Abstract
THE United States Coast and Geodetic Survey, in co–operation with Science Service and the Jesuit Seismological Association, hasdetermined the provisional epicentre of the earthquake of July 3 at 7h. 11.7m. U.T. as being at lat. 33° S., long. 68° W. The calculations have been based on reports from eleven seismograph stations. The epicentre is situated near the railway line about midway between Mendoza and San Luis. Activity in this region has been much less severe and more infrequent than between 1750 and 1910. There was a strong earthquake at Mendoza on May 22, 1782, though this was surpassed by the terrific shock in the same area which caused widespread destruction on March 20, 1861. Prior to this latter shock, San Luis was odestroyed on April 9, 1849. Further intense shocks were experienced in both places up to about 1910. It may be that, following the catastrophic shock of January 24, 1939, at Chilian in Chile (NATURE, Feb. 11, 1939, p. 230), the centre of activity has moved eastwards. The earthquake of July 11, 1941, at Ih. 16.6m. U.T. had its epicentre in the Pacific Ocean between the Galapagos Islands and the Isthmus of Panama.
