Abstract
R.C. HAYES, of the Dominion Observatory, Wellington, New Zealand, read a paper on deep-focus earthquakes of the south-west Pacific at the Sixth Pacific Science Congress in 1939.* The Dominion Observatory at Wellington has for many years carried out the determination of provisional epicentres in the region south of the equator, lying between long. 140° E. and long. 160° W. In the region investigated, it appears that about 11 per cent of all the earthquakes have abnormally deep foci, and that about 60 per cent of the deep ones occur between lat. 10° and lat. 30° S.
