Women were preparing food. Men were walking between gardens. The mountain that rose to the south was called Sumburipa in the Orokaiva language, and nobody thought of it as dangerous. It was just there, forested, quiet, the way it had been for all of living memory. At 10:40 a.m. on 21 January 1951, a black plume rose 50,000 feet into the tropical sky. Within a minute or two, a pyroclastic flow hot enough to melt plastic lampshades but not to ignite wood, moving at roughly seventy kilometres per hour, surged down the northern flank and erased the village. Up to 94 per cent of Sangara's people died. In total, 2,942 people were killed, most of them Orokaiva. The mountain the newspapers would call Mount Lamington had declared itself a volcano for the first time in recorded history.

That sentence is a bit of technical volcanology that conceals a physical event so extreme it borders on incomprehensible. When the dense ash cloud over the summit could no longer hold itself up, it fell, hot, dense, heavy with rock fragments, and sp...

Within a week, taro plants were sprouting in villages on the edge of the devastation. Yam, sweet potato and banana followed. By early 195...
