CHAPTER V. 
THE AREA ENCLOSED BY ISOSEIST No. 5. 
The inforination given for places situated within tliis isoseist is, 
with a few exceptions, derived from the reports of observers, news- 
paper accounts, and the earthquake enquiry-forms. The position 
of the Isoseist is shown on the map (Plate 14). The point of interest 
about it and also about Isoseist No. G is the unexpected curve out- 
wards taken by them in Burma about latitude 21°. At this point, 
instead of continuing symmetrically round the four inner Isoseists, 
they both curve outwards, becoming concave instead of convex 
outwards for a short distance and then curve southwards to embrace 
the subsidiary Arrakan centrum as well as the main Srimangal 
centrum. The information obtained with reference to this area 
is derived from information supplied by local observers, and from 
earthquake enquiry-forms. It is as follows : —

building was more seriously damaged, the upper corners of one of the inner
