Background

Both North and South Pagan stratovolcanoes were constructed within calderas, 7 and 4 km in diameter, respectively. The 570-m-high Mount Pagan at the NE end of the island rises above the flat floor of the northern caldera, which may have formed less than 1000 years ago.
South Pagan is a 548-m-high stratovolcano with an elongated summit containing 4 distinct craters.
