Twin Towers' Dust Clouds
Photographic Evidence of Dust Clouds From the Twin Towers' Destruction
The dust clouds that issued from the Towers' explosive collapses were unlike anything seen in the history of man-made structures. Even conventional explosive demolitions of large buildings produced far less dust. Their appearance and rate of travel resembled the pyroclastic flows of volcanoes.
This page lists photographs which show the dust clouds that continued to expand after the waves of destruction that demolished the towers reached the ground. Photographs listed on the collapses page also show a great deal of dust, whose production started within the first second of each collapse.
