Abstract
DURING June 1942, eight large earthquakes were registered by the seismographs at Wellington, Auckland, Christchurch and Arapuni, according to Provisional Bulletin No. P-124 of the Dominion Observatory, Wellington. Two prominent shocks were on June 6 with epicentre east of the New Guinea region and focal depth about 100 km., and on June 24 at Wairarapa. Thirty-one local earthquakes were recorded during the period, including the Wairarapa shock mentioned above. This reached intensity 7 on the instrumental magnitude scale (New Zealand Bulletin P-104, p. 3) and was followed by nine principal aftershocks and about 418 minor shocks. Several of the aftershocks reached intensity 4½, and on June 25 an earthquake of intensity 4 was felt at Hokitika.
