124 COGGIN BROWN: TfitE BUttMA KARTIIQIAK ES OF MAY 1912. 



A study of the distribution of the intensity of these earlier 

 shocks, from such scanty data as are 



ori gin . Al available, leads me to the conclusion that 



their origin is probably identical with that of 



the great shock of May 23rd, and is to be sought for in or about 



the Kyaukkyan fault.

Bhooks. an(l °tner places seems (o have been in an 



almost continual state of tremor. 1 was 

 informed by residents in Maymyo that it was impossible to chronicle 

 all the aftershocks which were felt, and when 1 visited the station, 

 almost imperceptible tremblings of the ground were a repeated 

 occurrence. The list given below is very incomplete and can only 

 show a small percentage of the actual number of aftershocks. Main 

 were slight enough to be hardly felt at all, while others attained a 

 fair degree of strength. Yet although admittedly incomplete, the 

 list shows how the shocks gradually became less frequent, of lower 

 intensity, and more localised in the Northern and Southern Shan States, 

 and in the Mandalay and Ruby Mines districts around Maymyo, 

 Taunggyi and Mogok.

 the most severe one experienced since the bad shock of last

 which increased in volume as it approached and finally died away "
