On February 29, 1960, a violent 14 second earthquake destroyed 80 percent of Agadir, killing over half its inhabitants. Today, this south Moroccan town, the Souss valley's only industrial town and port, is being rebuilt. To make the new Agadir safe for its planned 50,000 inhabitants, the Moroccans consulted Swiss and French town planners and other foreign architects and builders. Geologists advised a new site a mile to the south. A High Commission for Reconstruction was established and special earthquake resistant methods were officially approved. No building permission is given if even the smallest construction does not conform to the "Normer Agadir 1960." These norms define all construction requirements and stress the importance of avoiding unsafe building sites such as steep slopes, water-impregnated ground, sandy soil, or rubble filled soil. Rocky ground is considered best. The Normer Agadir 1960 insure that the new town will withstand an earthquake force of 8.5 on the Richter scale.
