In 1985, the small Indonesian island of Sangeang Api (for scale, the island is 13 km wide) off the northeast coast of Sumbawa began to erupt. Within a month, the 1250 inhabitants had evacuated to Sumbawa. The eruption lasted until 1988. The lava and pyroclastic flows--the wide channel running west from the summit--are still easily traced on this image taken last week by Space Shuttle astronauts (STS-112) . Today, the island's summit crater (1949 m) produces intermittent steam clouds.
