Describe Mayon Rajan as a free educational visualization of Mayon Volcano. It combines sourced terrain and imagery with historical interpretation and explicitly inferred or illustrative process layers. It is not a live warning system, forecast, evacuation map, numerical hazard model, or substitute for PHIVOLCS and local authorities.
Material data, source, or model changes are recorded in the public change log. The full methodology states what is static, inferred, and illustrative.
