New Scientist Breaking News - Indian Ocean tsunami's puzzling waves explained:
The tsunami that ricocheted around the world following the Indian Ocean earthquake on 26 December 2004 left a puzzling pattern of waves in its wake.
Beaches in Peru and Mexico, nearly 20,000 kilometres from the earthquake, received waves that were three times larger than those hitting the shores of the Cocos Islands, just 1700 km away. Now it turns out that the waves were funnelled along underwater structures, such as mid-ocean ridges and continental shelves.
