(b) Fig. 2.2 is a website report of a tsunami which occurred on 2 April 2007. 6 Dozens feared dead in Solomon Islands tsunami Papua New Guinea Pacific Plate Solomon Islands N Indo-Australian Plate Australia 0 km 500 Key direction of plate movement Dozens of people are feared dead in the Solomon Islands, after an under-sea earthquake caused a powerful tsunami to sweep across the South Pacific. The earthquake, and a series of aftershocks, prompted a tsunami alert across much of the Pacific region. The earthquake, measuring 8.0 on the Richter scale, sent a wall of water five metres high crashing over coastal villages in the west of the low-lying islands. The islands are popular with international travellers for scuba diving. Most homes in the islands are constructed of timber and bamboo, with villagers relying on fishing and logging for their livelihood.
