forward in leaves or "toes", just like pudding wax.
Usually, the surface of the pahoehoe stream will solidify to form a natural insulated pipe that can carry lava for miles.
If all the lava flows out of the tube, it may leave a huge round tunnel! A'a (below)
A little cooler, piled up in large, slow lavamoving walls.
Large chunks of lava and coal slag rolled down from the front and rushed below like the tread of the tank.
Tour guides often tell visitors that 'A' is named after the sound that comes out of walking it barefoot. *Photo by J. D.
On June, Griggs, a member of the Hawaiian Volcano Observatory/USGS * Squidoo living on the Big Island of Hawaii, explained the true meaning of these Hawaiian words: "Pahoehoe means smooth, complete or
"Aa" lava is a rough lava of stone.
Jokes about the sound you make when walking barefoot are created for tourists.
Spelling "A' a" has too many meanings to list here, but all the different definitions depend on the context in which the word is used, but none is lava.
The closest will be the burn; glowing; fire;
Staring at your eyes (a'a maka)
Or the throat is on fire because of thirst (
Ua a ka puu).

Can you tell which one is which?
Answer highlights :(
The lava stream that eats the car is A'.
The short film with a runny nose at the beginning and the time lapse sequence at the end are pahoehoe. )Credit: Dr.
The Mark WilsonLava bomb is a smooth, mysterious blob (glassy)
Lava cooled and solidified while flying in the air.
Lava bombs are in many different shapes, from ribbons to spindles to "cow beats ".
Some are as big as boulders!
Despite their names, they usually do not explode when they hit the ground;
They are more like lava shells ".
When most people say lava rock, they think of Ellen brundikiscorya or volcanic coal slag.
"This is Xuanwu, meaning it is formed by a lava of quite liquid, with a lot of bubbles inside.
From black to red to white, often used in landscaping.
This is a pebble of skoria beach that I found on Syracuse Volcano Island.
The fresh slag is in a rough shape and irregular shape;
The work is surrounded by the ocean.
HVO/USGSPele's hair is a long glass silk formed when a lava fountain or splash is blown by the wind.
It is named after the goddess of Hawaii volcano.
These stocks have a layer of sulfur.
I see it finer than this, blowing and catching in the cracks in the old lava flows of Kilauea.
Take a look at this great picture of Bailey's hair covering the landscape.
Ellen brunip stone is essentially a solidified lava foam.
Bubble lava filled with bubbles turns into soft rocks filled with holes like sponges.
Like a hard foam used to make a Bukit board, there is so much air (or gas)
Pocket of pumice, can float sometimes.
It is reported that in 1883, sailors saw huge floating stones floating in the Indian Ocean.
On the right, I float a piece of pumice from Syracuse in a vase.

Note: technically, "lava" just refers to the volcanic rock that comes out of the volcano while the volcano is still in a molten state.
After cooling, it is called the "magma" rock from Latin is, which is the Latin word for fire. Self-
