Popayan Colombia 1983 (ERNAL)
An earthquake of magnitude 5.6 (Mw) struck the city of Popayan, located in southwestern Colombia, at 8:12 in the morning (local time) the 31st of March 1983 during Easter celebrations. The earthquake was felt in 11 surrounding municipalities of the department of Cauca and it had a focal depth of 30.1 km. The historic city center was destroyed by the ground shaking and most of the colonial buildings constructed in adobe or “tapia pisada” (compacted earth held in place with a temporary form) were severely damaged. Approximately 2500 dwellings were completely destroyed and more than 1500 people were injured. Since the earthquake occurred while services were being held for catholic Holy Friday celebrations, and part of the Cathedral collapsed, 25% of all the deaths caused by the earthquake occurred there. About 250 people were killed and 1,500 injured. Losses were of the order of US$400 million.
This number is not stated explicitly, but rather taken from the fact that there are no deaths from other factors.
