Asked in Science, Oil Refineries
Why do the worst fires occur at oil refineries?
It may be an unsupportable assumption that the worst fires occur at oil refineries. Oil refinery fires are usually extinguished quickly and are usually well contained. It all depends how you define 'worst'. The most difficult to stop fires tend to be fires in forested lands. The most expensive fires tend to be large commercial buildings. Fires with the highest human death rates tend to be in dense informal urban settlements - so called slums. The most polluting fires tend to be associated with gas flares and well fires in oilfields.

When did the Victorian fires stop?
The fires have not completely stopped, but the worst of them are over. As of 12 March 2009, authorities in Victoria announced that the last of the worst bushfires which caused the most death and devastation were under control. However, there are many minor fires that, without significant rain, are expected to continue to burn until the Australian wimter, which begins in June. Conditions remain very dry, and lightning strikes have caused more fires, but these have been easily contained.
Asked in Australia, Australia Natural Disasters
What are the essential features of bushfires in Australia?
An essential feature is dry undergrowth which provides the fuel for the bushfire. Bushfires might start low, but they quickly spread and grow, especially uphill. For every ten degrees of a slope's gradient, the fire speed doubles. The worst bushfires in Australia are crown fires. These are enormously tall fires, which are fuelled by the eucalyptus leaves in the tree tops, generating incredible heat which often causes the tops of the trees to explode.
