Morphology

ground + fire

The noun-noun compound 'ground fire' is directly compositional: combining 'ground' (earth/soil) with 'fire' yields a fire occurring in or on the ground. While the technical detail (smouldering in the humus layer) is specialised, a B1 learner who knows both words can readily infer the general meaning.

Etymology

The noun ground fire comes from the fire that burns slowly in the layer of rotting leaves and roots under the ground, so there are often no flames above. That's why it means 'a fire that burns below the surface' and is hard to see or put out.
