Naragé is a post-explosive-eruption volcanic remnant of approx of what was an island of prior to an eruption that occurred in approximately 1892. The resulting tsunami reached 100 metres on impact on Ningau, wiping out all but two persons of the lowest-lying of three villages - Goru - (they were absent on Garove) and caused major disruption and reduction of population over a wide area of the north coastal areas of New Britain and quite possibly New Guinea and the Western Islands group, plus other islands. A wave of such magnitude would have made the 1997 Itape wave little more than a reef or shore break.
