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.
Myoko volcano is a steep basaltic-to-dacitic stratovolcano north of Nagano City that overlooks the popular resort of Lake Nojiri below its SE flank.
Myoko's summit is formed by a lava dome filling most of a 3-km-wide caldera which is widely breached to the east.
No historical eruptions are known at Myoko, but there is constant solfataric activity between the dome and the south caldera wall at a place where sulfur was once mined.
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.
