1026* Memoir on Indian Earthquakes. [No. 144. 



to the Earthquake, was in strong gusts. The horizon was hazy, but 

 there were no clouds, and no noise was heard : the motion was appa- 

 rently perpendicular, and if any thing from the North to the South. 

 It continued for a full minute, and was the most severe many persons 

 say, they ever felt. Books moved from their places on the table, the 

 tent was literally shaken, and the mangoe trees appeared as violently 

 agitated as if a branch had been seized and shaken for the purpose of 

 throwing off the fruit : a palanquin in the tent moved, and it was with 

 difficulty we could stand on the ground. My bearer actually laid hold 

 of the kandt of the tent, and every one became sick, as if he had been 

 at sea : but the most extraordinary circumstance is, that though the 

 Earthquake was equally strong and perceptibly felt to the Southward, 

 none of my parties who were detached to the Northward three or four 

 miles felt it. The shock was so strong and continued, that I sent to a 

 village, distant about a quarter of a mile, to know if any accident had 

 happened, and was informed, that although the people were much 

 alarmed, no damage was sustained. *********. 



B. 



P.S. — Since writing the above, I have heard that at a large village 

 called Khanpur, three miles South-west of this, the people ran out of 

 their houses for fear of their tumbling down, and some stones fell from 

 the Northern gate. 



The observer in this case was situated considerably to the Westward 

 of Delhi, and judging from the circumstances detailed, near to the 

 Northern limit of the shock. Southward from the position the in- 

 tensity was greater, but the Southern limit is undefined. From 

 other evidence I have stated my conviction to be, that the local Delhi 

 shocks have their focus in the Aravulli mountains, about twenty or 

 thirty miles South-west of that city, and the details connected with 

 the present shock, lead me to believe it emanated from the same 

 locality. The line of greatest intensity would then be to the South- 

 ward of the observer, as it actually was, and although the direc- 

 tion of the motion seemed to be from North to South, while it ought, 

 on the above supposition, to be from South-west to North-east, yet as 

 the observer writes with hesitation on this point, he may very possibly 

 have been mistaken. My own opinion certainly is, that the Earthquake 

 of the 24th October 1831, emanated from the Aravulli range, and was 

 a primary, although a local, and by no means, a widely extended shock. 



For upwards of ten years another blank occurs, during which, no 

 Earthquakes of the Aravulli tract are recorded. During the year 

 1 842, no less than eight were experienced, as noted in Part I of this 

 Memoir, so that the disturbing forces must have been unusually active 

 in that year, unless their previous inactivity may be due only to our 

 want of information on the subject, a circumstance by no means im- 

 probable. As I have noted all details relative to the shocks of 1842 

 in the Register, I need only recapitulate their dates here, combining 

 with them, the others of the tract, so as to give the whole at one 

 view : —
