Do you know what caused it? LoisAs they say, That's an excellent question. I'll difer to the experts:
http://www.srh.noaa.gov/bmx/?n=outreach_microbursts What causes a Microburst? It all starts with the development of a thunderstorm and the water droplets/hailstones being suspended within the updraft. Sometimes an updraft is so strong it suspends large amounts of these droplets and hailstones in the upper portions of the thunderstorm. There are many factors that can lead to evaporational cooling (sinking air) and therefore weakening of the updraft. Once this occurs, it is no longer capable of holding the large core of rain/hail up in the thunderstorm. As a result, the core plummets to the ground. As it hits the ground it spreads out in all directions. The location in which the microburst first hits the ground experiences the highest winds and greatest damage.
Also there's a lot of good info (and pics) over here: http://thevane.gawker.com/explaining-microbursts-one-of-natures-most-dangerous-w-1643929336
