Oki-Dogo volcano is a complex of shield volcanoes forming small islands north of the SW Honshu city of Matsue in the Japan Sea off the west coast of Japan. Most of the volcanic activity took place 800,000-300,000 years ago, but there has probably been activity during the past 10,000 years as well, producing basaltic lava flows and a cinder cone.
Dogo-onsen Hot Spring is Japan's oldest spa. It is said to have been in operation since about 3000 years ago.

Introduction to Plate Tectonics: The Earth's upper, rigid layer is broken into several plates which are in constant motion to one another. Most earthquakes and volcanoes occur as result of these plate boundaries.
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.
