Three hours to disaster: Tsunami modeling reveals the countdown to disaster when natural disaster strikes the east coast of Australia
- The Environment Department of Queensland said the state could be affected within three hours
- The Gold Coast and Sunshine Coast were expected to suffer from a tsunami
- After the first wave, tests showed that it could only take an hour for flooding
Some areas on the east coast of Australia have only three hours to evacuate in the event of a catastrophic tsunami, researchers said.
Modeling performed by scientists from the Queensland Environmental Service showed that parts of the state could be destroyed within three to 17 hours of a warning.
Researchers also discovered that if a wave hit the northern tip of the state, it would only take four hours before parts of the mainland were flooded.
Fraser Island would be the first to be hit, with waves engulfing the popular tourist attraction in just three hours.

Using computer-generated tests, scientists were able to see that tsunamis in the Vanuatu area would hit the Queensland coast the fastest.
They tested potential tsunamis from three different locations, the Vanuatu region, South America, and the Kermadec-Tonga region near New Zealand, in 23 different scenarios.
"We have selected scenarios that are very rare and unlikely to occur, but that could produce a result from which we can draw conclusions," said Paul Boswood, Department of Environmental Engineering's hydraulic engineer. ABC.
Boswood said the tides also had a major impact on the possible destruction of a tsunami along the Queensland coast.
Tests have shown that areas like Moreton Bay in southeastern Queensland can suffer significant damage with waves up to 10 meters. (pictured model of Moreton Bay in a tsunami with red areas indicating the highest waves)
& # 39; We have looked at different tidal stages, because naturally the tide also plays a role. If you look at tsunamis that are only 1 meter high and you have tides of 2 meters, it has an impact, & he said.
Researchers said the Great Barrier Reef may prevent some tsunami destruction, but more exposed areas such as the Gold Coast and Sunshine Coast may suffer the most.
The modeling also showed that Moreton Bay, in southeastern Queensland, could suffer considerable damage in the unlikely event of a tsunami.
The waves in this area can reach up to ten meters and currents can move at 8 meters per second if floods occur.

Noosa and Maroochydore turned out to be the riskiest areas along the Sunshine Coast.
The report said these communities would be relatively safe if a tsunami hit, as long as they were not near beaches and waterways.
Fraser Island was also expected to be hit with models with waves of up to seven meters and currents at nine meters per second.
Queensland regions with the highest tsunami risk to:
- Gold coast
- Ocean side of Bribie,
- Moreton and Stradbroke Islands
- Sunshine Coast
- Fraser Island
- Flying Fishing Point
- Capricorn coast
- Agnes Water
- Hervey bay
