Mayon
Geology
In August 2021, soils from Mayon have been found containing bacterial species with potential antibiotic and anti-cancer properties.
1881–1882 eruption
At the date of my visit, the volcano had poured out, for five months continuously, a stream of lava on the Legaspi side from the very summit. The viscid mass bubbled quietly but grandly, and overran the border of the crater, descending several hundred feet in a glowing wave, like red-hot iron. Gradually, fading as the upper surface cooled, it changed to a thousand sparkling rills among the crevices, and, as it passed beyond the line of complete vision behind the woods near the base, the fires twinkled like stars or the scintillations of a dying conflagration. More than half of the mountain height was thus illuminated.
2000 eruptions
Mayon had experienced continuous emissions since 1999 and followed by a series of eruptions in the next two consecutive years.
