Abstract
THE U.S. Coast and Geodetic Survey, in co–operation with Science Service and the Jesuit Seismological Association, has determined the provisional epicentres of two recent strong earthquakes. The first on April 20, 1941, at 17h. 38.3m. G.M.T., had an epicentre near lat. 37° N., long. 69° E., which is in Afghanistan and some 160 miles north of Kabul. The second, on April 21, 1941, at 2h. 54.lm. G.M.T. was near lat. 53° N., long. 166° W. which is in the neighbourhood of the Aleutian Islands. Both these areas are well known to be frequented by earthquakes, the Aleutian Islands area having been particularly active in recent months.
