Magnitude 8.6 earthquake sparks tsunami
FROM NEW SCIENTIST:
A major earthquake has struck off the west coast of Sumatra in Indonesia.
Initial automated assessments rated the quake as a magnitude 8.9, but it is now thought to have been an 8.6. It struck at 0838 UTC this morning, approximately 400 kilometres south-west of the Sumatran mainland, at a depth of 33 kilometres.
The Pacific Tsunami Warning Center has confirmed that a tsunami has been generated and “may already have been destructive along some coasts“. A tsunami detection buoy in the Bay of Bengal has now detected a wave with an amplitude of 30 centimetres.
The latest quake is in the same region. “A lot of the damage last time was due to the tsunami,” says Julian Bukits of the British Geological Survey.
