Pagan VulkanPagan volcano consists of 2 stratovolcanoes (North and South Pagan) connected by a narrow isthmus and forms the largest and one of the most active of the Mariana Islands. It is located 173 nautical miles north of Saipan.
Nearly all historical eruptions of Pagan, which were recorded since the 17th century, were from North Pagan volcano. The largest historic eruption was in 1981 and prompted the evacuation of the sparsely populated island.
Beschreibung: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.
