Mount Kilimanjaro, located inTanzania, is a famous stratovolcano composed of three distinct volcanic cones: Kibo, Mawenzi, and Shira. Among these, Kibo is the highest and is dormant with the last major eruption occurring several hundred thousand years ago. Mawenzi and Shira are extinct. Mount Me...

Hawaiian eruptions get their names from the Kilauea Volcano on the Big Island of Hawaii, which is famous for producing spectacular fire fountains. Two excellent examples of these are the 1969-1974 Mauna Ulu eruption on the volcano's flank, and the 1959 eruption of the Kilauea Iki Crater at ...
or blocks, depending on shape. During a cinder cone eruption, pyroclastic material that looks like cinder shoots up, then rains back down, building a small cone with steep sides. Eruptions are usually short-lived. Wizard Island in Crater Lake, Oregon, is an example of a cinder cone volcano...
In this eruption, clots of molten lava burst from the vent (summit) into the sky. It looks like fireworks, displaying luminous arcs or fire. It was observed during an eruption of the Iruzu Volcano in Costa Rica in 1965. Vulcanian eruption: ...
Effusive eruptions are the most common type of volcanic eruption. They are typically characterized by the outpouring of lava that flows down the sides of the volcano. Lava flows can be very fluid or very viscous, depending on the composition of the magma. ...
A caldera is a volcanic crater, usually more than 2km in diameter. They form when an explosive eruption destroys the cone and the magma chamber below is emptied. Without magma providing support below a caldera is formed when the sides of the volcano collapse. ...
What are the characteristics of a composite cone volcano? Composite cone volcanoes have steep slopes. This is due to their more explosive eruption style and more felsic, viscous lavas. They are also distinguished by their interior conduit system that brings the molten rock to the central crater ...
In a “Strombolian”-type eruption observed during the 1965 activity of Irazu Volcano in Costa Rica, huge clots of molten lava burst from the summit crater to form luminous arcs through the sky. Collecting on the flanks of the cone, lava clots combined to stream down the slopes in fiery ri...
