Can an earthquake happen during a volcano?

Something cannot happen during a volcano, as a volcano is a thing, not an event. However, earthquakes often do happen during volcanic eruptions. This is because of the often large amounts of magma moving underground, breaking rock around it.


Do volcanic eruptions cause earthquakes?

Not usually. Although earthquakes often occur before a volcanic eruption, they are not the cause. The earthquakes are the result of magma (molten rock) moving underground leading up to an eruption. A few volcanic eruptions are thought to have been triggered or initiated by earthquakes, but this is not the typical case.


What is the cause of earthquakes in volcanic regions?

Earthquakes are like a rubber band. They both have limits. If you strech a rubber band the farthest it can, it will eventually meet it's elastic limit or the point where it can strech its farthest. If you go any farther than its elastic limit the rubber band will break. This is an example of how earthquakes are formed.I'm not sure if a volcano can cause earthquake or an earthquake can cause an volcanic eruption or both. But earthquakes can cause volcanoes to erupt. There are many kinds of earthquakes some are big and destructive but most of them are small that we can't even feel. Small earthquakes are important now and then because if they don't happen often the stress and force build up and create a big earthquake. One cause of earthquake causes in volcanic regions can probably be the shaking of an earthquake can cause an eruption. Or the shaking ofa volcano can cause an earthquake.
