Abstract
DURING the period February 4–April 5, fifteen strong earthquakes were registered by the seismographs at Kew Observatory. The greatest of these were on February 29 and March 9. The shook of February 29 began recording compressionally at 16h. 40m. 22s. G.M.T. from an epicentral distance of 8,900 km., and after a full suite of pulses beginning with iP attained a ground amplitude at Kew of 110 μ at 17h. 18m. 53s. G.M.T. On March 9 the shock began recording impulsively at 22h. 13m. 06s. G.M.T. and attained a maximum ground amplitude at Kew of 420 μ at 22h. 43m. 49s. G.M.T. At Toledo (Spain) during February, twenty-four earthquakes were registered by the instruments. The greatest of these was on February 1 at 03h. 28m. 26s. from an epicentral distance of 3,700 km. (Turkey). This shock attained a maximum ground amplitude of 1150 μ at Toledo at 03h. 40m. 44s. Many after-shocks of this earthquake were recorded at Toledo during the month. Earthquakes which registered both at Toledo and Kew occurred on February 1, 4, 5, 16, 20 and two on February 29, the last of these having been mentioned above.
