When a volcano has an intense, explosive eruption, it can fling rocks at a velocity of up to 670 miles per hour. Generally speaking, when a volcano starts to erupt, the eruption continues for around 10 years. Some eruptions have been known to last for hundreds of years.

    What is a dome volcano?

    A:

    A dome volcano, or a lava dome, occurs when a dome forms over the vent of a volcano because the eruption is too slow. Once the lava cools down, it forms a dome. The domes are typically fairly steep and filled with silica-rich lava, which is prone to explosions.

  • Q:

    What do you call a volcano that no longer erupts?

    A:

    A volcano that no longer erupts but has the potential to erupt again is called a dormant volcano. If the volcano has not erupted for at least 10,000 years and is unlikely to erupt again in the foreseeable future, it is called an extinct volcano. These types of volcanoes are different from an active or erupting volcano.
