Dar es Salaam (Tanzania, 88 km NW of epicenter) : Now that I think back, I was up working at that time and I felt as if my head was shaking and I could not control it. I feel dizzy sometimes and I had attributed it to that, but never while sitting so I was a bit worried. I live on the 10th floor and the effect must have been magnified by the height!!!
