TWO strong distant earthquakes have recently been recorded at Kew Observatory. The first, on April 8, 1942, began recording on the vertical component at 15h. 53m. 58s. U. T. impulsively, and on the N and E components at the same time P was emergent. The shock probably originated some 11,000 km. distant, at maximum attained an amplitude of 410 µ at Kew, and finished recording at 19h. 20m. U. T. The second, on April 13, began recording impulsively on all three components at 07h. 55m. 48s. U. T. from an epicentral distance of 6,130 km., attained a maximum amplitude of 94 µ and finished recording at l0h. 00m. U.T. All readings are tentative.
