earthquake in hk

A minor earthquake was recorded by the Hong Kong
Observatory at 2:42 p.m. today (Friday, 19 November 2010).

The epicentre was initially determined to be in the
vicinity of Deep Bay (22.5N, 113.9E) about 35 kilometres
northwest of the Hong Kong Observatory. The magnitude was
estimated to be 2.8 on the Richter Scale.

How did it feel?
Just a few quick shakes whilst sitting by the computer in the office.
But shaky enough to make me wonder - earthquake - no... can't have been and then I just got on with the day...
