Abstract

A new cabled observatory Tokai SCANNER (Tokai Submarine Cabled Network Observatory for Nowcast of Earthquake Recurrences) was completed in April 2007. The system is located off the coast of Toyohashi-city where huge earthquakes are anticipated and continuous long-term monitoring is needed to promote seismic study. A new junction box which is equipped with underwater mateable connectors was installed at the end of the cable. The cable itself will be also applied to electromagnetically study for the inner structure of crust. This paper describes the outline of the Tokai SCANNER and initial evaluation results of the component units.
