If a volcano crater is filled with magma, this can travel a considerable distance.

US geologists were monitoring a large area around a volcano in Nicaragua with radar measurements from satellites.

It turned out that the magma caused over 6 miles of elevations of 6-7 centimeters.

Surveillance is therefore required over large distances.

2. Volcano releases gases from glacier

The Icelandic volcano Katla releases a lot of the greenhouse gas methane from the Sólheimajökull glacier.

The gas trapped under the glacier rises in the atmosphere as the ice melts in the heat of the volcano.

In the summer, 41 tons of methane gas are released every day - that's the emission of 136,000 cows.

3. Crystals predict volcanic eruptions

Small crystals form in liquid lava that determine how an eruption develops.

English researchers discovered that if the lava contains few crystals, the eruption proceeds quickly and the lava spreads quickly and far.

So if lava is examined on time, it can lead to better evacuation plans.

4. Shale oil was caused by eruptions

Geologists suspect that the shale oil that is in the ground was formed in North America 100 million years ago by volcanic eruptions.

Shale oil is a thin layer of petroleum in rock. The volcanoes probably brought nutrients to the surface, causing the amount of microbes to explode.

They are now oil.
