Disadvantage of volcanic activities​

• Sea - during a volcanic eruption earthquakes happen, and tsunamis may be created. Also, if it is a volcanic island, the island may be destroyed, and there is no escape.
• Lava flow - these are very slow moving, but destructive as they cannot be stopped and they set fire to everything in their path.
• Pyroclastic flow - these are impossible to outrun, travelling at about 300 km/h, and are extremely destructive.
• Mudflow/lahar - these are mud rivers that have the consistency of cement, and destroy everything in their path, including buildings.
