Book Description
This book describes the interrelationship between the spectacular geology of an area of East Africa that includes a branch of the rift valley, as well as giant freestanding ice-capped mountains and extraordinarily toxic, alkaline lakes, and some of the greatest concentrations of wildlife on Earth. It suggests that geological processes that have shaped the iconic landforms, including active volcanoes, may also be responsible for the unusually diverse speciation which characterises the region. Moreover, it is not a coincidence that important palaeoanthropological discoveries have been unearthed in the region. National parks and conservation areas have tremendous potential for geotourism and the book assists both tour guides and visitors in this regard. In addition, the book may provide a better understanding to management of the importance of geology for sustaining wildlife.

Book Description
Despite being a large capital city in Africa in terms of size and its regional role, Nairobi is an unrecognised entity. For the majority of its inhabitants, the capital of Kenya is a transit point rather than a dwelling place. Since its origins, Nairobi has been a city of migrants, more predisposed to their rural roots than to their current city status. It is a non-conforming town, which conceals its urbanity more than it claims it, and whose identity remains evasive. Nairobi presents itself as a mosaic of residential areas which bring to mind the citys history. The racial segregation that stratified the development of the colonial city has today disappeared, but it has given way to a form of social segregation. One must, therefore, not seek a unique identity in Nairobi, but rather, several identitiesthose of different communities that comprise the city and whose dynamics are seen at village and residential estate level. However, Nairobi is also a city that is contradictory. This East African capital city is often associated with slums and crime, and their increase and growth stigmatises the failure of urban policies. Therefore, it is at these cracks and fringes of the city that we should seek out the identities and dynamics that have shaped the city for a century. Nairobi is a fragmented city that can be understood in steps. The 13 contributory articles in Nairobi Today thus reveal the city. This multidisciplinary collective work invites us to gain entry into certain areas of the city, to visit its communities and to familiarise ourselves with its formal and informal institutions. This is a requirement in order to fully understand what makes Nairobi what it is today.

Book Description
The East African Rift System (EARS) and by extension the Davie Ridge, which is considered as the seaward extension of eastern branch (Kenya Rift Valley) of the East African Rift Valley (), are characterized by divergence whose maximum rate is estimated to be about 7mm/year (). This rate of divergence is somewhat much slower than that found at most active mid-ocean ridges or even the convergence of India–Burma plates or that between the Australian and Sunda plates (). Despite this slow rate of divergence, the East African Rift Valley and the Davie Ridge are characterized by frequent seismicity with large and shallow earthquakes occurring occasionally. Seismic reflection, gravity, and magnetic data from offshore East Africa allow the Davie Fracture Zone to be traced from 11oS to its intersection with the Kenyan coast at 2oS, constraining the relative motion of Madagascar and Africa (). Further, numerous faults and fractures probably associated with the Davie Fracture have been mapped using recent gravity and magnetic data between latitudes 2o21′S and 3o03′S and longitudes 40o08′E and 40o45′E by . Seasat-derived free-air gravity anomalies and slope/rise positive magnetic anomalies observed in shipboard data help to locate the continent–ocean boundaries (COB) off the shore of East Africa and Madagascar. Furthermore, the EARS, and precisely the Kenya Rift Valley, is characterized by ~3-km-thick sediments and normal-faulting mechanism. Deformation has been active along the Kenya Rift Valley as evidenced by high seismic activity. Surface deformation studies from SAR interferometry in the southern sector of the Kenya Rift Valley in Magadi show that it is characterized by 14cm of deformation over 10-km-long stretches (). If the Davie Ridge is an extension of the East African Rift Valley, we cannot rule out the occurrence of tsunami-generating earthquakes, which are bound to have devastating consequences on the eastern coast of Africa. Earthquakes as deep as 40km have been recorded below Davie Ridge (). However, evaluation of recent seismic data shows that magnitude 6.0–7.2 earthquakes at relatively shallow depths of 10–30km are a common occurrence along the Kenya Rift Valley and the Davie Ridge in the Mozambique Channel. The focal mechanism of these earthquakes supports what has previously been proposed that the Davie Ridge is a southward extension of the eastern arm of the EARS. The earthquake focal mechanism indicates that the Davie Ridge is characterized by predominantly normal faulting with occasional oblique faulting. Consequently, Kenya and generally the East African coast are prone to both seismic hazards on land and tsunami-generating earthquakes. This chapter begins with general overview of the seismicity in Kenya from the 1900s to the present. Seismicity in Kenya up to 1963 is mainly based on macroseismic data while that from 1963 to the present is based on data from instrumental recordings. In the past, a number of microseismic and seismicity studies in Kenya have previously been undertaken and the results from these studies are rather disjointed. In this chapter, we have made an attempt to merge all the existing results into one database from which the general seismicity, and subsequently seismic hazard in Kenya has been evaluated. The main goal of this chapter is to bring into focus the area(s) in Kenya more prone to seismic hazards either due to ground shaking occasioned by an earthquake or due to tsunami as a result of earthquakes occurring along the Davie Ridge.
