There are both primary and secondary hazards which can be caused by volcanic eruptions. The primary hazards include pyroclastic flows, air-fall tephra, lava flows and volcanic gases. The secondary hazards include ground deformation, lahars (mudflows), landslides and possibly tsunamis in ocean floor volcanic eruptions.
List of Volcanic Hazards
- Pyroclastic Density Currents (pyroclastic flows and surges)
- Lahars.
- Structural Collapse: Debris flow-Avalanches.
- Dome Collapse and the formation of pyroclastic flows and surges.
- Lava flows.
- Tephra fall and ballistic projectiles.
- Volcanic gas.
- Tsunamis.
