Volcanoes erupt when there is an earthquake or when there is too much pressure inside it.
It is not true that a dormant volcano is erupting. If it's erupting, it's by definition not dormant. It has pretty much always been, and will pretty much always be, true that a dormant volcano may erupt in the near future.
Pretty much because they both have swag and erupt
too much air pressure
Usually the magma clogs causing major pressure causing the volcano to explode violently or some times movement in the earths crust

A volcano can erupt many times. If the pressure from below builds up too much, the volcano will erupt, throwing out very hot gases and lava, until the pressure has been released.
Volcanoes underwater erupt in much the same way as those on dry land. They erupt when pressure builds up. The difference between these two types of volcanoes is that the lava produced in an underwater volcano cools dramatically faster than the lava on land.
It depends on how much silica is in the magma. If there is low-silica in the magma then the volcano will erupt quietly. If there is high-silica in the magma then the volcano will erupt explosively.

The pressure and heat in the volcano. When to much pressure builds it makes a eruption.
a lot
the heat of the volcano made the ash rise eventually the pressure was 2 much and it erupted
You're probably thinking of the second, much larger volcano in Iceland that began showing signs that it may be about to erupt after the start of the Eyjafjallajökull eruption. That volcano is named Katla.
Earths energy is released when there is too much heat inside of Earth and volcano's erupt.
too much air pressure
