Indian Ocean Wave Exercise 2018 (IOWave18) began on September 4, 2018, in the Indian Ocean. India along with 23 other nations is participating in this major Indian ocean-wide tsunami mock drill which involves evacuation of thousands of people from coastal areas in over half a dozen coastal states.
1. Exercise IOWave18 will simulate Indian Ocean countries being put in a tsunami warning situation and require the respective National Tsunami Warning Centres and the Disaster Management Offices in each country to implement their Standard Operating Procedures.
2. The IOTWMS Tsunami Service Providers (TSP) of Australia, India and Indonesia will provide exercise bulletins and detailed tsunami threat advice on their password-protected websites.
3. IOWave18 will also provide an opportunity for Member States to test the indicators of Indian Ocean Tsunami Ready (IOTR) programme in pilot communities. IOTR is a community performance-based programme that facilitates a structural and systematic approach in building tsunami preparedness.
4. Exercise IOWave18 will comprise two scenarios on successive days: one in the northwestern Indian Ocean off the coast of Iran, and the other in the eastern Indian Ocean off the west coast of northern Sumatra.
5. Both scenarios will generate simulated tsunami waves travelling across the Indian Ocean basin.
6. The first scenario will simulate a magnitude 9.0 earthquake off the coast of Iran and the second scenario will simulate a magnitude 9.3 earthquake off the west coast of Northern Sumatra.
