Indonesia Tsunami Early Warning System (InaTEWS)
by Agency for Meteorology, Climatology, and Geophysics of the Republic of Indonesia (BMKG) (Government)
Indonesia Tsunami Early Warning System (InaTEWS) is an operational activity carried out by Agency for Meteorology, Climatology and Geophysics as a part of governmental duty which shall provide meteorology, climatology, and geophysics service including public information, early warning, and specific information. BMKG is a tsunami service provider under UNESCO/IOC that responsible providing tsunami threat notification to the Indian Ocean member states.
Objectives of InaTEWS includes:
1. Delivers early warning to coastal communities when earthquake occurs and its potential in forming tsunami in the area.
2. Improves cooperation between institution and government on development of science and technology in order to enhance accuracy of tsunami early warning system as a consequences of wide tsunami impacts area.
3. Develops TEWS technology using equipment and infrastructure such as weather station or ocean wave radar on the water which provides ocean temperature, wind and ocean wave data to be used as weather forecast to support information on climate change and its impact.

Implementation Methodologies
a. Operational:
Monitoring, analysis, dissemination of tsunami warning (joint cooperation between BMKG, BIG, and BPPT)

b. Mitigation and Emergency Response:
