| Researchers have discovered that January's huge quake in Haiti caused a tsunami (海啸). Along with four Haitian colleagues, Dr Hermann Fritz, a professor, travelled around the coast of Haiti. He wanted to find out what had happened before the evidence disappeared forever. He had heard reports and saw evidence that a wave up to 3-meter high had hit some areas of the coast south of the capital following the quake near Port au Prince. It had killed at least three people and engulfed (吞没) buildings. Dr Fritz presented some of his findings at the Ocean Sciences meeting in Portland in the US. "This was a relatively small event," he told BBC News." Most of the deaths were due to the earthquake, but at least three victims we know survived the earthquake and were hit by the wave." These three victims were a father and his two young sons. They were standing close to the shore in Petit Paradis, watching the wave instead of heading for higher ground. Draw-back in the water level is a sign that a big wave is coming. "It clearly showed a lack of tsunami education," Dr Fritz said. "It was pure luck that the wrong information did not kill more people in this case." Despite the great damage it caused, the Haiti earthquake was not of the type or magnitude (级) usually associated with tsunamis. It had a magnitude of 7.0. "Generally anything over 7.5 is cause for concern," explained Eddie Bernard, a tsunami researcher." But anything between 7 and 7.5 can cause smaller, local tsunamis." It also occurred on land and, to cause a tsunami, it must happen under the sea. "Anything that moves water generates a wave," said Dr Bernard. "And the deeper the event, the bigger the wave." Dr Fritz explained that the main causes of the Haitian tsunami were "local landslides". "'But there are fault lines in this region that are in areas which are more likely to cause a tsunami and, if you have a much bigger landslide, you could have a much bigger wave," he said. |
