Big Island Lava Flow Simulator (Educational)

Scenario & Controls

Past eruption scenario

Run speed 1.00×

Effusion / supply (lava volume rate) 60

Viscosity (stickiness) 25

Cooling / crusting rate 35

Topography strength (slope influence) 70

Flow thickness (relative) 50

How speed is modeled (simplified): lava-front speed increases with slope + supply + thickness, and decreases with viscosity + cooling/crusting. This is a conceptual simulator for students to experiment with cause/effect.

Controls: Space play/pause • R reset • click map (paused) to move vent

The island outline and vents are stylized to resemble Hawaiʻi Island. This does not reproduce exact historic flow boundaries.
