AFTERSHOCKS 131 



Sagaing District, Sagaing. — "No detailed record of aftershocks 

 was kept but they continued nearly every day for a month." 



Shwebo District, Shwebo. — " During the next few days there were 

 almost imperceptible tremors at intervals." 



Maymyo, August 12th, 1912. — " The earthquakes are very slight, so 

 slight that many people do not even notice them." — ("Rangoon 

 Gazette.") 



For data regarding most of the aftershocks in Maymyo I' am 



indebted to Dr. Finlavson. Geologist to the 



Afterghockfl in May- Indo _ Blirma p etro leum Co., Ltd. Unfortunately 



he left the station on June Sth and I 

 was unable to find anyone ready to complete the list which he 

 had started. He wrote that the times were taken from a watch 

 correct with the 12 o'clock (midday) gun. As regards aftershocks 

 during the night, the fainter ones, which must have been frequent, 

 would not arouse sleeping persons. The stronger ones were suffi- 

 cient to awake and disturb light sleepers. All the effects were 

 noted and recorded in Messrs. Steel Bros, brick bungalow. 

 Most of the after tremors would fall in degrees I and II of the 

 Rossi-Forel scale and two or three of the tremors in degree III. 

 Reports appeared in the Burma press of July 27th, 1912, 



concerning two slight earthquake shocks felt

(juako of July 26th, m Bassein on the previous day, one at 



1012. 1-54 a.m. and the other at 3-20 a.m. 



Later, the Meteorological Observer in Bassein reported that an 

 earthquake took place at 1-59-58 a.m., and lasted for one second. He 

 was awakened bv the shock which had a shaking movement and cawed 

 hanging objects to swing slightly. No unusual sounds were noticed. 



I do not think that these shocks were in any way connected 

 with the movements taking place in Upper Burma. They are re- 

 garded as purely local and originating either in the Irrawaddy delta 

 or the rocks below it. They belong to the same category as the 

 two Calcutta earthquakes of 190G described by Middlemiss. 1
