 Taal Volcano Observatory  Instrument and computer set-up of seismic network


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. At present, the observatory serves as the central monitoring station for Taal Volcano.
