Stratovolcano The last eruption of this stratovolcano occurred in March 1944. A stratovolcano, also known as a composite volcano, is a conical volcano built up by many layers (strata) of hardened lava, tephra, pumice, and volcanic ash. Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile and periodic explosive eruptions and effusive eruptions, although some have collapsed craters called calderas.

Stratovolcano Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile and periodic explosive eruptions and effusive eruptions, although some have collapsed craters called calderas. The lava flowing from stratovolcanoes typically cools and hardens before spreading far due to high viscosity.The magma forming this lava is often felsic, having high-to-intermediate levels of silica (as in rhyolite, dacite, or andesite), with lesser amounts of less-viscous mafic magma.ubduction-zone stratovolcanoes, such as Mount St. Helens, Mount Etna, and Mount Pinatubo, typically erupt with explosive force: the magma is too stiff to allow easy escape of volcanic gases. As a consequence, the tremendous internal pressures of the trapped volcanic gases remain in the pasty magma.

Pinatubo, Philippines Pinatubo is a stratovolcano on the island of Luzon. Its eruptive history is divided into two distinct parts. The first part of this history involves an ancestral volcano to Pinatubo. This period includes all eruptions to about 35 thousand years ago. Ancestral Pinatubo was a stratovolcano made of andesite and dacite.

FAQ What is the origin of the cocoa tree? Cocoa beans, from which cocoa products are derived, come from the cocoa tree, which is the species Theobroma cacao. The genus Theobroma, from which the cocoa tree species comes, originated millions of years ago in South America, to the east of the Andes. However, despite our knowing the origin of the genus Theobroma, the birthplace of Theobroma cacao is not so certain and there is no consensus on where cocoa originated.

volcano The lava flows associated with shield volcanos, such as Mauna Loa, on Hawaii, are very fluid. ◇ A volcano composed of steep, alternating layers of lava and pyroclastic materials, including ash, is called a stratovolcano. Stratovolcanos are associated with relatively viscous lava and with explosive eruptions.

Volcano Live stratovolcano. The Mt Pinatubo eruption of 1991 was the second largest eruption of the 20th century. Mount Pinatubo Volcano had been dormant for 400 years. Before 1991 Pinatubo was an inconspicuous volcano which was known to be active in the past 1000 years and was the site of a failed geothermal development.he largest eruption at Mt Pinatubo volcano occurred 35,000 years ago, and produced pyroclastic flow deposits up to 100 m thick on all sides of the volcano. The Sacobia eruption period 17,000 years ago produced two debris flow deposits which are visible on the north bank of the Sacobia River.

Composite Volcano Composite Volcano. A composite volcano forms in subduction zones when a crustal plate is forced into the mantle and begins to melt. Andesite, dacite and rhyolite lavas are the primary types of lava that form these volcanoes.Eruptions on the volcanoes often alternate between tephra and lava flows. Subduction zone volcanoes.Geologists often use the term stratovolcanoes to describe the mountains that form in subduction zones.The volcanoes form on the continental side of a subduction zone.ruptions on the volcanoes often alternate between tephra and lava flows.

- Mount Pinatubo (Filipino: Bundok Pinatubo) is an active stratovolcano in the Cabusilan Mountains on the island of Luzon, near the tripoint of the Philippine provinces of Zambales, Tarlac, and Pampanga. Before the volcanic activities of 1991, its eruptive history was unknown to most people.t injected more particulate into the stratosphere than any eruption since Krakatoa in 1883. Over the following months, the aerosols formed a global layer of sulfuric acid haze. Global temperatures dropped by about 0.5 °C (0.9 °F) in the years 1991-93, and ozone depletion temporarily increased substantially.

Volcano Stratovolcanoes or composite volcanoes are tall conical mountains composed of lava flows and other ejecta in alternate layers, the strata that gives rise to the name. Stratovolcanoes are also known as composite volcanoes because they are created from multiple structures during different kinds of eruptions.

Vesuvius, Italy Compare to the map below. The Somma Rim, a caldera-like structure formed by the collapse of a stratovolcano about 17,000 years ago, is visible as an arcuate dark area to the right and above Vesuvius.The Bay of Naples is on the lower left.he oldest dated rock from the volcano is about 300,000 years old. It was collected from a well drilled near the volcano and was probably part of the Somma volcano. After Somma collapsed about 17,000 years ago, Vesuvius began to form. Vesuvius is a stratovolcano.
