REALITY CHECK: BIG EARTHQUAKES

THE GUARDIAN has a lot of interesting data about past earthquakes such as: "the most deadly earthquake to strike over the past 110 years hit Tangshan in China in July 1976. Measuring 7.5, the quake caused 255,000 deaths.

Over the past ten years the world has averaged about 15 earthquakes a year that were strength 7.0 or higher and about 1.4 a year that were strength 8.0 and higher. The world has average about 26,000 earthquakes a year with last year's total - 14,788 - being the lowest of the decade. If earthquakes continue at the rate of the first two months of 2010 the figure for the year will be even lower - around 10,000.

Death rates vary markedly, however, ranging from the over 200,000 this year and in 2004 to only 712 in 2007.
