What is a volcano?
What is it?
A volcano is an erupting volcano.
A volcano erupts to release lava, sand and rock that travels down a hillside and falls to the ground below.
What makes a volcano unique is that the lava and rock are so hot, it melts almost instantly.
The rocks also contain high amounts of calcium carbonate, which is necessary for calcium carbonates to form.
A lava flow is formed when hot lava is pumped down the hillside.
How big a volcano is depends on many factors, such as the height, the type of rock it’s in, the location of the lava flow and how much pressure is exerted.
A typical eruption can reach about 25 metres (82 feet) in diameter.
Some are more than a kilometre (0.6 mile) long.
A few eruptions are so large they are considered supervolcanoes.
How can I find out if a volcano has erupted?
Check the eruption maps in the national park area.
If you live in a designated national park or an area of national significance, you can visit an area ranger and see the eruption map to make an educated decision.
If the volcano is visible, you should check the official eruption maps.
If there are signs that the eruption has happened, the volcano might have erupted.
You should also ask for a map of the area and any road signs or other warnings that may have been placed.
Some people find that they can identify the volcano’s activity by seeing its location on a map.
The official eruption map is published every 10 years and is available on the National Park website.
Are there any other ways to find out about volcano activity?
