Abstract
VALUABLE data concerning earthquakes during the period October-December 1940 have just been received from the Riverview College Observatory, New South Wales (director, D. J. K. O'Connell, S.J.). During this period sixty-three earthquakes were registered and interpreted, eleven giving a maximum amplitude greater than 2 mm. The greatest amplitudes were on November 27, 1940, when an amplitude of 7-3 mm. was recorded by the north-south component seismograph and 9-0 mm. by the east-west component. This earthquake was felt at Neinduk, at North Baining with intensity 6 on the Rossi-Forel scale, at Kavieng R.F. 5 and at Rabaul R.F. 4-5. The earthquake of November 22, 1940, which only gave a maximum amplitude of 0-5 mm. at Riverview was felt at Rabaul, New Britain R.F. 4, Neinduk R.F. 3, Pondo R.F. 5 and Kuridui R.F. 4. Microseisms prevented the interpretation of some seismograms on which the earthquakes only recorded with small amplitude.
