The Pacific Ocean experiences more
tsunamis than anywhere else in the world. Tsunamis have also occurred
in the Caribbean and Mediterranean Seas, and the Indian and Atlantic
Oceans.
In
1775, the Lisbon earthquake created a tsunami in the North Atlantic
that killed as many as 60 000 people in Portugal, Spain and North
Africa. This quake caused a tsunami as high as 23 feet in the
Caribbean.
The
December 2004 Asian tsunami is the deadliest in recorded history with a
death toll of nearly 300,000. It was triggered by the fourth most
powerful earthquake since 1900, estimated to measure 9.15 on the
Richter scale.
Many
people were killed by the Asian tsunami because they went down to the
beach to see the exposed seafloor caused by the retreating of the
ocean. If you see the ocean receding unusually quickly or far it’s a
good sign that a big wave is on its way.
The
Indian Ocean tsunami travelled as much as 3,000 miles to Africa and
still had enough force to cause enormous destruction. For example,
Somalia was hit harder than Bangladesh despite being much further away.
Before
2004 the most damaging tsunami on record was in 1782, following an
earthquake in the South China Sea, which killed an estimated 40,000
people.
In
the Pacific there were 17 tsunamis from 1992 to
1996 and they claimed nearly 1,700 lives.
An
earthquake off the coast of Chile in 1960 produced
a tsunami that had enough force to kill 150 people
in Japan after a journey of 22 hours and 10,000
miles.
Prior
to the Asian tsunami, the most deadly tsunami in recorded history
followed the eruption of Krakatoa in 1883, which destroyed the volcano
completely and killed more than 36,500 people across the South Java Sea.
