Mayon volcano photos
: Mayon on Luzon Island, towering above Legazpi city is famous for being one of the most perfectly symmetrical stratovolcanoes in the world. It is also one of the most active and most dangerous volcanoes (not only) in the Philippines.
: In the afternoon of 17 Oct, a particularly violent explosion occurred at Anak Krakatau, blasting away a portion of the southern crater rim. A similar event might have been the final trigger for the catastrophic landslide that let the cone collapse and cause a devastating tsunami on 22 Dec 2018.
Sakurajima volcano photos
: One of the world's most active volcanoes, Sakurajima on Japan's Kyushu Island is famous for its frequent vulcanian explosions, often accompanied by eruption lightning.
: We have published several volcano calendars over the years: usually, we use photos taken by us or our participants during our recent volcano tours and expeditions. A perfect gift if you're a fan of volcanoes!
