The 1868 Ecuador earthquakes occurred at 19:30 UTC on August 15 and 06:30 UTC on 16 August 1868. They caused severe damage in the northeastern part of Ecuador and in southwestern Colombia. They had an estimated magnitude of 6.3 and 6.7[1] and together caused up to 70,000 casualties.[2] The earthquake of 15 August occurred near El Ángel, Carchi Province, close to the border with Colombia, while that of August 16 occurred near Ibarra in Imbabura Province.[1] Reports of these earthquakes are often confused with the effects of the earthquake of 13 August at Arica.[2]
