Here are some facts about volcanoes where statistics and the measurement of height, volume, time and temperature (all forms of math) play an important role:

Height:

The largest volcano is Mauna Loa and it makes up part of Hawaii. The volcano stands above ground, but it begins way below the ocean and is actually 9090 metres high.

The tallest mountain in Africa is Mount Kilimanjaro and it happens to be a volcano. It is 5,895 metres high.

The ash-cloud over the volcano Hekla, in Iceland, rose to the height of 30 kilometres in 1947.

Fountains of lava rose up to 500 metres high from Askja, a volcano in Iceland.

The most lava and other volcanic material was discharged by the volcano Tambora, in Indonesia, in 1815. It released 150 cubic kilometres of lava and volcanic material.

Statistics:

There are about 485 active volcanoes on this planet.

One third of all volcanic eruptions take place on the island country of Iceland.

Research stations have been set up on 10 volcanoes.

The Earth's crust is 4.5 million years old.

The Earth's crust can be up to 50 km thick in some areas!

An eruption occurred through a man-made tunnel in a mountain called Kelud in Java, in 1919. It killed 5000 people.

In 1902, a violent eruption from Mount Pelee in Martinique killed 29,000 people.

In 1792, an eruption from Unzendake, in Japan, created volcanic mud that drowned 10,000 people.

The gigantic eruption of Tambora, Indonesia, caused the death of 10,000 people. Then 80,000 died due to starvation.

When the island of Krakatoa erupted in 1883, it caused a tidal wave that killed 40,000 people. The island sank after ejecting 18 cubic kilometres of lava.

Time:

Moving lava in Hawaii has been clocked at 10-300 metres per hour. Get out of the way!

Temperature:

Magma is molten rock and it is comes from the center of the earth where the temperature can reach up to 10,000 degrees centigrade. That's extremely hot!
