A tsunami in south-central Chile
From May 21 to 27, 1960, the biggest earthquake swarms occurred
at the bottom of the south-central ocean in Chile and triggered
a huge tsunami. The largest earthquake was of magnitude 8.9 and
the earthquakes caused serious secondary disasters.
The tsunami, which formed waves up to 30m above Chile’s surface,
swept unaccountable surrounding houses and buildings and half of
the buildings in the city became ruins. Besides, more than 100 dams
slong the coast of Chile was destroyed, more than 2000 ships was damaged,
causing economic loss of $550 million. The tsunami killed tens of
thousands of people and left 2 million people homeless.
At the time, waves swept across the Pacific at the spedd of
600-700 kilometers per hour and people were caught in the waves
in a very short time. Some of the people who were caught in the waves
were swept into the depths of the ocean, some were swept up into the
sky by turbulent wave and others were swerved to banks by huge waves.
The height of waves can still reach up to 4m when hit Japan,
killing 800 people, destroying over 1000 residential buildings,
submerging more than 20000 hectares fields and leaving
150,000 people homeless.
