not always... but it's likely happen when there are ring structure or cone sheet dikes occur as intrusive volcanic structures when the eruption happen and triggering it..
It is a cauldron-like volcanic feature usually formed by the collapse of land fallowing a volcanic eruption.
It is called a caldera. It is a cauldron-like volcanic feature usually formed by the collapse of land following a volcanic eruption, such as the one at Yellowstone National Park in the US. They are sometimes confused with volcanic craters.(wikipedia). Hope that helped :-D
Only the most violent volcanic eruptions feature a pyroclastic flow.
It is a caldera. A caldera is a cauldron-like volcanic feature usually formed by the collapse of land following a volcanic eruption.
A good candidate for that title is the Island Park Caldera. This caldera formed during the largest eruption of the Yellowstone Supervolcano about 2.1 million years ago. It is 40 by 50 miles across and was created by one of the largest volcanic eruptions of the last 10 million years, second only to the Lake Toba eruption 74,000 years ago.
Which volcanic feature did you find most difficult to identify? Explain why.
Volcanic rock and many crator
The most violent volcanic eruptions are found in destructive/convergent plate boundaries. 80% of the world's active volcanoes are found occur along destructive boundaries. Acid-lava and composite volcanoes also cause the most violent eruptions as the lava is viscous and the opening of the volcano is sometimes blocked by hardened lava, causing a huge massive explosion during the eruption.
Krakatoa is a Caldera Volcano.A caldera is a cauldron-like volcanic feature usually formed by the collapse of land following a volcanic eruption. They are sometimes confused with volcanic craters. The word comes from Spanish caldera, and this from Latin CALDARIA, meaning "cooking pot." In some texts the English term cauldron is also used.In 1815, the German geologist Leopold von Buch visited the Las Cañadas caldera of Teide on Tenerife, and the Caldera de Taburiente on La Palma, both in the Canary Islands. When he published his memoirs he introduced the term caldera into the geological vocabulary.
Parallel belts of folded mountains and volcanic mountains
