HIBOK-HIBOK VOLCANO OBSERVATORYline

HVOAug2018 6

 Hibok-Hibok Volcano Observatory (HVO), Mambajao, Camiguin

 

 

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 instruments in the observatory consist of a short period seismographs, a water tube tiltmeter, rain gauges, a short wave radio transceiver.

Monitoring works at Kanlaon Volcano began with the establishment of temporary volcano stations at Canlaon City (based in the house of then Mayor Bautista) for about 3 years, then at Valencia, Dumaguete until the 1969 eruption. During the 1969 eruption, the Valencia station was moved back to Kanlaon City. In 1982, a permanent volcano observatory was constructed in Barangay Pula, Canlaon City to continuously monitor the activity of Kanlaon Volcano. A second observatory was constructed in early 2003 in the premises of the La Carlota City College, Cubay Campus, La Carlota City, Negros Occidental.

MAYON VOLCANO OBSERVATORYline

MVOAug2018 8

Mayon Volcano Observatory (MVO), Lignon Hill, Legazpi City, Albay 

 

Legaspi Volcano Station, the first volcano monitoring station at Mayon Volcano was established in 1955 and housed at the Civil Aeronotics building located near the Legaspi City airport. The second volcano station was established in 1966 in Barrio Sta. Misericordia, Sto. Domingo. It was first equipped with a 3-component Akashi seismograph and a short wave radio transceiver. After a few months, the E-W component of the Akashi seismograph was replaced with an E-W component of a high magnification Hosaka seismograph. This station was transferred to Aquinas University in 1973 upon the request of the University Administration. After almost two years, the station was transferred to the Sta. Misericordia Health Center then moved to the newly constructed COMVOL Sta. Misericordia station on 16 October 1976. The Sta. Misericordia station is located at the northeast basal slope of the volcano and less than a kilometer away from the Health Center.

The seismograph installed at the Provincial Resthouse, located at elevation 760 m above sea level at the NNW slope of the volcano had been gathering more reliable monitoring data than the other two stations. For this reason, COMVOL constructed Mayon Resthouse Observatory (MRHO) in 1969, located a few hundred meters upslope the Provincial Resthouse. The MRHO was equipped with a 3-component Hosaka seismograph, a watertube tiltmeter and a short wave radio transceiver. In late 1971, the Legaspi Volcano station was de-commissioned.

A third observatory, the Lignon Hill Observatory was constructed in 1989. The observatory is situated along the flank of a prehistoric cinder cone in the southeast slope of Mayon.

PINATUBO VOLCANO OBSERVATORYline

 Pinatubo Volcano Observatory (PVO), Pampanga State University, Magalang, Pampanga

 

 

The phreatic explosions that suddenly occurred at Mt. Pinatubo’s crater on 02 April 1991 obliged PHIVOLCS to set up a temporary monitoring station at Sitio Yamut, Botolan, Zambales (west side of Pinatubo) on 05 April 1991. The temporary station closely monitored the volcano’s growing unrest. In May, the Yamut station was transferred to Burgos then to Poonbato. The temporary station was responsible for issuing daily updates and hazard warnings on the volcano’s growing unrest. As the volcano’s unrest persistently increased, Pinatubo Volcano Observatory (PVO) was established inside the Clark Airbase Compound, Pampanga with assistance from the United States Geological Survey. The first state-of-the-art seismic telemetry and ground deformation networks were set up with Pinatubo Volcano Observatory as its central station. The seismic telemetry network was linked to computers for effective and rapid location of earthquakes. Other significant monitoring activities included gas studies using Correlation Spectrometer and periodic aerial surveys. However, due to the difficulty and harsh environmental conditions in maintaining remote monitoring stations, the telemetry system was pulled out after Pinatubo Volcano’s activity returned to quiet and normal conditions.

 TAAL VOLCANO OBSERVATORYline

TVOAug2018 2  

Taal Volcano Observatory at Buco, Talisay, Batangas

 

 

Surveillance at Taal Volcano began in December 1952. The first volcanological station at Taal Volcano was established in Barrio Alas-as, along the western shore of Volcano Island. It was initially equipped with a three component, low sensitivity Akashi seismograph; a water tube tiltmeter; thermometers and short-wave radio transmitters.

 

The Alas-as station in Volcano Island was destroyed during the 28 September 1965 eruption. The volcano station was sand blasted and all monitoring equipment were destroyed. In 1966, Taal Volcano’s Pira-piraso station was established and equipped with a 3-component Akashi seismograph and one component Whitmore seismograph and a watertube tiltmeter. Later, a 3-component Hosaka seismograph was installed to replace the Whitmore seismograph. In 1968, the Akashi seismograph was replaced by a short period Inshimoto seismograph. In 1970, a 3-component Hosaka seismograph and a Sony tape with Watanabe recorder replaced both the Akashi and Inshimoto seismographs. Buco Observatory, located at the northern shore of Taal Lake, Buco, Talisay was constructed in 1969-1970 under the supervision of the Department of Public Works. The observatory was turned over to COMVOL when its construction was nearly completed. The observatory was initially equipped with a 3-component strong motion Inshimoto seismograph, a 3-component Hosaka seismograph and a short wave radio transceiver, a motorized banca and a speedboat.

 MATUTUM/PARKER VOLCANO OBSERVATORY

 

Monitoring of Matutum and Parker volcanoes started in 2003 where two (2) seismic stations were installed at the two volcanoes using short period seismometers. The Data Receiving Center for the two stations was setup at the existing PHIVOLCS' Gensan Seismic Observatory building inside the Mindanao State University Campus, General Santos City.
