| Sept. 1 occurred first crateral outburst from suphur pits in 1897-1902 and activity continued punctuated by eruptive phases; Phase 2 (paroxysmal activity): explosions, or steam blasts, concomitant with the emission of heavy clouds of steam, ashes, and other fragmentary volcanic materials, with a strong possibility of the development of “nuees ardentes d’explosion vulcanienne” | Pelean | Pelean,
Steam blasts that produced ‘nuees ardentes d' explosion vulcaniene’, black lava flows
| Mambajao town, NE sector of the volcano, arable land overrun by lava flows; about 500 casualties; most violent phase occurred in December 4, 1951; damaged properties and structures worth thousands of pesos | (Alcaraz,1952) |
