Abstract
DURING September 1942, thirteen strong earthquakes were registered by the seismographs at the observatory at Toledo. On September 1 there were three shocks, the first beginning with iPz at 9h. 47m. 34s. U. T., attaining an amplitude of 13 µ on the N. S. component at 9h. 52m. 0ls. U. T. and finishing at l0h. 50m. U. T. The shock apparently came from an epicentre distant 2,980 km., the focus being some 250 km. deep. The other two shocks were much smaller. The earthquake on September 6, which registered at 16h. 06m. 34s. U. T., came from an epicentral distance of 9,470 km. and that on September 9, which registered at Ih. 37m. 59s. U. T., from an epicentral distance of 9,245 km. On September 24 an earthquake which began registering at 3h. 56m. 34s. U. T. attained an amplitude of 11 µ at Toledo at 4h. 42m. 46s. U. T. and finished recording at 5h. 10m. 00s. U. T. It came from an epicentre distant probably 11,710 km. The last earthquake registered in the month was on September 26 at 4h. 12m. 09s. U. T., probably from an epicentral distance of 8,465 km., and finished recording at 4h. 50m. U. T. The readings during the month were to a small extent confused by microseisms, and all readings are tentative.
