Final answer:
There are several types of volcanic hazards, including volcanic ash fall, pyroclastic flows, lahars, volcanic gases, and volcanic landslides.
Step-by-step explanation:
The hazards associated with volcanism can be grouped into several types, including volcanic ash fall, pyroclastic flows, lahars, volcanic gases, and volcanic landslides.
Volcanic ash fall occurs when volcanic ash is ejected from the volcano and falls to the ground, covering the surrounding area. Pyroclastic flows are fast-moving streams of hot gas, ash, and rocks that flow down the sides of the volcano.
Lahars are mudflows or debris flows that result from the mixing of water and volcanic ash or debris. Volcanic gases, such as sulfur dioxide, carbon dioxide, and hydrogen sulfide, can be released during volcanic eruptions and pose a health risk to humans.
Volcanic landslides, also known as volcanic landslips or debris avalanches, occur when volcanic material collapses and slides down the volcano's slopes.
