Abstract
At 8:25:13 a.m. local time (06:25:13 GMT), May 12, 1971, an earthquake reported in the Richter Magnitude range 5.5-6.3 struck the area of Burdur, a modern city of 33,000 people in southwestern Turkey. Fifty-seven persons were killed, and property damage estimated at $25 million resulted. Just ten days later, at 6:43:59 p.m. local time (16:43:59 GMT), another earthquake, reported in the Magnitude range 6.0-6.9, struck the area of Bingol, a city of 17,000 population, 900 km ENE of Burdur. Here 755 persons were killed, and property damage was estimated at $28 million. These earthquakes, together with the Gediz earthquake (March 28, 1970, Magnitude range 7.0-7.5), in the span of a little more than one year, killed some 1,900 persons in this nation of 35.6 million, and cost in damages and relief efforts at least 5% of the annual national government budget of some $2 billion. This report presents observations and analyses of earthquake damage in Turkey, and makes recommendations for structural improvements and for better dissemination and enforcement of building design and construction regulations.
