What happens when a volcano erupts violently?
Explosive eruptions can send rocks, dust, gas and pyroclastic material up to 20 km (12 mi) into the atmosphere at a rate of up to 100,000 tonnes per second, traveling at several hundred meters per second. This cloud may then collapse, creating a fast-moving pyroclastic flow of hot volcanic matter.

How many people died when Krakatoa erupted in 2020?
Heard 3,000 miles away, the explosions threw five cubic miles of earth 50 miles into the air, created 120-foot tsunamis and killed 36,000 people.
How many times can a volcano erupt?
In theory, there is no limit on the number of volcanoes that could erupt at once other than the number of active volcanoes themselves: while it is thus theoretically thinkable, that all 600 volcanoes (on land) known to have had eruptions during recorded history erupt at once, this is so unlikely that it can be excluded …
What does lava smell like?
A bit like hot metal, say a soldering iron or a hot stove, a bit like regular stone, say a pile of dry gravel or concrete mix. Sometimes, especially right near the vent, there’s sulfur gases mixed into the lava, in which case there’s a strong sulfur smell, like overcooked hard-boiled eggs.
Can lava turn into a gas?
As magma rises towards the surface and pressure decreases, gases are released from the liquid portion of the magma (melt) and continue to travel upward and are eventually released into the atmosphere. Large eruptions can release enormous amounts of gas in a short time.
Can Krakatoa erupt again?
At some point in the future, Anak Krakatoa will erupt again, generating more tsunamis. Since it is difficult to predict exactly which areas of the Sunda Strait will be affected, it is of paramount importance that residents in coastal villages are well aware of the danger.

What is the volcanic eruption science project?
Volcanic Eruption Science Project. Although they are often a destructive force, volcanoes are an amazing facet of creation. Volcanoes erupt when magma, red-hot liquid rock, seeps up through a vent in the earth.
How can I demonstrate a volcanic eruption to my child?
You can demonstrate a volcanic eruption using some simple household items. Kids usually have a great time doing this experiment, and may want to repeat it several times! To make a big eruption, use a small plastic bottle (the size 20-oz soft drinks come in works well). Fill the bottle halfway (1 to 1.5 cups) of vinegar.
