Considered a dormant volcano, it is the highest point of the Philippines. Mount Makiling in Laguna. Mount Banahaw in Quezon is one of the active volcanoes in the Philippines. Its 1730 eruption caused a debris avalanche and crater lake collapse which flooded Sariaya, Quezon.
stratovolcano, volcanic landform characterized by a conical shape formed by layers of volcanic material deposited during successive volcanic eruptions. Stratovolcanoes tend to slope gently at the base but rise quickly near the summit to form tall mountain peaks.
A stratovolcano or composite volcano is a dramatic volcano with a steep profile, layered composition, and explosive eruption. This type of volcano dominates the landscape and affects nearby populations and even the global climate.
Two examples of stratovolcanoes famous for catastrophic eruptions are Krakatoa in Indonesia, which erupted in 1883 claiming 36,000 lives. [8] Mount Vesuvius in Italy erupted in 79 A.D and killed an estimated 2,000 people. [9]
Examples of strato volcanoes include Mt. St. Helens, Mt. Rainier, Pinatubo, Mt. Fuji, Merapi, Galeras, Cotopaxi, and super plenty others. Although they are not as explosive as large silicic caldera complexes, strato volcanoes have caused by far the most casualties of any type of volcano. This is for many reasons.
What are Stratovolcanoes? Stratovolcanoes, also called composite volcanoes, are typically steep-sided, symmetrical cones built of alternating layers of lava flows, volcanic ash, and other eruptive products (see animation courtesy of Exploring the Environment).
Stratovolcanoes such as Mayon Volcano in the Philippines, Mount Momotombo in Nicaragua, and Ol Doinyo Lengai in Tanzania are steep cones built by both pyroclastic and lava-flow eruptions.
Composite volcanoes usually erupt a range of compositions from basalt to rhyolite, but intermediate (andesitic) and dacitic magmas are most common. Mount Rainier has less compositional diversity than many composite cones as it consists of mostly andesitic lava flows and lahar deposits.
Stratovolcanoes, also known as composite cones, are the most picturesque and the most deadly of the volcano types. Their lower slopes are gentle, but they rise steeply near the summit to produce an overall morphology that is concave in an upward direction.
A stratovolcano, or composite volcano, is a large and steep-sided volcanic cone built by explosive and effusive eruptions. These volcanoes are characterised by their symmetrical shape and layers of solidified lava flows, ash, and other volcanic debris.
