The Philippine Institute of Volcanology and Seismology (Phivolcs) rejected the BFAR's finding. Buhi has a population of 67,762 people and comprises 13,238 households.
On September 22, 2007, a fish kill in Camarines Sur's Lake Buhi threatened the livelihood of local fishermen. The Bureau of Fisheries and Aquatic Resources (BFAR) stated that it resulted from sulfur dioxide from Iriga City, since the rains by the southwest monsoon loosened the sulfur dioxide from nearby volcanoes.
