🌋 Pyroclastic Flow Dynamics

Trigger a simulated eruption column collapse on a 3D volcano and watch a pyroclastic flow of hot gas and ash race down the slope, with adjustable temperature and density controlling speed and reach.

Trigger a simulated eruption column collapse on a 3D volcano and watch the resulting pyroclastic flow of hot gas and ash surge down the slope, with temperature and density controlling how fast and how far it travels.

🔬 What It Demonstrates

An unstable eruption column falls back under gravity and spreads as a radial density current. Hotter, gas-rich mixtures stay buoyant and travel farther as fast dilute surges; denser, ash-rich mixtures stall sooner as slow block-and-ash flows.

🎮 How to Use

Set magma temperature, flow density and column height, then press Trigger collapse. Watch the estimated runout and live flow-front stats update as the current races outward and finally settles into an ash deposit.

💡 Did You Know?

The 1902 eruption of Mount Pelée produced a pyroclastic flow that destroyed the city of Saint-Pierre in under two minutes, killing nearly 30,000 people — one of the deadliest volcanic disasters in recorded history.

⚙ Under the hood

Interactive 3D volcano where triggering a simulated column collapse shows a pyroclastic flow of hot gas and ash racing down the slope, with adjustable temperature and density affecting speed and reach.
