Saturday's tremor unleashed 50 giga-tonnes of energy and broke up about 250 miles of fault zone.The epicentre was 140 miles north of the largest quake ever recorded - a magnitude 9.5 that killed 1,600 people in Chile and scores of others in the Pacific in 1960.And the force of the mega-quake
was felt as far away Brazil - 1,800 miles to the east although fears of a devastating tsunami across the Pacific receded yesterday.
