Why is Mount Pinatubo a stratovolcano?

Pinatubo, a large volcano on the Philippine isle of Luzon, is a stratovolcano, or composite volcano. Stratovolcano is the name given to volcanoes whose repeated eruptions have left layers of volcanic materials built-up on top of each other, forming a mountain.

What type of volcano Mount Pinatubo belong and why?

Modern Mount Pinatubo is a dacite-andesite dome complex and stratovolcano that is surrounded by an extensive apron of pyroclastic-flow and lahar deposits from large explosive dacitic eruptions.

Is Mount Pinatubo an example of composite volcano?

Mount Pinatubo is one of a chain of composite volcanoes (fig. 1) that constitute the Luzon volcanic arc. The arc parallels the west coast of Luzon and reflects eastward-dipping subduction along the Manila trench to the west (Defant and others, 1989).

What type of volcano is Mount Pinatubo active dormant or extinct?

Mount Pinatubo is considered an active volcano, a classification which requires an eruption within the last 10,000 years.

What type of plate boundary is Mount Pinatubo on?

Where the Eurasian and Philippine plates meet, these two plates are responsible for forming the volcano. The plate movement of Mount Pinatubo is on a convergent plate boundary. Meaning, Pinatubo is at a subduction zone when the two plates of the Earth’s crust converge, one subducting or moving under the other.

What type of volcano is Mount Mayon?

stratovolcano

Mayon, located in the Philippines, is a highly active stratovolcano with recorded historical eruptions dating back to 1616. The most recent eruptive episode began in early January 2018 that consisted of phreatic explosions, steam-and-ash plumes, lava fountaining, and pyroclastic flows (BGVN 43:04).

What type of volcano is Mt Fuji?

stratovolcano

Mount Fuji is a composite cone, or stratovolcano. Composite cones, formed by violent eruptions, have layers of rock, ash, and lava. Mount Fuji is a symbol of Japan.

What type of volcano is Mojave volcano?

cinder cones

Surrounded by a sea of hardened lava flows, these little volcanos—cinder cones—began erupting into existence 7.6 million years ago. Lava last flowed just 10,000 years ago. Abundant and well preserved, these geo- logic features were designated as Cinder Cone National Natural Landmark in 1973.

What type of volcano is Mount Apo?

stratovolcano

Mount Apo is a flat-topped, 2,954 m (9,692 ft) high stratovolcano with three peaks. The southwest peak has the highest elevation and is topped by a 200 m (656 ft) wide crater that contains a small lake. The volcanic history of Mount Apo is poorly known but eruptions have produced andesitic-to-dacitic lava.

What type of volcano is Mount Kanlaon?

stratovolcano



Canlaon volcano (also spelled Kanlaon), the most active of the central Philippines, forms the highest point on the island of Negros. The massive 2435-m-high stratovolcano is dotted with fissure-controlled pyroclastic cones and craters, many of which are filled by lakes.

What are the volcano types?

The most well-known types of volcanoes are cinder cones, composite volcanoes (stratovolcanoes), and shield volcanoes. Several other types of volcanoes exist and are part of the diversity of volcanic landforms found on land.

What are 4 different types of volcanoes?

Geologists generally group volcanoes into four main kinds–cinder cones, composite volcanoes, shield volcanoes, and lava domes.

What are the 5 main types of volcanoes?

5 Types of Volcanoes



  • Composite or Strato-volcanoes: A composite volcano is also known as strato-volcano because composite strata or layered structure is formed due to the eruptive material. …

What are the 6 types of volcanoes?

There are six types of volcanoes. They make up all the volcanoes on Earth. The six types are Cinder Cone Volcano, Stratovolcano, Shield Volcano, Rhyolite caldera complexes, Monogenetic fields, and Flood Basalts.

What are the 3 main types of volcanoes and their characteristics?

There are three types of volcanoes: cinder cones (also called spatter cones), composite volcanoes (also called stratovolcanoes), and shield volcanoes. Figure 11.22 illustrates the size and shape differences amongst these volcanoes. Shield volcanoes, which get their name from their broad rounded shape, are the largest.

What is the base diameter of Pinatubo?

The Eruption

The caldera reduced the peak from 1745 meters (5725 feet) to 1485 meters (4872 feet) high is 2.5 kilometers (1.5 miles) in diameter.



How are volcanoes classified?

Volcanoes are classified as active, dormant, or extinct. Active volcanoes have a recent history of eruptions; they are likely to erupt again. Dormant volcanoes have not erupted for a very long time but may erupt at a future time. Extinct volcanoes are not expected to erupt in the future.

How do volcano lodges classify volcanoes?

Two basic classifications of volcanoes are based upon the type of eruption they produce: explosive (or central) and quiet (or fissure). Explosive eruptions are caused by the buildup of gasses under highly viscous (thick and slow-flowing) magma trapped deep within the volcano.

What is a Class C volcano?

Class C: Volcanoes which are categorized as particularly dangerous by the International Association of Volcanology And Chemistry of the Earth’s Interior (IAVCEI)

What are the two primary types of volcanoes?

Strictly speaking there are two broad types of volcano, a stratovolcano and a shield volcano, although there are lots of different volcanic features that can form from erupted magma (such as cinder cones or lava domes) as well processes that shape volcanoes.

What are the Three Sisters volcanoes?

Three Sisters are a cluster of volcanoes, composed of North Sister, Middle Sister, and South Sister. They are located approximately 25 km SW of Sisters, OR. North Sister is considered extinct, and Middle Sister has not erupted for 14,000 years.



What is the most common type of volcano?

Cinder cone volcanoes

Cinder cone volcanoes (also called scoria cones) are the most common type of volcano, according to San Diego State University, and are the symmetrical cone-shaped volcanoes we typically think of.
