My dear Caroline,
[…] We are now on our road from Concepciòn.— The papers will have told you about the great Earthquake of the 20th of February.— I suppose it certainly is the worst ever experienced in Chili.— It is no use attempting to describe the ruins—it is the most awful spectacle I ever beheld.— The town of Concepcion is now nothing more than piles & lines of bricks, tiles & timbers—it is absolutely true there is not one house left habitable; some little hovels built of sticks & reeds in the outskirts of the town have not been shaken down & these now are hired by the richest people. The force of the shock must have been immense, the ground is traversed by rents, the solid rocks are shivered, solid buttresses 6–10 feet thick are broken into fragments like so much biscuit.— How fortunate it happened at the time of day when many are out of their houses & all active: if the town had been over thrown in the night, very few would have escaped to tell the tale. We were at Valdivia at the time the shock there was considered very violent, but did no damage owing to the houses being built of wood.— I am very glad we happened to call at Concepcion so shortly afterwards: it is one of the three most interesting spectacles I have beheld since leaving England—A Fuegian savage.—Tropical Vegetation—& the ruins of Concepcion— It is indeed most wonderful to witness such desolation produced in three minutes of time.

Watching this I couldn't help recalling how, at the end of his Journal of Researches (a.k.a. The Voyage of the Beagle), Darwin wrote,'Among the other most remarkable spectacles which we have beheld, may be ranked the stars of the southern hemisphere—the water-spout—the glacier leading its blue stream of ice in a bold precipice overhanging the sea—a lagoon island raised by the coral-forming polypi—an active volcano—and the overwhelming effects of a violent earthquake. The three latter phenomena, perhaps, possess for me a peculiar interest, from their intimate connexion with the geological structure of the world. The earthquake must however, be to every one a most impressive event : the earth, considered from our earliest childhood as the type of solidity, has oscillated like a thin crust beneath our feet; and in seeing the most beautiful and laboured works of man in a moment overthrown, we feel the insignificance of his boasted power.'That last thought is especially poignant now that we are seeing the most beautiful and laboured works of nature in a moment overthrown.... by us.
