They can erupt anytime, when magma rises from the mantle and spews out of the volcano.
What causes a volcano to erupt? Depending on the type and duration of the eruption lava and or tephra can pile up to make a volcano. What happens when volcanoes erupt? When it reaches the top, it explodes from the cone of the volcano.

What causes a volcano to erupt and how do scientists predict eruptions? Bob Abram, MOLTEN ROCK, or magma, and gasses spew from the mouth of a volcano in more
Homemade volcanoes are made from vinegar and baking soda. It "erupts" because as the vinegar and baking soda come into contact with each other, a chemical reaction takes place which causes it to fizz.
It can be called an active, dormant or extinct volcano. An active volcano erupts regularly and frequently, however, it might not erupt at some times. A dormant volcano rarely erupts. Therefore, it does not erupt for most of the time. An extinct volcano does not erupt anymore.
An extinct volcano is one that will never erupt again.

What usually causes a volcano to erupt like Eyjafjallajokull is a slight disturbance in the ground.
It cause by the volcano erupt
Godzilla swims around and causes it to erupt.
Very well done young man

It depends, a volcano can erupt once and never erupt again. Or, a volcano can erupt multiple times a day.
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.

In order for a volcano to erupt, magma must move toward the surface. This causes rock to shift and break underground, generating earthquakes.
Yes. If it doesn't erupt and never has erupted then it is not a volcano.
