A well-engineered high rise apartment and two-story building in Talca, Chile suffered no evident damage, though much of the city was affected by the M 8.8 earthquake on Feb. 27, 2010. Many buildings in this city were constructed with adobe or masonry and suffered major collapse.

A cathedral in the central square of Chillán, Chile replaces the ancient cathedral that collapsed during the strong earthquake of 1939. This modern structure was constructed with earthquake resistance as the primary consideration. The only damage caused by the M 8.8 earthquake on Feb. 27, 2010 was broken windows.

This masonry office building in the downtown area of Concepcion, Chile collapsed as a result of the M 8.8 earthquake on Feb. 27, 2010. The construction of this building predates the establishment of strict building codes in Chile, put in place following the devastating earthquake of 1960.

The tsunami generated by the M 8.8 earthquake carried many boats onto land - in some cases hundreds of meters inland. The tsunami wave height at this location in Concepcion Harbor (Talcahuano), Chile was about 4-5 meters (12-15 feet).

A house and a car were destroyed by a tsunami in the coastal city of Dichato, Chile, located about 15 km north of Concepcion, Chile. The tsunami height was about 10 meters (32 feet). Several hundred homes were destroyed in this city as a result of the M 8.8 earthquake on Feb. 27, 2010

Two school teachers stand outside a neighbor's destroyed adobe home in Cauquenes, Chile following the M 8.8 earthquake on Feb. 27, 2010. Reconstruction in this ancient city will be based on reinforced concrete rather than highly vulnerable adobe.

The interior of this masonry-built hospital in Cauquenes, Chile had severe fracturing and partially collapsed interior walls following the M 8.8 earthquake on Feb. 27, 2010. This building will be torn down and replaced with a reinforced concrete building.
