Actually, it’s the fifth-worst earthquake since 1900. But it’s not the earthquake causing the devastation – it’s the enormous tsunami waves which have killed more than 10,000 people.
I am keeping track of Thailand information at http://www.onethailand.com – so far more than 430 dead, but many missing and thousands injured, I expect the death toll to hit 1,000, and 15,000 for the region.
