The Regional Municipality of Wood Buffalo (around and including Fort McMurray) site reported the following as an approximate overview of the damage sustained to date (May 04, 2016):
There are firefighters, aircraft and heavy equipment working on the wildfire and more resources are on their way however high temperatures, low humidity and strong winds continue to fuel the fire. The image shows the area almost completely obliterated by the clouds of smoke rising from the fire.
The smoke released by any type of fire (forest, brush, crop, structure, tires, waste or wood burning) is a mixture of particles and chemicals produced by incomplete burning of carbon-containing materials. All smoke contains carbon monoxide, carbon dioxide and particulate matter (PM or soot). Smoke can contain many different chemicals, including aldehydes, acid gases, sulfur dioxide, nitrogen oxides, polycyclic aromatic hydrocarbons (PAHs), benzene, toluene, styrene, metals and dioxins.
The type and amount of particles and chemicals in smoke varies depending on what is burning, how much oxygen is available, and the burn temperature. Exposure to high levels of smoke should be avoided. Individuals are advised to limit their physical exertion if exposure to high levels of smoke cannot be avoided. Individuals with cardiovascular or respiratory conditions (e.g., asthma), fetuses, infants, young children, and the elderly may be more vulnerable to the health effects of smoke exposure.

今回取り上げる単語は、"obliterate"です。文脈的に「(煙などに)覆われている」という意味を想像しました。
まず、LDOCEで調べてみると、
1. "to destroy something completely so that nothing remains"
2."to remove a thought, feeling, or memory from someone's mind"
3."to cover something completely so that it cannot be seen"
『ジーニアス英和辞典』(大修館)第4版では、1.「(痕跡、記憶など)を(完全に)消す」2.「…を完全に破壊する、(…から)取り除く、(光景、音を)見えなくする(聞こえなくする)、遮蔽する」とありました。
今回の場合は、2番目の意味で使われています。「火事現場はほぼ完全に煙で覆われている」という悲惨な状況が伺えます。
