Rift Valley has a history of tectonic and volcanic activities. Some of its parts such as Nakuru, is highly vulnerable to sinking down of land from natural earth movemen such as landslides, earthquakes and related disasters.
Experts point out that a large part of Nakuru has cracks and fissures that pose danger to tall buildings and that soil in the region and its environs is unconsolidated as a result of past eruptions that occurred at the Menengai Crater some years back.
During heavy rains and flush floods, the fissures, due to unconsolidated deposits accompanied by slumping and flushing of material deep down, produce holes and funnel shaped depressions, which cannot hold heavy weights.
Building and Construction Standards and Codes (BCSC) developed by the defunct Municipal Council of Nakuru insisted on development of low storey buildings, less than four floors but this is currently being disregarded.
A craving to make best use of space and realize quick returns have surpassed fears that should a tremor occur, these buildings would come tumbling down like a pack of cards. Nakuru with buildings exceeding four storeys is a catastrophe in making as the County sits on unstable geological zones and experiences subtle volcanic faulting.
Experts also hold an opinion that in the Eastern Africa region, Somalia and half of Ethiopia, Kenya and Tanzania will be cut off from the rest of Africa to create a new continent known as the Somali Plate in about 50 million years time.
