What type of volcano is Barren Island?

stratovolcano
A part of India, Barren Island is one of the Andaman Islands, and lies over the fault whose movement caused the tsunami on December 26, 2004. It is a stratovolcano composed of lava, rock fragments, and volcanic ash.

What is the classification of a volcano?

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.

What is the classification of disaster of volcanic eruption?

Hot magma, hot vapour, and gasses escape through a vent when they erupt. Volcanoes have played a major role in the formation of the Earth’s atmosphere, ocean, and continents throughout history. They are one of the natural disasters classified as a geophysical event (Low & Wirtz, 2010).

Is Barren Island an active volcano?

Barren Island, a possession of India in the Andaman Sea about 135 km NE of Port Blair in the Andaman Islands, is the only historically active volcano along the N-S-trending volcanic arc extending between Sumatra and Burma (Myanmar).

What is the three classification of volcanoes?

Each volcano is somewhat unique, but most volcanoes can be classified into one of several types. The most well-known types of volcanoes are cinder cones, composite volcanoes (stratovolcanoes), and shield volcanoes.

What are the classification of volcano in terms of cone?

The three cone shapes are cinder cones, shield cones, and composite cones or stratovolcanoes. The six eruption types are in order from least explosive to the most explosive; Icelandic, Hawaiian, Strombolian, Vulcanian, Pelean, and Plinian.

What is special about Barren Island?

Around 135 km northeast of Port Blair, the capital of the Andaman and Nicobar Islands, lies Barren Island, which is home to South Asia and India’s only active volcano!

Which island has an active volcano?

The Island of Maui has one active volcano, Haleakalā, which has erupted at least 10 times during the past 1,000 years. Kīlauea, the youngest and most active volcano on the Island of Hawai’i, erupted almost continuously from 1983 to 2018 at Pu’u’ō’ō and other vents along the volcano’s East Rift Zone.

What caused Barren Island to erupt?

The magnitude 9.3 Sumatra earthquake on 26 December 2004 was followed by eruptions of Barren Island on 28th May 2005. An ash plume was erupted from a vent on the W side of the summit. Lava flows were produced. The eruption may have been precipitated by the great Sumatra earthquake in December 2004.

How are volcanoes measured and classified?

VEI Table. The Volcanic Explosivity Index (VEI) is a scale that describes the size of explosive volcanic eruptions based on magnitude and intensity. The numerical scale (from 0 to 8) is a logarithmic scale, and is generally analogous to the Richter and other magnitude scales for the size of earthquakes.

How are you going to classify active volcanoes?

Put simply, the most popular way for classifying volcanoes comes down to the frequency of their eruption. Those that erupt regularly are called active, while those that have erupted in historical times but are now quiet are called dormant (or inactive). But in the end, knowing the difference all comes down to timing!

Which features would you look for to classify a volcano?

There is no easy answer to this question, as scientists classify volcanoes in several different ways, including size, shape, explosivity, lava type, and tectonic occurrence. Furthermore, these different classifications often correlate.

Why is volcanic activity classification necessary?

The warning time preceding volcanic events typically allows sufficient time for affected communities to implement response plans and mitigation measures.

How can you classify a volcano that have no recorded eruption but have evidence that erupted?

A dormant volcano is one that is active but not currently erupting, while an extinct volcano has not erupted in historic time and is unlikely to erupt in the future.

What is the classification of a volcano that has not erupted in the past 10000 years but has the potential to erupt in the future?

Volcanoes typically are categorized thusly: active (a volcano that has erupted in the past 10,000 years), erupting (an active volcano that is experiencing an eruption), dormant (an active volcano that has the potential to erupt again), and extinct (a volcano that has not erupted in over 10,000 years and is unlikely to …

What are the three volcanic features?

There are three places that volcanism commonly occurs. These are at hot spots, spreading centers and fault zones, and subduction zones.

Which type of volcano is most common?

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