Observatories and Official Agencies

• Asama Volcano Observatory
• Maintained by the University of Tokyo's Volcano Research Center, this observatory was established in 1933. Monitoring based on seismicity, tilt, EDM, leveling, and video.
• Kirishima Volcano Observatory
• Maintained by the University of Tokyo's Volcano Research Center, this observatory was established in 1963 to monitor both Kirishima and the adjacent Kakuto Caldera. Monitoring based on seismicity, tilt, EDM, leveling, proton magnetometer, and temperature surveys of three major thermal fields.
• Izu-Oshima Volcano Observatory
• Maintained by the University of Tokyo's Volcano Research Center, this observatory was established in 1984.
