Crack on the outskirts of Naivasha town in Nakuru County, Kenya.
A month after a huge crack was reported in Kenya's Rift Valley, another two-kilometre fault line has cracked open on Monday on the outskirts of Naivasha town in Nakuru County where farms have been swallowed.

Local media reports say at least 16 families have moved to safe grounds as several acres of crops were destroyed by the crack that was filled with water believed to be from rains in other parts of the country, reports Daily Nation.

"The heavy rains pounding this region have contributed in a way to the fault line ... It's a 20-foot deep fault line that runs across several agricultural farms. The families were asked to leave primarily for their safety," said Naivasha assistant county commissioner Joseph Opondo on Tuesday.

He added that a team of engineers and experts are assessing the situation as roads and a major river have also been affected.

The cracks started last month after a huge tear that is more than 50 feet deep and more than 50 feet wide in Narok County believed to have been caused by heavy rains and seismic activities.

Geologists say in about 50 million years, the African continent will split into two with the Somali tectonic plate which covers the Great Rift Valley - running from the Horn of Africa to Mozambique - separating itself from the Nubian Plate (African Plate).

Kenyan geologist David Ahede told local media that he believes the origin of the movements is a shield volcano called Suswa that lies at the base of the Great Rift Valley with a history of tectonic and volcanic activity.

He added that the earth movements have resulted in weaknesses and the weak zones form fault lines and fissures which are normally filled by volcanic ash, most likely from the nearby Mt Longonot.
