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.
Towada volcano is a collapsed large stratovolcano with a 11 km wide dramatic caldera in northern Honshu, Japan. The caldera is occupied by Lake Towada, Japan's largest caldera lake.
The caldera formed during repeated collapse during 6 major eruptions between 53,000 and 13,000 years ago. A new cone grew within the caldera afterwards and collapsed as well, leaving the smaller 2 km wide Nakanoumi caldera nested inside. The SW and NE rims of Nakanoumi form spectacular peninsulas inside Lake Towada.
The only historic eruption of Towada volcano began on 17 August 915 AD from Ogura-yama lava dome near the Goshikiiwa cone on the NE rim of Nakanoumi caldera wall. The eruptions produced widespread ashfalls and pyroclastic flows.
The volcano belongs to Towada-Hachimantai National Park on the border between Aomori and Akita prefectures.
Fuego volcano photos: One of Central America's most active volcanoes, Fuego in Guatemala is in near-permanent explosive eruption with intermittent phases of increasing activity that generate lava fountains, lava flows and pyroclastic flows.
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.
