The Sawadi area in Barka will be evacuated as part of the international mock tsunami drill Indian Ocean Wave Exercise (IOWave18) on September 4.

Sawadi region to be evacuated ahead of mock tsunami drill tomorrow

The Directorate General of Meteorology (DGM) has been raising awareness about the physical exercise prior to the drill by means of a series of social media campaigns.

According to the DGM, tsunami in Oman can be triggered by two events, earthquake in the Makran Subduction Zone off the coast of Iran and in the Sunda Trench, west of North Sumatra, Indonesia.

“The Makran Subduction Zone in the Sea of Oman can generate tsunamis in case of an earthquake of more than 7 degrees on the Richter scale. It is considered as the most potent to generate a local tsunami,” the DGM stated.

“The tsunami from East Asia will take about seven hours to reach the shores of the sultanate, while those in Makran Subduction Zone will take a little more than half an hour to reach the shores of Oman.”

According to DGM, an earthquake occurred in the Makran belt on November 28, 1945 which led to the creation of 40ft tsunami on the Pakistani coast.

A tsunami can travel at the speed of a industrial jet plane, more than 800kmph, stated DGM.
The speed of the tsunami in shallow coastal water go slow, causing higher waves up to 15m throughout a distant tsunami and a lot more than 30m for tsunami waves generated close to the epicentre.

“Although the occurrence of tsunamis cannot be predicted but by looking at historical events, scientists can know where tsunamis are most likely to be generated,” it added.
Oman and numerous other nations bordering the Indian Ocean will take component in the huge-scale tsunami simulation physical exercise on September four and five.

The Indian Ocean-wide physical exercise aims to boost tsunami preparedness, evaluate response capabilities in every nation and enhance coordination all through the area.

Coordinated by the Indian Ocean Tsunami Warning Mitigation System (IOTWS) of Intergovernmental Oceanographic Commission (IOC) of Unesco, the IOWave are held each and every two years to boost tsunami preparedness at the neighborhood level.

The physical exercise will comprise two scenarios on successive days that will create simulated tsunami waves travelling across the Indian Ocean basin.
