1052 Memoir on Indian Earthquakes. [No. 144. 



The following summary by James Prinsep, Esq. may appropriately 

 conclude the detail of the Earthquake under review. 



" The direction of the vibration was from North-west to South- 

 west : there were three principal shocks ; the first about half-past six 

 p. m. ; the second at half- past eleven ; and the third, or most severe 

 shock, at about five minutes to twelve, Calcutta time. In the places 

 where it was most felt, slight and continued vibrations seem to have 

 been experienced for the whole of the day following. As the time of 

 the second vibration was accurately noted in Calcutta by the stopping 

 of an astronomical clock, we may assume it as the best point of com- 

 parison with the times noted at other distant points. Applying the 

 difference of longitude, a few of them may be thus classed : — 



Observed Time. Diff. Long. Cal. Time. Effects. 

 Katmandu, Nepal, second shock, lOh. 45* + ^ m * == 'Oh. 57m. Very severe, with 



loud noise. 

 ..11 20 — 2 =11 18 Many houses injured, 



loud noise. 

 ..11 27 + 7 =11 34 Walls cracked, noise 



heard. 

 .. 11 15 +14 =11 29 Walls injured, loud 



noise. 

 ..11 10 +20 =11 30 



..11 20 +19 =11 39 Walls cracked &c.&c. 

 ..11 + 28 ='l 28 Hollow sound from 



4 the river. 



.. 11 30 + =11 34 None such since 1814. 



= 11 34 48 No injury done. 



At Monghyr, Rungpur, Mozuffurpur, Mallai, and other places with- 

 in direct line of influence, many houses were destroyed or injured, and 

 the alarm was great. 



As all comment on the phenomena of this shock is reserved to a 

 future period, I need only now state, that I am not aware of any Earth- 

 quakes having occurred in Nepaul since 1833. I ought however 

 before this to have mentioned that in 1829, daily shocks continued to 

 recur for 40 days, although none were equal in intensity to that of the 

 26th August, 1833. The following Register of the shocks that followed 

 the great one of the 26th was kept at Katmandu by Captain Robinson. 

 Regarding them Dr. Campbell remarks : " Many of them have been 

 severe, and throughout the whole course of these visitations, there 

 have been two distinct varieties observed in the character of the shocks, 

 all those at the commencement were of the undulatory or swinging 

 kind : the others wanted the swell, and were a violent up and down 

 shaking, with little lateral motion. The first may be called the hori- 

 zontal, the latter the vertical variety. The former alone have been 

 destructive to property, while the latter, from the greater noise by 

 which they are accompanied, and the more rapid oscillations of the 

 ground, are perhaps the more terrifying. 



* Time marked by a good going clock, which was stopped by the third shock. Its 

 pendulum vibrated from North to South.
