A Practical and Effective Solution to Earthquake (EQ) Catastrophe

Abstract

About 50-year direct observation indicated that any civil structure founded in/on rock do not get damage from earthquakes without tsunami effect. The main reason behind this is that the modulus of elasticity of saturated rocks is million times greater than that of saturated soil units. Furthermore, all saturated soil units are susceptible to liquefaction at varying degrees. Based on the past observations, none of the structures founded in/on rocky ground, has been affected from the recent destructive earthquakes studied by the authors in/and abroad. The studied earthquake cases highlighted again that the civil structures in/on rocky grounds, even adjacent to the epicenter, have not been affected from shaking of destructive earthquakes. In Turkey, the land needed for housing is one hundredth of the country. However, 57% is proper for housing. The remaining 43% consists mainly of forest, restricted zones, rugged terrains, and soil land which bears essentially plains and very locally landslides. Thus, earthquake disasters could be alleviated by implementing practical land use planning.
