Submarine Cable Data Center

Realtime Data from the Deep Sea Floor Observatory
(off Kushiro-tokachi, off Muroto, off Hatsushima)

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. 
This site is presented with the objective of widely providing observation data of the foregoing systems.
