Geologists hais tias tom qab ob peb lab xyoo, African teb chaws yuav faib ua ob feem, nrog rau cov Somali tectonic phaj, uas txav deb ntawm lub Nubian los ntawm 6-7 millimeters ib xyoo, thiab nyob rau hauv sab qab teb - ntawm tus nqi ntawm 2.5 centimeters. ib xyoo.

Qhov kev txhaum uas tau tsim thaum pib lub lim tiam dhau los cuam tshuam rau txoj kev tsis khoom Mai Mahyu-Narok. Tsoomfwv Kenyan tau hais kom lub tsev kawm ntawv muaj cov pob zeb thiab cov cement kom cov tsheb tuaj yeem txuas ntxiv mus.
