By EARTHQUAKE SHOCKS AT PALIYAD IN KATHIAWAR. PART I.—THE EARTHQUAKES AND THEIR CAUSES. A series of earthquake shocks has recently been experienced near Paliyad (22° 15': 71° 33') in Kathiawar. The shocks began on the 26th June 1933, and were still con Introductory. tinuing on the 15th August, 1938 the last day for which earthquake reports have been received. The shocks varied greatly in intensity, but were on the whole light. The heaviest occurred on the 12th July about 3:45 P.M., on the 20th July about 4-20 A.M., and on the 23rd July about 5:35 P.M. As will be seen from the table below, the earthquake activity seems to have reached its maximum on the 23rd of July, and to have thereafter decreased. So far as I could ascertain, the earthquake damage up to the 23rd July was confined to the collapse of a weak mud wall in Paliyad on the 12th, and to minor cracks and falls of plaster on the 20th. About 5.35 P.M. on the 23rd, however, a on the 23rd, however, a severe shock did much damage in Paliyad (see p. 590). This was felt by most people as far away as Viramgam, Bhavnagar, Morvi and Rajkot, that is over an area of at least 4,000 square miles. |
