Seismicity of the Nairobi city area, its geotechnical implications and mitigation measures

Abstract

<正>This paper is an attempt to determine how vulnerable the city of Nairobi is to earthquake attack and the potential disaster sites within it and its environs,how this affects the structural integrity of the its construction works and the sustainable way forward.Nairobi sits close to the eastern flanks of the Great Rift Valley and recent revelations that indicate the valley may be expanding at a rate of 2-3 mm per year due to tensional forces in the crust(Waithaka, 2001).The high heat flow beneath the crust is represented by the geothermal activities at Olkaria,
