CHAPTER III.
CONDITIONS OF EARTHQUAKE ACTION UPON ARCHITECTURAL STRUCTURES.
The effects produced by precisely the same shock, acting upon buildings differing in position, construction, material, &c., are so great, that it will be necessary to treat somewhat in detail of the conditions of earthquake action upon architectural structures; for without a thorough understanding of these, one is almost certain to be led astray by the strange, and often, at first sight, perplexing phenomena of destruction observable.
Throughout the kingdom of Naples, the edifices of cities, towns, and rural places present very uniform and striking characteristics, though varying much in dignity and size, &c.
