Abstract
FOUR large earthquakes have been recorded at Kew in the period March 23-April 13. The first was received at 22h. 41m. 17s. G.M.T. on March 28 and may have been from an epicentre 19,000 km. distant, though the initial movements were confused by microseisms. The second was at lOh. 52m. 19s. on April 1, probably from an epicentre 7,870 km. distant, while the third, at 15h. 34m. 31s. G.M.T. on April 3, had its epicentre 9,180 km. away. This latter had a particularly prominent wave on all three components at 15h. 33-5m. G.M.T., which may have been eSSS. An earthquake giving a full suite of pulses had iP dilatational at 23h. 40m. 27s. G.M.T. on April 7 and did not cease recording until 3h. 20m. G.M.T. on April 8. It probably had its epicentre 7,920 km. distant from Kew, though all calculated epicentral distances are tentative.
