1868年厄瓜多尔瓜亚基尔暨哥伦比亚圣巴勃罗地震

The northern Andes were struck in 1868 by a magnitude 7.7 earthquake that damaged cities across Ecuador and southern Colombia, including Ibarra, and is associated with about 70,000 deaths. Shaking reached Mercalli intensity X. The rupture lay along the Nazca–South American subduction boundary, where the descending oceanic plate drives frequent great earthquakes beneath the Andean margin. Ibarra was so thoroughly destroyed that survivors abandoned the site for years before rebuilding. The event is among the deadliest in the seismic history of the equatorial Andes and remains a reference point for hazard assessment in the region.
