A Red Crater in a Tropical Ash Plain

A Red Crater in a Tropical Ash Plain is an original illustration set in Mount Yasur, Tanna, Vanuatu. It lies in the tropics, where the climate is tropical rainforest — hot and wet all year.

A low active cone rises from a wide gray-black ash plain, with a restrained red glow visible inside its open crater. At the edge of the barren ground, tropical rainforest forms a dark wall whose outer crowns and gardens sag beneath fresh ash.

Why is an active ash-black crater surrounded so closely by damaged tropical rainforest?

Yasur's long-lived Strombolian activity repeatedly ejects incandescent fragments, gas, and ash from a small summit crater. Trade winds carry ash and acidic fallout across nearby ground, keeping the cone and downwind plain nearly bare while damaging vegetation and crops at the forest margin. The sharp meeting of active red crater, black ash, persistent plume, and ash-pressed tropical growth identifies a frequently erupting island-arc volcano in Vanuatu.
