Abstract
THE United States Coast and Geodetic Survey, in co-operation with Science Service and the Jesuit Seismological Association, has made a preliminary determination of the epicentres of three recent earthquakes in the Pacific Ocean. The first of these, on March 15, 1943, occurred at 4h. 47.9m. TJ.T. at an epicentre near latitude 10° N., longitude 142° B., which is in the bed of the ocean to the north-east of Fuhaesu in the Caroline Islands. The second earthquake, also on March 5, occurred at 22h. 59 .2m. U.T. at an epicentre near latitude 14° S., longitude 174° W., which is in the bed of the ocean to the south-west of Savaii, Samoa, and north-east of Fiji. This earthquake had a depth of focus in the neighbourhood of 300 km. The third earthquake occurred on March 21 at approximately 20h. 35-4m. U.T. from an epicentre near latitude 6° S., longitude 146° E., which is on land hi the north-east of the island of New Guinea. The exact location is just south of Astrolabe Bay and the coast town of Dein. All these earthquakes occurred in well-known seismic regions, and all interpretations and calculations are tentative, the data being received from seismological observatories to Tucson, Sitka, Honolulu, Wellington, Pasadena, Fardham, Sydney, Buffalo, Brisbane and Apia.
