This dormant stratovolcano in Papua New Guinea suddenly exploded in 1951. Nuees ardentes
(glowing avalanches) shot down the mountain at 100 km per hour, devastated over 200
km2, and killed about 3,000 people. Temperatures of the cloud were so high that the
deposits were still hot two years later. Following the explosive eruption, a 500-meter-high
lava dome grew in the explosion crater until 1956. |
