1843.] Memoir on Indian Earthquakes. 1051 



Pass from the valley of Nepaul.) From Tingri to Kirung, a distance 

 of 8 or 10 marches, the route is nearly due West, running along and 

 through the Northern side of the Himalaya ; and throughout this tract, 

 though but thinly inhabited, authentic reports of the occurrence orthe 

 shock were received. By Kirung (the Eastern Pass from the valley 

 into Bhote) the mission penetrated the great range, and at each stage 

 (four in number through the Pass) intelligence of the occurrence was 

 communicated by the few individuals who inhabit that wild and sterile 

 region. But such information was not required, as its effects were 

 sufficiently manifest : in the village of Kirung, itself, supposed to 

 consist of 400 houses, 60 were fairly demolished, and many more 

 seriously injured: two men had been killed under the ruins of their 

 houses, and about a dozen wounded. From the exit of the Pass to 

 Katmandu there are no towns along the route, and scarcely any 

 villages : but at many places, insulated houses of the mountaineers had 

 been thrown down, and the precipitous banks of hills and mountains 

 had been thrown into the subjacent valleys. 



Tingri, therefore, in latitude 28° may be fixed upon as the extreme 

 Northern limit of the influence of the shock, and 1 now proceed to 

 trace its progress in other directions. Before, however, quitting the 

 valley of Nepaul, I may mention as an interesting fact, that torrents 

 of rain fell immediately after the Earthquake, washing down many of 

 the walls which had previously been only shaken. 



In tracing the course of the Earthquake to the westward of Nepaul, 

 the diminution of its intensity is remarkably exhibited. At Gorkha, 

 Dr. Campbell mentions, that only two houses were destroyed ; at Palpa 

 farther to the Westward, none ; and at Doti on the borders of Kemaon, 

 the shock was felt, but by no means severely. At Lohooghat in 

 Kemaon, Dr. McClelland states, that it was scarcely felt at all, so 

 slightly indeed, that he himself was unconscious of its occurrence, 

 although it was perceived by a friend on whose authority he registered 

 it. In the mountains, therefore, the influence of the Earthquake ap- 

 pears, in so far as shewn by the information recorded, to have extend- 

 ed from the meridian of Lohooghat, about 80° E. to that of Tingri, 

 about 87° E. or over about 7° of longitude. In the plains, however, it 

 extended considerably farther both to East and Westward. In the 

 latter direction, the extreme point appears from the published accounts 

 to have been Delhi, in longitude 77° 16' E., or nearly 3° farther to the 

 West than Lohooghat. Toward the East, the boundary was the 

 meridian of Chittagong, 91° 42' E. in the Plains, or nearly 5° to the 

 Eastward of Tingri, which so far as we know, formed the corresponding 

 limit in the mountains. The Southern line appears to have been 

 nearly the parallel of 22° N. latitude. Thus then the entire range of 

 the Earthquake of August 1833, was from between 28° and 29° to 22° 

 North latitude, and from about 77° to 92° East longitude, embracing 

 accordingly 7° of latitude and 15° of longitude ; a superficial extent, 

 upwards of four times that of the British Isles, and about twice and a 

 half that of the kingdom of France !
