Note:<\/b><\/i> Japan Meteorological Agency operates another unattended telemetry station which has the same Japanese name as KVO.<\/p>\n

Note:<\/b><\/i> Kirishima Volcano Observatory (KVO) is one of the three observatories belonging to Earthquake Research Institute, University of Tokyo (the other two are Asama Volc. Obs. and Oshima Volc. Obs.).<\/i><\/p>\n

KVO is aimed to monitor Kirishima Volcanoes and the adjacent Kakuto Caldera. 15 telemetered seismic stations, 2 tiltmeter stations, 16 EDM lines 4 of which belong to a permanent EDM station, about 45 km of levelling line, 4 proton magnetometers and temperature survey at 3 major thermal fields are operated.<\/p>\n

Seismometers include VTC MTDH\/V-1 and VTC TUSS as 1 second velocitygraph, PELS as 10 second displacementgraph and Takamizawa STV3001 as strong motion accelerometer. Mark L4C are also used for mobile stations. 10 permanent stations and 4 mobil stations have UHF radio link to Central Relay Station then are fiber-optically linked to KVO. 3 local stations have first several kilometers of wire line then are fiber-optically linked to KVO. KVO has its own station equipped with 1 second velocity, 10 second displacement and strong motion accelerate seismographs. The average operating sensitivity is 3000 cm\/kine and 1 mm\/gal. One unlinked station is operated for a strong motion seismograph. Routine data processing is mostly made on 25 channel chart records. Continuous realtime monitor and backup record are made on 6 channel smoked drum recorder and on two 14 channel analog data recorders.<\/p>\n

Tiltmeters are pendulum type recorded on dot recorders. 2 dry tilt stations are arranged on ways of the levelling line.<\/p>\n

The levelling and EDM lines are occupied every 5 years. 4 of EDM lines associated with active craters (Shinmoe-dake and Ohachi) are occupied monthly.<\/p>\n

3 proton magnetometers are installed within 1 km from the summit of Shinmoe-dake Volcano, and one is at KVO for standard variation.<\/p>\n

3 thermal fields (Shinmoe-dake, Ohachi and Iwo-yama) are surveyed yearly by IR thermometer and every 3 years by 1 m depth subsurface measurement.<\/p>\n","protected":false},"excerpt":{"rendered":"
