inferno

A place or situation resembling Hell.

At each sudden explosion in the inferno below they sprang back from the brink [of the volcanic crater].

When Jurgis had first inspected the packing plants with Szedvilas, he […] found that each one of these lesser industries was a separate little inferno, in its way as horrible as the killing beds, the source and fountain of them all[, and t]he workers in each of them had their own peculiar diseases.

A large fire; a conflagration.

The inferno ripped through the forest, destroying anything in its path.

Blast after blast, fiery outbreak after fiery outbreak, like a flaming barrage from within,[…]most of Edison's grounds soon became an inferno. As though on an incendiary rampage, the fires systematically devoured the contents of Edison's headquarters and facilities.
