Land/River/Rainfall Observation System
NEC's Land/River/Rainfall Observation System collects necessary information and data by means of various sensors placed at disaster-prone areas.
Ocean Bottom Observation System
NEC's Ocean Bottom Observation System obtains earthquake and tsunami data by means of seismometers and tsunami sensors placed at the ocean bottom, and send the real-time data to an on-shore station through the submarine cable. The transmitted data then are further distributed to government agencies and research institutions via terrestrial links, thus enabling early warning to the public with higher accuracy.
