Abstract
DURING November 1942 ten earthquakes were registered by the seismographs at Auckland, Arapuni, Christchurch, Kaimata, New Plymouth, Tuai and Wellington, according to a seismological report just received (Prov. Bull. No. P-129, November 1942, Dominion Observatory, Wellington W.I, New Zealand). The greatest was on November 10 when the trace amplitude on the Z record was 12 mm. This earthquake began recording with P compression at llh. 53m. 45s. U. T. from an epicentral distance of 82° and from an azimuth south-south-west of Christ-church. The shock of November 3 had a focal depth of 350 km., and the next deepest focus occurred on November 7 (180-200 km.). The most intense of the twenty-six earthquakes felt during the month in New Zealand had intensity 5 on the Rossi-Forel scale. This occurred on November 26 at Ih. 3146m. U. T. from an epicentre near latitude 41° S., longitude 172.3° E. Masterton was most often affected during the month, and Wellington experienced three small shocks on November 3, 7, and 14.
