Magma builds up in the mountain and starts to rumble. Then the rock at the bottom starts to push up causing the magma to go up and rise the temperature of it. As it nears the opening it becomes lava and turns into ash as it burns up.
You get a rather large explosion.
-Avoid areas downstream of the volcano-Listen to emergency information and alerts-Protect yourself from falling ash-evacuate ASAP-Avoid crossing bridges
An ash cloud is something which comes out of the volcano
No, an ash fall is not a volcano. An ash fall occurs when volcanic ash and debris are ejected from a volcano during an eruption and then carried by winds to surrounding areas, causing the ash to fall to the ground.
The volcano that has caused the ash cloud is called Taal Volcano, located in the Philippines.
There are two ways a volcano can produce an ash cloud. In most cases gas-rich magma rises inside the volcano. The gas is dissolved in the magma under pressure. As the magma approaches the surface the pressure decreases and the gas is released and expands rapidly, producing an explosion. The magma is blasted apart into tiny particles, which we call ash. The hot gasses then rise, taking much of the ash with them. In other gases, water inside a volcano may come in contact with magma or rocks heated by magma, causing steam explosions. These explosions pulverize some of the rock inside the volcano, during it into ash.
The word "eruption" can be used to describe a volcanic explosion. It refers to the violent release of magma, gases, and ash from a volcano. Eruptions can vary in intensity and can have significant impacts on the surrounding environment and communities.
If a "super volcano" erupted, depending on how big you are actually talking, the immediate area of the volcano would be engulfed in ash, rock, and of course lava. If you survived that the ash cloud would kill you. If the eruption was big enough, the ash cloud could cover half the world or even more and it could cause an ice age to happen in the future that could kill off the rest of the human race if they were not prepared.
The word you are looking for is "eruption." It refers to the sudden and violent discharge of magma, gas, and ash from a volcano.
Volcano ash hazard can be dangerous.
A volcano rock is rock formed from ash or lava erupted from a volcano.
The Krakatoa haze refers to the atmospheric effects caused by the eruption of Krakatoa in 1883. The explosion injected large amounts of ash and sulfur dioxide into the atmosphere, leading to colorful sunsets, cooler temperatures, and vivid twilights around the world in the following months.
