Disaster Prevention and Mitigation Department warns tsunami to hit southern coast at 5:09 pm

The Nation

BANGKOK: -- The Disaster Prevention and Mitigation Department has issued an urgent warning for people living on the coast of six southern provinces to evacuate, the areas would be hit by tsunami starting from 5:09 pm.

Anusorn Kaewkangwal said residents of Ranong, Phang Nga, Phuket, Satun, Krabi and Trang were told to clear the coastal areas before 5 pm.

He said Koh Miang of Phang Nga would be the first to be hit by tsunami at 5:09 pm.

Then, the giant waves would hit Karon and Patong beaches in Phuket and Phi Phi isalnd in Krabi and Jao Mai and Paliang beaches in Trant. Ranong and Satun would be hit by the giant waves later, Anusorn said.

.....I don't see anything to joke about.....to each his own.........40 cm.....1000 km away......

As the tsunami crosses the deep ocean, its length from crest to crest may be a hundred miles or more, and its height from crest to trough will only be a few feet or less. They can not be felt aboard ships nor can they be seen from the air in the open ocean. In the deepest oceans, the waves will reach speeds exceeding 600 miles per hour (970 km/hr). When the tsunami enters the shoaling water of coastlines in its path, the velocity of its waves diminishes and the wave height increases. It is in these shallow waters that a large tsunami can crest to heights exceeding 100 feet (30 m) and strike with devastating force.

Tsunamis are characterized as shallow-water waves. Shallow-water waves are different from wind-generated waves, the waves many of us have observed on a the beach. Wind-generated waves usually have period (time between two sucessional waves) of five to twenty seconds and a wavelength (distance between two sucessional waves) of about 100 to 200 meters (300 to 600 ft). A tsunami can have a period in the range of ten minutes to two hours and a wavelength in excess of 300 miles (500 km). It is because of their long wavelengths that tsunamis behave as shallow-water waves. A wave is characterized as a shallow-water wave when the ratio between the water depth and its wavelength gets very small. The speed of a shallow-water wave is equal to the square root of the product of the acceleration of gravity (32ft/sec/sec or 980cm/sec/sec) and the depth of the water. The rate at which a wave loses its energy is inversely related to its wavelength. Since a tsunami has a very large wave length, it will lose little energy as it propagates. Hence in very deep water, a tsunami will travel at high speeds and travel great transoceanic distances with limited energy loss. For example, when the ocean is 20,000 feet (6100 m) deep, unnoticed tsunami travel about 550 miles per hour (890 km/hr), the speed of a jet airplane........

...anyone still laughing???

Let's hope that it dissipates....

Nothing wrong with a little light hearted banter to break up the tension or is required to be absolutely in high panic mode? Stay calm and think clearly, take a deep breath..

'But Bruce Presgrave of the USGS later told the BBC that the nature of this quake made it less likely a tsunami would be generated, as the earth had moved horizontally, rather than vertically, therefore had not displaced large volumes of water.

"We can't rule out the possibility, but horizontal motion is less likely to produce a destructive tsunami," he said.'

is there a possibitlity that it will affect koh chang? i need advise as i am leaving for koh chang tomorrow.thanks

If you are not going there until tomorrow, suggest you just monitor the news - nobody knows anything for certain right now except for one thing... if the Tsunami hasn't hit after 3-4hrs then its probably not going to hit.
