Abstract
DURING June 1943 thirteen earthquakes were registered strongly by the seismographs at Kew Observatory. The strongest of these was on June 9. The shock began registration with iP at 03h. 19m. 56s. U.T. and attained a maximum amplitude of 420 [A at 04h. 09m. 55s. TT.T. on the vertical component at Kew. It is estimated to have come from an epicentre some 10,700 km. distant. This earthquake was registered at Stonyhurst at 03h. 20m. 40s. TJ.T., beginning with eP. Three shocks were registered at Kew and Stonyhurst on June 13. The first was by far the greatest. It recorded iP on all three components at Kew at 05h. 23m. 59s. U.T., apparently coming from an epicentre some 9,100 km. distant. The first recording was compressional and the maximum amplitude at Kew was 270 pi at 06h. 00m. 45s. TJ.T. on the N component. Stonyhurst recorded the shock at 05h. 24m. 10s. TJ.T. The other two shocks on June 13 were probably aftershocks from the same epicentre. The German News Agency reported a shock on June 12, recorded at Wurttemberg Observatory at 6.22 a.m., and believed to have taken place in the Eastern Alps, but this movement was not significantly recorded at Kew.
