There are several types of volcanic flows, including:
Lava flows: These are streams of molten rock that flow down the sides of a volcano during an eruption.
Pyroclastic flows: These are fast-moving currents of hot gas, ash, and rock that flow down the sides of a volcano at high speeds.
Lahars: These are volcanic mudflows that can occur when heavy rain mixes with ash and debris on the slopes of a volcano.
Pillow lavas: These form when lava erupts underwater and cools rapidly, creating pillow-shaped structures.
Lava domes: These are mounds of thick, slow-moving lava that can accumulate at the top of a volcano during an eruption.
