DEVELOPMENT OF TSUNAMI EARLY WARNING APPLICATION FOUR MINUTES AFTER AN EARTHQUAKE.

Effective early warning at local to regional distances is maximum 10 minutes after the OT. The shorter the tsunami early warning time that is announced, of course, the more time the community will have to prepare for mitigating the disaster. The purpose of this study is to develop a tsunami application and show the current real-time data available in most tsunami hazard areas in Indonesia - in particular, earthquake location, magnitude and tsunami discriminant Td, T50Ex, T0, Td x T50, and Td x T0 can be determined about four minutes after the earthquake occurs. This process will be implemented and continues in real-time in earthquake monitoring and tsunami early warning installed by the Meteorology Climatology and Geophysics Council. The availability of this rapid tsunami application (about 4 minutes after the OT) can help in tsunami early warning that is faster and more reliable for short distances to areas that have the potential of having the a tsunami impact. The purpose of this study is to produce a tsunami early warning application 4 minutes after the earthquake. The research method used in this study is the ADDIE development method (Analysis, Design, Development, Implementation and Evaluation). In the first year, the focus of the development of rapid tsunami early warning applications was about 4 minutes after the OT. Our previous research results have supported a lot of development this application and make it easier for us to complete the prototype target, it has been obtained the results of the tsunami application prototype 4 minutes after the OT which is currently being tested in real time at the Meteorology Climatology and Geophysics Council Research and Development Center in Jakarta, Indonesia.
