On the sides of a ravine between that town and rorio^ I saw

Torrents of rain swelled the Magdalena, sweeping along vast 

 quantities of mud and other substances, which emitted a 

 sulphurous vapour and destroyed the fish. Popayan, which 

 is distant 200 geographical miles SSW. of Bogota, suffered 

 reatly. Wide crevices appeared in the road of Guanacas, 

 leaving no doubt that the whole of the Cordilleras sustained 

 a powerful shock. Other fissures opened near Costa, in the 

 plains of Bogota, into which the river Tunza immediately 

 began to flow.f Extraordinary rains accompanied the shocks 

 before mentioned ; and two volcanos are said to have been in 

 eruption in the mountain-chain nearest to Bogota.

November 19, 1822, the coast of Chih 



was visited by a most destructive earthquake. The shock 

 was felt simultaneously throughout a space of 1,200 miles 

 from north to south. St. Jago, Valparaiso, and some other 

 places, were greatly injured. When the district round

 of the sea, says Mrs. Graham, remained bare and dry at 

 high water, ' with beds of oysters, mussels, and other shells 

 adhering to the rocks on which they grew, the fish being all 

 dead, and exhaling most offensive efl9.uvia.§
