WHAT CAUSES A VOLCANIC ERUPTION?
A volcanic eruption is a violent explosion in the land surface made of material from the insides of the earth. They don´t follow any periodicity law so no method of predicting this events has been made, even though sometimes they are preceded by quakes or fumaroles (A mixture of gases and vaporsthat surge from the cracks on the volcano´s exterior). The eruptions are caused by the rising of the magma´s temperatureunder the Earth´s mantle. This causes the surgethat expels the boiling lava that was trapped in the magma.
