Abstract

DONET (Dense Ocean-floor Observatory Network for Earthquakes and Tsunamis) is a submarine cabled real-time seafloor surveillance infrastructure for earthquake activity at assumed focus region of mega-thrust earthquake around Japan. The original system DONET1 was constructed in To-Nankai earthquake focus region and twenty seafloor observatories are working in operation beginning in 2011 to contribute the earthquake and tsunami early warning program in Japan. Development of second seafloor network DONET2 was planned in 2010 to target Nankai earthquake focus region. This paper describes a decision making approach of DONET2 observation site arrangement based on the knowledge of DONET1 development and construction.
