Abstract
DURING the first quarter of 1945, fourteen earthquakes were registered by the seismographs at King's College Observatory, Aberdeen, and Dr. A. E. M. Geddes reports that the instruments were not working during March 7–21. The largest shock was on February 10, registered at Aberdeen at 05h. 9m. 48s. G.M.T. from an epicentre estimated distant 77·4°, and developed a maximum ground amplitude on the east component at Aberdeen of 178 μ at 05h. 36m. 11s. G.M.T. At the Dominion Observatory at Wellington, New Zealand, six strong earthquakes were registered during February and five during March. The earthquake on February 26, with epicentre about 77 from Wellington, was a deep-focus shock, the focus being 180–200 km. below the surface of the earth. The earthquake of March 18 had its epicentre south of the Kermedecs, only about 7 km. distant from Auckland, New Zealand. The greatest felt earthquake in New Zealand during February occurred on the 18th and was felt in north-west Nelson with intensity On the modified Mercalli scale of 4. During March fifteen earthquakes were felt in New Zealand, the greatest intensity being scale 4 at New Plymouth on March 11, in the northern part of South Island and the Cook Strait region on March 12, at Wairoaton on March 19 and at Masterton on March 19 (separate shock).
