At 1:19 pm on Monday, January 25, 1999 a 5.9 ML struck the western part
of Colombia.  The epicenter was located 17km south of Armenia and 48km
south of Pereira, causing more than 1,000 deaths and thousands of
injuries.  Within a matter of seconds entire city blocks were destroyed
and thousands left homeless.   Much of the damage resulted from poor
construction and large amplifications of ground motions due to soft soil
conditions.  Numerous landslides disrupted roads and impeded emergency
response.  The EERI Team, lead by Eduardo Fierro, traveled to Colombia
one week after the earthquake, where they met with members of the local
science and engineering communities and gained access to the heavily
damaged areas. Their observations focus on the nature and extent of
damage and will cover the following topics:

· Geologic and geotechnical considerations
· Ground motion aspects
· Engineered and nonengineered structures
· Lifelines
· Highway and bridge damage
· Emergency response and recovery challenges
· Public health and societal impacts
