the wave destroyed a load of villegesThe 1998 Papua New Guinea earthquake was a magnitude 7.0 event that took place in the early evening on Friday, 17 July 1998. The
earthquake struck the north coast region ofPapua New Guinea , 25 km (16 mi) from the coast nearAitape , and resulted in a large undersea landslide, which in turn resulted in atsunami that swept the coast.Effects
The tsunami resulted in at least 2,183 people being killed, thousands being injured, about 9,500 homeless and about 500 missing. The maximum height of the waves were estimated at being 15 m (49 ft) high with an average height of 10.5 m (34 ft).Cite web |title=The Aitape PNG Earthquake/Tsunami |url=http://www.ga.gov.au/urban/factsheets/tsunami_png.jsp |work=Geoscience Australia |publisher=Australian Government]
The area worst hit was a 30 km (19 mi) coastal strip running north-west from Aitape to the village of
Sissano . Several villages in the path of the tsunami were completely destroyed and others extensively damaged. The village of Arop was situated on a narrow spit between the coast and Sissano lagoon. It was directly in the path of the tsunami and was worst hit.eismology
The earthquake occurred at 6:49pm local time (
UTC+10 ) along the boundary of the Australia and the Pacific tetonic plates at coord|2.96|S|141.92|E. The result from the event was originally thought to have created a two-metre vertical drop in the Pacific Plate along a 40 km (25 mi) long crack.

Royal Australian air Force flew in threeC-130 Hercules transport planes with relief supplies.Cite news |url=http://news.bbc.co.uk/2/hi/asia-pacific/135681.stm |title=Tidal wave kills 'thousands' |publisher=BBC News |date=1998-07-20] In the days following more relief was flown in and afield hospital was set up in the neighbouring town ofVanimo .References
