“…In Figure 9, the combination of curves and triangles in sherd 49 are similar to incised designs from New Caledonia; a comparable situation is likely for the obliquely converging lines in sherd 50 (Sand 1998). The incised lattice motif, also common in dentate, has been found in the Solomon Islands (Donovan 1973). The other incised designs shown in Figure 9 are fairly common, with the exception of the spiral design on sherd 91 that appears to be unique to Naitabale.…”

“…On the basis of motif analysis, the Lapita pottery from Naitabale shows close affinities with assemblages in the Western Lapita Province, notably New Caledonia (WK0013A) (Sand 1998) and the Solomon Islands (RF-2) (Donovan 1973). It also has much in common with the assemblages from the Lapita site at Matanamuani on N aigani Island, 20 km distant (Best 1981(Best , 2002.…”

In 2003 the authors discovered and excavated a Lapita site at Naitabale close to the southern end of Moturiki Island (central Fiji). Today the site is 350 m inland from the coast, but in Lapita times it was located behind the active beach ridge. A large collection of potsherds (including 92 dentate-stamped or incised Lapita sherds), shell, and animal bones was recovered, together with a human burial. Sherd decorations show affinities with the Western Lapita Province rather than the Eastern Lapita Province (which includes Fiji). Temper analyses of 45 Lapita sherds do not show any unmistakably exotic (to Fiji) pottery, but 29 percent are nonlocal to Moturiki and nearby islands. Fish bones are mostly from inshore species (dominated by Scaridae), while nonfish vertebrates are dominated by turtle and include dog and chicken. Shellfish remains are dominated by gastropods, mostly Strombus spp. (43 percent of gastropod MNI). The surf clam (Atactodea striata) accounts for 38 percent of bivalve MNI, with Anadara antiquata and Gafrarium pectinatum each representing 14 percent of the bivalve MNI. The skeleton is that of a woman (Mana) 161–164 cm tall who died at 40–60 years of age. Six radiocarbon dates from bones overlap 2740–2739 cal. years B.P. (790–789 B.C.). The mandible lacks antegonial notches but is not a proper rocker jaw. The cranium was better preserved than any Lapitaassociated skeleton hitherto described, which allowed the head to be reconstructed. Stable-isotope analyses show that her diet contained significant amounts of reef foods but was probably dominated by terrestrial plants. The Lapita occupation of Naitabale is likely to have begun by 2850 cal. years B.P. (900 B.C.). Radiocarbon dates and pottery decorative styles both suggest Naitabale was first occupied within the early part of the Lapita history of Fiji.

What are the main uncertainties in estimating earthquake risk?

The general heading of seismic risk covers a variety of problems, of which the following at least may be distinguished: risk analyses for a particular structure on a particular site;   the determination of large-scale zoning schemes;   microzoning;   risk analyses for earthquake insurance ;   risk analyses for civil defence and hazard reduction programmes.   This paper is concerned chiefly with the first of these, although a few remarks concerning the others appear in the final section. Its intention is to identify the major uncertainties which enter into the estimation of seismic risk (in the sense of 1. above) and to place an order of magnitude estimate on the errors each is likely to cause. Some earlier papers with a similar theme are by Cornell and Vanmarke (1969), Donovan and Bernstein (1978), McGuire and Shedlock (1981), McGuire and Barnhard (1981) among others. Evidently there is a considerable element of personal judgement in such an attempt; the principal aim is to draw attention to the effects of aspects which are difficult to bring into explicit consideration and as a consequence are in danger of being ignored or otherwise brushed under the carpet.
