September 6, 1995 Eruption of Melebingoy

Nearly 100 persons killed by flood from breach of caldera wall either due to natural causes or manmade blasting; 300 homes were destroyed and 50,000 persons displaced. No eruption. (reference #9675)

Crater lake overflow causes flooding; no volcanic activity. The overflow of Maughan Lake, the crater lake at Parker volcano, followed heavy rains associated with a passing typhoon and caused flash flooding in NW-flank communities on 6 September. A team from the Philippine Institute of Volcanology and Seismology (PHIVOLCS) was dispatched to determine whether the overflow was caused by volcanic activity. Although no volcanic alert was declared, PHIVOLCS recommended that the crater area should be considered off-limits because of instability of the crater walls. Fieldwork on 8-9 September revealed that the flood was channel-confined along the NW-flank Alah River, which drains the crater lake, from 1,000 m down to 540 m elevation (Barangay New Dumangas, T'boli, South Cotabato Province). Below this point it was transformed into a sheetwash. The floods killed more than 60 people, destroyed 300 homes and nine bridges, and displaced 50,000. (reference #2432)
