Philippine Institute of Volcanology and Seismology


Hibok-Hibok Volcano Observatory, Quiboro

Instrument set-up at HVO

Prior to the eruption of Hibok-Hibok Volcano in September 1948 a seismic monitoring station was already established in Mambajao, Camiguin. The seismic station utilized a 2-component low magnification Vincentti seismograph, which was later replaced by a 2-component Loucks-Omori seismograph with a maximum magnification of 500 dB. The seismic station was turned over to the Commission on Volcanology after its creation in June 1952. In 1967, another station, located half a kilometer away was established by COMVOL but was decommissioned when Hibok-Hibok Volcano Observatory began operating.

Hibok-Hibok Volcano Observatory (HVO), located at the northeast slope of the volcano in Quiboro, Mambajao was constructed in 1975. Monitoring devices in the observatory consist of a short period seismograph, a water tube tiltmeter, rain gauges, a short wave radio transceiver and a service jeep.  At present, the observatory serves as the Central receiving and processing center of data coming in from different seismic remote stations around the volcano.
