ISOSEISTS. DISTRIBUTION OF INTENSITY, ETC. 97 



The shock certainly appeals to have boon split up into 3 or 4 

 separate periods, each with a maximum intensity of its own, but 

 diverse surface conditions, and. perhaps, subconscious personal idio- 

 syncracy, have obscured this in some places. 



Isoseists VI and VII. 



The area circumscribed within the grouped isoseists VI and 



VII amounts to approximately 82,900 square 



Area and bound* ^^ and jjj^ ^ j^ grouped areas IV and 



V. and II and III, it is bounded by a smooth 

 curve joining up the somewhat isolated places from which accounts 

 were received (PI. No. 7). The detailed accounts of the shock have 

 already been given, and it only remains to summarise them briefly 

 here. ' As a glance at the map will show, these grouped isoseists 

 contain the headquarter towns of Monywa, Katha, Bhamo, Myingvan, 

 Pakokku, ToungOO, the southern part, of the State of Karenni, and 

 a belt of country comprising the eastern portions of the Northern 

 Shan States and the central portions of the Southern Shan States. 

 Unusual sounds were still heard in some places, and many 



buildings were cracked, but not sufficiently to 

 Cracking of build- pausp oven j )art j a i destruction or the widespread 



fissuring of all brick structures as found in 

 the area of higher intensity. Cracking of walls though common 

 in some places, is by no means universal and has generally taken 

 place near doors or windows. An occasional brick nogged panel 

 has dropped out, plaster has often fallen, and old pagodas have 

 had part of their tops carried away. 



The shock seems now to have lost a good deal of its sudden-

 shock. It is described as follows : — 



(1) The observer could not follow a straight line in walking 



and lost the sense of height in stepping. He became 

 intenselv giddv and experienced the sensations associ- 

 ated with sea sickness. High trees swayed. A wooden 

 bungalow creaked and groaned and dogs rushed out and 

 barked. 



(2) Cooking pots and cups were thrown over, hanging lamps 



swung.
