The Volcano Adventure Guide: Excellent information and background for anyone wishing to visit active volcanoes safely and enjoyably. The book presents guidelines to visiting 42 different volcanoes around the world.
Cerro del Azufre ("sulphur peak") volcano is a large andesitic stratovolcano in northern Chile 20 km from the border with Bolivia. It is the largest and youngest volcanic center of a 50-km-long, NW-SE-trending chain of volcanoes south of Salar de Ascotán.
The volcano has 2 summits, the northern peak forming the summit and the lower southern peak (5700 m) belonging to an earlier stratovolcano, which extends towards the extinct Cerro Aguilucho volcano.
It is uncertain whether the volcano has erupted in the past 10,000 years. There are a number of fresh-looking lava domes and craters, but in this region erosion and weathering are so inefficient that such craters can look young, but are actually hundreds of thousands of years old.
Note: there is a volcano with a similar name - "Cordon del Azufre" in northern Chile.
Intraplate volcanism: A third tectonic setting where volcanism occurs is believed to be the result of mantle plumes and not directly related to plate boundaries. So called hot spot volcanoes fall into this category.
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.
