On Wednesday, one of the most powerful earthquakes ever recorded hit a sparsely populated region in far-east Russia.
It triggered a tsunami that started crossing the ocean at hundreds of miles an hour. What followed was a race against time: early warning systems went into alert mode as waves fanned out towards the coastlines of Japan, Hawaii and the US west coast.
