earth tremors

shook Nairobi last night. One set around midnight - dramatic enough to make my parents leap out of bed. Another smaller rumble just before 3am.

Apparently, they were the ripple effect of an earthquake near Lake Tanganyika. 5.4 on the Richter scale, which falls in the not-too-serious zone. But it's still unnerving to feel the earth shift under you. To realize it's actually not a solid constant.
