video that show formation of pyrocrust

The term "pyrocrust" is not a standard geological term. However, it likely refers to a layer or crust formed from pyroclastic material, which is fragmented volcanic rock ejected during an eruption. This material can include ash, lapilli, volcanic bombs, and blocks. When these materials are deposited, they can form various types of volcanic deposits that might be informally referred to as a "pyrocrust" depending on their consolidation and appearance. To find videos showing the formation of such deposits, you could search for: Pyroclastic flow deposition: These videos show the movement of hot gas and volcanic debris, and how they deposit material that can later solidify into rock like ignimbrite. Volcanic ashfall: Videos demonstrating ash plumes and the subsequent settling of ash layers. Tephra deposition: Similar to ashfall, but encompassing a broader range of fragment sizes. Formation of ignimbrite: This is a rock formed from solidified pyroclastic flow deposits. Formation of tuff: This is a rock formed from compacted and lithified volcanic ash and other pyroclastic fragments. You can find many such videos on platforms like YouTube by using these search terms.
