On the trail of tsunami
Since the 2004 tsunami, scientists have moved closer to understanding and predicting its trigger, the tectonic earthquake. Are governments prepared to benefit from the knowledge?
Ffive centuries the earth OR OVER had struggled to maintain its composure, bowing here and bending there, yet somehow withstanding the mounting pressure.Far beneath the surface,the Indo-Australian tectonic plate was subducting under the Sunda plate, but near the surface these plates had locked together, accumulating historic levels of tension along a huge stretch of the Sunda megathrust. Then, in a decisive moment on December 26, 2004, the earth shrugged off its strain. In a matter of seconds, 1,600 kilometres of ocean floor broke free and lurched upward, like a compressed spring suddenly released. The displacement was later calculated to be as high as six metres. It was this incredible force of displacement that triggered the tsunami of 2004, killing 23,000 people and causing incalculable loss of livelihood.
The 2004 tsunami, that killed over 250,000 people on a single day and affected at least 15 countries, was caused by the most powerful earthquake in 40 years
