Vent position
Where material emerges can influence an early surface route. It is one control among many rather than a complete explanation.
Use the 2018 scene to ask why lava can be visible, why movement may favor one flank, and why a visual route is not a real-time flow prediction.

Gravity and local surface form influence movement. A terrain model is useful for orientation but is not a numerical flow simulation.
Discharge, eruptive behavior, material properties, and changing vents affect real events. They are not calculated by this illustration.
The glowing south-flank route is a teaching layer based on the experience’s historical context and terrain. It is designed to prompt process questions, not to estimate runout, volume, timing, probability, or a future route.
For current Mayon activity, official alerts, exclusion zones, or emergency guidance, consult PHIVOLCS and local authorities.
Use the Smithsonian Global Volcanism Program Mayon record for eruption-history context and the methods page for the simulator’s explicit limits.
