Based on the periodicity of eruptions, volcanoes are classified into

Active volcanoes are those which constantly eject volcanic lava, gases and fragmented materials Eg: Mount St. Helens in the United States.
- Dormant Volcano:
- Volcanoes that do not show any sign of volcanic activity for a long period of time are known as dormant volcanoes.
- Sometimes there may be a sudden explosion which may cause unimaginable loss to life and property.
