 🌋Then and Now - Herculaneum boat sheds.

Why ? ❓

- Effects of bradyseism and of course the pyroclastic deposits. Actually some parts of ancient herculaneum are actually 4m below sea level due to bradyseism!

- Herculaneum was buried by superheated pyroclastic flows, preserving organic materials through carbonization (like wood and food) under 20 meters of volcanic material, unlike Pompeii's ash burial. Over centuries, bradyseism (ground subsidence) caused parts of ancient Herculaneum, especially its original coastline, to sink significantly, with some areas now 4 meters below current sea level. This combination led to its deep burial and unique preservation, despite coastal sections now being submerged.
