The Project area has often suffered from disaster caused by lahar because of topographical, geological and socio-economic situations. In recent years the most serious disaster was caused on May 14, 1981 by the lahar which destroyed the Leces Dike and inflicted serious damage on the sabo dams, dikes, irrigation intakes and so on.
The rapid growth of geothermal electrical generation in recent years has been accompanied by rapid growth in our knowledge of the behavior of reservoirs in their natural and exploited states. Good textbooks and literature surveys exist both for the earth sciences and for surface plant engineering.
