What is volcanic activity?

Volcanic activity is reflecting how often a volcano erupts, if at all. Some volcanoes are erupting often, others haven't in centuries and finally, some have not been erupting in thousands of years of even since the Ice Age.

Scientists classify the volcanic activity on a three levels scale. The levels are: active, dormant and extinct. An active volcano can erupt on a regular basis or periodically, for example, every ten years. The dormant volcano can be inactive over a long period of time, for example over a century and then all of a sudden, it has an eruption. The extinct volcano has been inactive for thousands of years and shows no sign of ever erupting again.

What is a volcano?

It is a mountain, in the middle of which there is a deep vent. At the bottom, there is a pool of molten rocks called magma. The magma mixes with gases and slowly build up the amount of pressure. The temperature rises, melting more rocks, increasing the pressure the pressure of both gases and magma.

At a certain level of pressure, the top of the vent which is partly covered by hardened lava and even plants, depending how long ago the volcano erupted, the explosion might be violent or more quiet. Then the magma is released out of the vent, flowing out of the volcano. It is now called lava.

Some volcanoes are now extinct which means that there was no volcanic activity recorded for centuries. Some volcanoes are dormant which means that they have not erupted in a long time. Other volcanoes are active but the timing between the eruptions vary greatly.

Volcano eruptions have been known to destroy forests and villages but also to have affected or even caused other natural disasters such as: mudflows, flashfloods, earthquakes, rockfalls and even tsunamis.

The pulverized rocks become ashes which can be acidic, smelly, glassy, harsh and gritty. It is said that the ashes of volcano eruptions can remain partially into the atmosphere for up to two years, affecting the weather conditions.
