A pyroclastic flow is primarily composed of the following materials:
1. **Dust**: Fine volcanic ash and fragments.
2. **Rock**: Larger volcanic rock fragments and pumice.
3. **Lava**: Molten rock that can be part of the flow.
4. **Gas**: Hot gases released during the explosive eruption.
All of these components combine to create a fast-moving current of hot gas and volcanic matter that flows down the slopes of a volcano during an explosive eruption.
