Oshima as an island stratovolcano with a large caldera on its summit. Stratovolcanoes are conical volcanoes built up by many layers of hardened lava and volcanic ash, with steep profiles and periodic eruptions.Know More
The main stratovolcano cone of the island has a base composed of basalt lava and pyroclastic rocks. When an erupting volcano empties a shallow magma chamber, the volcanic formation can collapse into the voided reservoir and produce a cauldron-like depression.
Based on geological evidence, it is estimated that Oshima has erupted over 100 times since 8450 B.C. As of 2014, the last eruption was in 1990 at the summit of Mihara-yama.Learn More
Shield volcanoes produce eruptions with lava that pours over the top of the summit and features low-density magma. There is a low quantity of ash during the eruption.Full Answer >

Mt. Kilimanjaro is a stratovolcano. A stratovolcano, also called a composite volcano, is tall and steep and has many layers of lava, tephra (what falls back through the air after an eruption) and ash. This is one of the most typical volcanoes.Full Answer >
Paricutin is considered to be a scoria, or cinder, cone volcano. It stands at a height of 9,186 feet above sea level and has a lava field that covers an area of 10 square miles around it. As of 2014, it is the youngest Western Hemisphere-based volcano.Full Answer >
