A mini quake shook downtown Nairobi this afternoon. Buildings swayed gently from side to side for about fifteen-seconds, with calendars flying off the walls. No damage really, just to people’s psyches. They hurried downstairs from twenty floors up, with memories of the 1998 bomb blast at the back of their minds and stayed down until they ascertained that it was just a tremor. Most offices closed early at 4 p.m.
