Philippines Mayon VOLCANO alert – Public EVACUATION from risk of ‘magmatic explosions’.
The Philippine Institute of Volcanology and Seismology (PHIVOLCS) raised the warning to level two, meaning the current activity displayed by the Mayon Volcano is "probably of magmatic origin, which could lead to more phreatic eruptions or eventually to hazardous magmatic eruptions."
The institute added: "The public is strongly advised to be vigilant and desist from entering the six kilometre (3.7mile) radius Permanent Danger Zone to minimise risks from sudden explosions, rockfall and landslides.”
A phreatic eruption, also known as a phreatic explosion, occurs when magma heats ground or surface water, resulting in steam rising into the sky.
Two villages near the volcano were evacuated as well as a tourist attraction in central Albay province due to its cone shape that could see ash and rainfall accumulate.
