The tsunami claimed many lives normally, so there should be an early warning to the public. Although technology can already predict some disasters but it never hurts to recognize the signs before the tsunami disaster in particular, in order to immediately secure the self.
The tsunami is a series of waves caused by landslides or large earthquakes that occur both on land and at sea. The tsunami waves can occur 5 minutes to 1 hour after a landslide or earthquake.
Here are some early signs of the arrival of the tsunami disaster, as reported by eHow, namely:
1. Beginning of earthquakes
If you live near the coast, should be careful when an earthquake. Tsunamis usually occur because of earthquakes occurring below or near the sea. Not only are earthquakes that occur in your area, but also around the world. The earthquake thousands of kilometers away can cause potentially deadly tsunami in your area.
2. Listen to the voices roar
Many tsunami victims have said that the arrival of the tsunami waves will be preceded by a loud roar similar to a freight train.
3. Note the decrease in sea water
If there is a rapid decline in sea water and is not a time of low tide, then immediately seek refuge high. Before the tsunami, the sea will recede quickly first and then come back with enormous power.
4. Always alert in the first wave
The first tsunami wave is not always the most dangerous, so stay closer to the shoreline until the circumstances are completely safe. Do not assume that because a small tsunami at one place it will be small also in other areas. The size of tsunami waves varies and is not the same at all locations. The tsunami waves also can travel through the rivers that connect to the sea.
In addition to these signs, nature can also give a sign before the disaster, such as unusual wind movement, air pressure or extreme weather and animal behavior has changed.
Scientists theorize that animals are able to capture the vibrations or air pressure changes around them that can not be human.
“I do not think that this is the sixth sense, at least none that we can measure at this time,” said Diana Reiss, Ph.D., director of marine mammal research at the Wildlife Conservation Society, based at the Bronx Zoo in New York City, such as reported by FoxNews.
Some bats, which are nocturnal and usually sleep during the day, became very active and a half hours before the tsunami came.
In Sri Lanka and Thailand there is a story about the elephants ran to the hills one hour prior to the 2004 tsunami that destroyed villages and killed up to 150,000 people in both countries.
