Tsunami among world's worst disasters
Hurricanes have also wrought devastation on a huge scale
The massive tsunami in the Indian Ocean has been described by relief experts as one of the worst natural disasters in recent history.
With a likely death toll of well over 250,000, the wave is particularly notable for the extent of its reach, from Indonesia in the east, to the coast of Africa, some 7,000km (4,000 miles) away.
The high numbers of Westerners  affected and the speed at which footage from the disaster reached television screens also added to its impact.
The highest death toll from a tsunami until now happened in 1896, when 27,000 people were drowned following an earthquake off the coast of Japan, according to the Guinness Book of Records.
Cyclones and famine
But there have been other natural disasters which have also claimed tens of thousands of lives.
In 1970, up to 500,000 people were killed in Bangladesh when a cyclone whipped up winds of 230 km/h which swept away entire villages.
