Hibok-Hibok

Definition

Hibok-Hibok (Mount Hibok-Hibok) is the only historically active volcano on Camiguin island province, a 1,332-meter stratovolcano on its northern coast. Its 1951 eruption, one of the deadliest volcanic events in twentieth-century Philippines, prompted landmark developments in volcano monitoring and evacuation planning.

Also Known As

Mount Hibok-Hibok; Catarman volcano (historical usage); Camiguin volcano.

Examples and Analogies

The 1951 Hibok-Hibok eruption is often compared to Mount Pelée 1902 because both produced fast-moving pyroclastic flows—searing avalanches of gas and ash—that swept low-lying settlements with little warning. Its dome-building behavior resembles that of Kanlaon and other young Philippine volcanic centers.

Usage Scenarios

The volcano’s slopes host hot springs (notably Ardent), waterfalls, and the popular Hibok-Hibok trail to the summit crater, typically climbed overnight from Mambajao. Geothermal and scientific interest continues, and PHIVOLCS maintains a monitoring station on the island for seismic and gas surveillance.

Strategies

Local government drills rehearse sectoral evacuation toward designated safe zones away from radial valleys. Tourism is managed with accredited guides, fixed climbing seasons, and crater-area closures whenever alert levels rise.

Security and Safety Measures

Hiking is suspended at Alert Level 1 and above, and permanent danger-zone maps guide land-use planning around the volcano. The island’s disaster risk reduction office coordinates with PHIVOLCS for real-time advisories.

Historical Context

Camiguin’s recorded eruptions include activity in 1827 and the 1871–1875 episode that birthed the submarine vent Vulcan, which grew into a new lava dome and buried the old Catarman town. After relative quiet, Hibok-Hibok erupted from 1948 to 1953; the December 1951 pyroclastic flows killed around 500 people and destroyed Tuwa and other barrios, spurring the creation of the Commission on Volcanology, predecessor of PHIVOLCS.

Challenges and Controversies

Settlement creep into lahar-prone valleys and hot-spring development near active vents raise land-use concerns. Balancing the island’s tourism economy with strict alert-level closures is a recurring local debate.
