JAMSTEC Realtime Data from the Deep Sea Floor Observatory

The Japan Agency for Marine-Earth Science and Technology (JAMSTEC) established the first Long-Term Deep Sea Floor Observatory off Muroto Cape in fiscal year 1996, and the Long-Term Deep Sea Floor Observatory off Kushiro and Tokachi in the Kuril Trench in 1999 as part of a plan to build basic earthquake observation networks in Japan. JAMSTEC now is planning the construction of additional systems. Observational data of the foregoing systems are available now.
