Scientists have acknowledged that they overestimate the danger of tidal waves from the earthquake that hit Chile, but defended their actions, saying it had taken the right steps and lessons learned from the 2004 tsunami in Indonesia, which killed thousands of people who are not alert enough.
"It is important point to remember that we are not under caution, and failure to warn was not an option for us," said Dai Lin Wang, an oceanographer at the Center for Tsunami Warning in the Pacific Ocean in Hawaii. "We can not be the situation that we think that there is a problem, and they are devastating. This simply will not happen."
Hundreds of thousands fled to higher ground Saturday in the coast overlooking the Pacific Ocean after flying panic scientists from 53 countries and territories that the tsunami generated by the huge Chilean warned Quak
The largest-scale evacuation in Hawaii for years, if not decades. Sirens in emergency situations throughout the day, move Navy ships at Pearl Harbor and people hoard gasoline and food and water in anticipation of a major disaster. Some supermarkets even placed restrictions on items such as spam because of panic buying.
At least five people were killed by the tsunami in Robinson Crusoe Island off the coast of Chile, the waves destroyed the port city of Talcahuano, near Concepcion was badly beaten on the mainland of Chile.
But the danger of tidal waves that left the sunny beaches of Hawaii hours empty, never appeared - a stark contrast to the tidal wave that 230,000 people around the Indian Ocean was assassinated in 2004 and destroyed entire communities.
This time the waves of more than 5 meters reported in the Gulf of Kahului, Maui, and Hilo, on the east coast of in the major Hawaiian Islands, but little damage. Expectations of high waves in some areas has been shut down by 50 percent.
In Tonga, where up to 50,000 people who fled inland hours before the tsunami, the National Office of Disaster wave of reports from 6.5 meters to save a small island north, with no evidence of damage.
In Japan, where authorities ordered 400,000 people from coastal areas, and was the largest wave 4 - foot boom that hit the northern island of Hokkaido, flooding several pillars.
The Japanese official admitted that the authorities might be too in the issuance of the first tsunami warning key in over 15 years for a wave which eventually caused virtually no damage.
'Tsunami Agency forecasts proved to be a little too big, and I would like to apologize for continuing these warnings and said, "Yasuo Sekita, and meteorology official body responsible for earthquakes and tsunamis, in a press conference.
But scientists have not provided any justification for these warnings, and defended the work, all the while worrying that the false alarms can lead to complacency among local residents - the possibility of catastrophic overlooking the Pacific Ocean in the quake zone.
The quake was similar in Chile in 1960 creating a tsunami that left nearly 140 people have died in Japan. The same increase hit and destroyed the center of Hawaii Hilo, on the Big Island, killing 61 people and the elimination of more than 500 homes and shops.
"If you have a lot of warnings and none of them do, then lose credibility," said Mr. Wang. "This is something that we are dealing with and we must improve."
"I hope everyone learned from this for the next time, and there will be a next time," said Gerard Fryer, Geophysicist, and the warning center.
It was learned from the tsunami is difficult to predict, given the sheer volume of the oceans and the volatile forces at work miles underground.
Scientists use earthquake with a magnitude and location as the basis for their expectations and then continually refine the data from more than 30 sensors in the deep waters of the Pacific, where sweeping the shock wave is based on the ocean floor.
The sensors, located at 15,000 feet to 20,000 meters under the earth's surface, and the weight of water and exposed to buoys on the surface of the water. Then the scientists used data from the tsunami wave height for the open ocean as it progresses in shallow water.
