Event narrative

On January 25th, 1999 at 1:19 in the afternoon the city of Armenia, Colombia, suffered the devastation of an earthquake of magnitude 6.1 (Mw) with a focal depth of 17 km. the earthquake and a series of aftershocks were felt through 5 departments in western Colombia (Caldas, Quindio, Risaralda, Tolima and Valle del Cauca). This area has a well known high seismic hazard, due to the triple junction that occurs at the northwest corner of the South American Plate where the Nazca, Cocos, and Pacific plates converge. 1185 people were killed due to the ground shaking while 8523 were injured. About 60% of the existent structures in Armenia collapsed. Most of these buildings that collapsed were old and poorly constructed, or were built on poor soil such as old landfill sites or steep slopes. The newer structures, for the most part, survived intact due to safety measures being established in 1984 after the Popayan earthquake in 1983. The main economic activity of the region, the colombian coffee industry was heavily affected. About 8000 coffee farms were completely or partially destroyed. Losses are estimated in about US$2000 mill.
