Event narrative

The earthquake occurred at 7:47 p.m. local time on Sunday March 3rd 1985. The epicenter was located approximately 80km southwest of Viña del Mar and at an estimated focal depth of 33 km. Two separate events have been identified. The first, having a P-wave magnitude mb=5,2, was followed ten seconds later by a main event having a surface wave magnitude Ms=7,8 an P-Wave mb=6,9. Modified Mercalli Intensities were as high as VIII in the epicentral region, including portions of Viña del Mar. The earthquake resulted in extensive damage and casualities in the central region of Chile. Approximately 66.000 homes were destroyed and another 127.000 were damaged throughout the region. During the earthquake, approximately 150 people were killed, and another 2.000 were injured. Damage was not uniform for all construction types. Most adobe buildings in the epicentral region experienced some damage, with many in a state of partial or total collapse. Wood residential construction generally performed well, as did the majority of the low-rise masonry strucctures constructed with reinforced concrete confining elements. Steel structures, which are not common, generally did not sustain notable damage.
