Indonesia's Cable Based Tsunameter (CBT) System as an Earthquake Disaster Mitigation System in East Nusa Tenggara

Indonesia is located between the Ring of Fire, stretching from Nusa Tenggara, Bali, Java, Sumatra to the Himalayas, Mediterranean, and then culminates in the Atlantic Ocean. Therefore, Indonesia has many active volcanoes that cause earthquakes, such as recently in West Sumatra, Southern Java, and around East Nusa Tenggara (NTT). Disaster mitigation, especially seabed monitoring, is needed as one of the early detection efforts of a seabed earthquake that will potentially become a tsunami disaster. The National Research and Innovation Agency (BRIN) has developed a marine disaster detection system since 2004 called Indonesia Tsunami Early Warning System (InaTEWS). BRIN has placed several seabed earthquake detectors that spread throughout Indonesian waters from Sumatra to Sorong Papua. The seabed monitoring system described in this paper is the Cable Based Tsunameter (CBT) using a Solar Power Plant developed by BRIN and it will start operating by the end of 2021. The Paper describes the devices used for the CBT system, which will be installed in a location at NTT, and the capacity of the Solar Power Plant is 7kWp to energize the electricity of the CBT system.
