@RobinLacassin Fascinating.

You might also be interested in Maria Graham who described an 1822 earthquake in Chile and published her observations in Transactions of the Geological Society in 1824 and was used as a source by Charles Lyell in Principles of Geology.

great article. That watercolor is definitely easier to interpret than the photo.
