Abstract
ONE of the greatest earthquakes for several months past occurred on February 1. The first movements were recorded at Kew at 7 h. 19 m. 52 s., p.m., and the largest oscillation about three-quarters of an ' hour later. According to Mr. J. J. Shaw, it was a very deep-seated earthquake. The records at Kew and Bombay show that the distances of the origin from these two places are respectively 8,250 and 4,250 miles. Thus, the earthquake occurred in the Banda Sea in about lat. 5° S., long. 130° E., at 7·5 p.m., G.M.T. (February 2, 1.45 a.m., local, time). Three earthquakes, with a focal depth of about 260 miles, occurred close to the spot indicated (in lat. 5·5° S., 130° E.) on May 10, 1920, and March 23 and 24, 1921 ; while two others, with the same focal depth, originated in a centre lying five degrees to the east on October 10, 1921, and February 19, 1923. Both foci lie close to the great arc of Sumatra, Java, Sumbawa, Flores, etc., along which many other earthquake centres, deep-seated and otherwise, are clustered.
