Abstract
THOUGH we may have to wait some time for the complete reports on the great Japanese earthquake of March 3, 1933, some valuable papers have recently been published, of which an abstract is here given. The earthquake occurred at about 2.32 a.m., Jap. Stand. Time, on March 3 (5.32 p.m. on March 2, G.M.T.). From the records at stations connected with the Earthquake Research Institute, Prof. Ishimoto finds the epicentre to be in lat. 38.2° N., long. 144.0°E.; while the observations at Tokyo, according to Prof. Imamura, place it in lat. 38.5° N., long. 143.3° E. The latter point is represented by the more southerly of the two crosses in the accompanying map (Fig. 1), the other being the epicentre of the great earthquake of June 15, 1896. The dotted lines on the map are isobaths in thousands of metres, and the two points, which are about fifty miles apart, both lie near the isobath of 4000 metres or about 2½ miles, on the northern slope of the Tus-caroora Deep, the depth of which exceeds five miles.
