Arica, a seaport town of Peru, in a province of the same name, department of Moquegua, in lat. 18° 26' S., lon. 70° 24' W., 640 m. S. E. of Lima, and 30 m. S. of Tacna, with which it is connected by railroad. It has been the theatre of many destructive earthquakes, one of the worst of which occurred Aug. 13 and 14, 1868, involving the loss of 500 lives and $12,000,000 worth of property. Not a building was left uninjured. The shocks were followed by a tidal wave in which the United States storeship Fre-donia was wrecked with the loss of all hands, and the United States steamer Wateree and oilier vessels were carried ashore and stranded. The fortified island of Alacran, which defends me port of Arica, was submerged three times, all the garrison perishing. The first wave, which rose to about 40 feet, was succeeded by three or four others of less height. The shocks occurred on the first day every quarter of an hour, and on the second day every hour. Among the curious effects of the earthquake in the vicinity of Arica was the opening of the earth, and the disclosure of a large number of mummies, which had been buried in the sand in a sitting posture, facing the sea, in a ceme-etery covering a large area.
