In 1962, Guam was devastated by Super Typhoon Karen. In 1962, the destruction appeared catastrophic mainly because most of the buildings, facilities and structures were either constructed poorly or were constructed of wooden and tin materials. The reconstruction efforts severely tested the resiliency of the government of Guam. Restoration of critical services, such as electricity, water and sewer, and telephone took weeks. The government of Guam, learning from past experience, was able to restore vital utilities within a very short time.
Tremendous concerns exist with respect to the water and sanitary systems.
Major flooding in all low lying areas has resulted in up to 3,000 people being housed in shelters following the first day of the storm. Virtually all hotels sustained damage. Several schools have sustained major to serious damage. Damage to the airport and navigation lanes is extensive. Large boulders, coral and debris have been deposited in the harbor, causing hazards to navigation.
