Slide10: ESTIMATION OF TSUNAMI HEIGHTS DEPENDING ON THE
SPEED OF PROPAGATION OF THE WAVE FOR INCOMING TSUNAMI WAVES
FOR THE DELTAIC COAST ESTIMATION OF TSUNAMI HEIGHT FOR MYANMAR COASTAL AREAS
BY USING THE STORM SURGE HEIGHT PREDICTION MODEL FOR AN APPROACHING TSUNAMI WAVE WITH A SPEED OF 500 Km/Hr
COULD GENERATE A TSUNAMI WAVE OF HEIGHT 29 METRES FOR THE DELTAIC AREA The tsunami height of about 3 metres was observed in Myanmar coast during
the Indian Ocean Tsunami of December 2004. The corresponding speed of propagation
of the tsunami wave appraching Myanmar coast was calculated as 160 km/hr. 10 ASSESSMENT
Slide11: During the last episode of Indian Ocean Tsunami of December 2004, the arrival time of tsunami wave towards Myanmar was about 3 hours. Since the epicentre is at a distance of about 1000 km away, the average speed of approaching tsunami waves towards Myanmar coast is 330 km/hr. By using the storm surge model, the calculated speed of propagation towards the coast is 160 km/hr.
The reduction in tsunami wave speed on entering the coastal shelf could be regarded as
the combined effect of shallow water of Myanmar and the morphology of the Andaman sea. Whatever. The fact is that there was a minimal damage in Myanmar
due to the 2004 Indian Ocean tsunami comparing to our neighbouring countries. 11 ASSESSMENT

were limited in the north up to only Coco Island. 21
Indian Ocean: Historical Tsunamis:
There were eight incidents of maritime earthquakes in the Indian Ocean
in record. The years were 1524, 1762, 1819, 1847, 1881, 1941, 1945 and 1977. Due to lack of good records on Tsunami events and tolls of death
in the Indian Ocean, no Tsunami Early Warning System was established
till the deadliest Tsunami of the history occurred in December, 2004.

Slide63: Aim: Set up an operational 24-hour Tsunami Warning and Mitigation System hosted within the Ministry of Transport
Support Pledged by: Department of Meteorology and Hydrology will avail part of her current facilities and staff for the Project.
Support sought for: Upgrading and expansion of the current communication network and sea level observing network, Development of a seismic network and Capacity building. Project Proposal (Objectives) 57 Myanmar Requirement
Slide64: Three-year programme:
To develop a system that will be based on and end-to-end principle – from data collection to the provision of services and issuing of warnings.
Based on existing infrastructure and resources to develop
Five major components:
- Monitoring network – seismic and sea level
- Data transmission and receiving system for evaluation and sharing
- Data processing system for acquiring and evaluation
- Dissemination of warnings to target communities
- Training of trainers to develop tsunami awareness in the target areas
The system will be integrated into the existing national disaster management system, and will also contribute to the IOTWS. Close links with International organizations such as IOC, GLOSS, GOOS, WMO, WSSI, ADPC, ADRC, JMA, YSB, ESCAP, etc. is also envisaged. Overview 58

shows that annual frequency of earthquakes are increased annually in Myanmar

Slide71: MYANMAR HAS A LONG COASTLINE OF ABOUT 2400 km LONG, WHICH COVERS ALMOST ALL EAST COAST OF BAY OF BENGAL
- THERE IS ABSOLUTELY NO SEA LEVEL OBSERVING STATIONS
ALONG MYANMAR COAST AT PRESENT
- MYANMAR IS SITUATING RIGHT ON THE VERY ACTIVE FAULTLINE
SO CALLED SAGAING FAULT. (THE TOTAL NUMBER IF EARTHQUAKE IN 2004 HAS INCREASED TO ABOUT 220 COMPARING TO LONG-TERM ANNUAL AVERAGE OF 22)
MYANMAR COASTLINE IS VERY CLOSE TO THE FAULTLINE, WHICH LEAVES MYANMAR VERY EXYREMELY LEAD TIME FOR TEW.
- SOME LEADING SEISMOLOGICAL EXPERTS HAVE PERSPECTIVES THAT THE MARITIME EARTHQUAKE POTENTIAL IN MYANMAR WATERS
IS INCREASING AFTER THE SUMATRA EARTHQUAKE.
(HOPEFULLY THEY ARE WRONG
- TO MAKE THINGS WORSEN, OUT OF THEIR THREE PERSPECTIVES
TWO WERE ALREADY PROVED CORRECT.
