Calderas

When large volumes of magma are erupted over a short time, structural support for the crust above the magma chamber is lost. The ground surface then collapses downward into the partially emptied magma . These are the most powerful and catastrophic types of volcanoes in a category by themselves because of the unique way in which they form. This type of volcano is shaped more like an inverse volcano. A caldera is a volcanic feature formed by the collapse of a volcano into itself, making it a large, special form of volcanic crater.

A caldera collapse is usually triggered by the emptying of the magma chamber beneath the volcano, as the result of a large volcanic eruption.

If enough magma is erupte the emptied chamber will . The fractured rock above the magma chamber collapsed to produce a massive . A caldera is a depression created after a volcano partially collapses after releasing the majority of its magma chamber in an explosive eruption. Also called Bathtubs Volcanoes). It was Charles Darwin who said Nothing, not even the wind that blows, is so unstable as the crust of this earth. These volcanoes are the deadliest, stickiest, nasttiest, gassiest of the entire lot. Their eruptions can be earth shaking . When an erupting volcano empties a shallow-level magma chamber, the edifice of the volcano may collapse into the voided reservoir, thus forming a steep, bowl-shaped depression called a caldera (Spanish for kettle or cauldron).

These features are highly variable in size, ranging from 1-1km in diameter.

Of all the volcanic features on Earth, calderas can be the largest. Calderas form during massive volcanic eruptions where large portions of the surface collapse into the emptying magma chamber below. Pictured right: Upper image shows the initial phase of an . Caldera : Caldera , (Spanish: “cauldron”) large bowl-shaped volcanic depression more than one kilometre in diameter and rimmed by infacing scarps. Calderas usually, if not always, form by the collapse of the top of a volcanic cone or group of cones because of removal of the support formerly furnished by an.

The removal of large volumes of magma may result in loss of structural support for the overlying rock, thereby leading to collapse of the ground and formation of this type of large depression.

Calderas are different from craters, which are smaller, circular depressions created primarily by explosive excavation . Borrowed from Spanish caldera (“cauldron”), from Late Latin caldāria (“warm bath”), from Latin caldārium. A large crater formed by a volcanic .

Calderas are large volcanic depressions formed by collapse of the summit or flanks of a volcano into underlying chambers evacuated by very large explosive eruptions or the effusion of large volumes of lava flows.

Caldera in the Spanish language means kettle or cauldron in geological literature, it has come to be known as a volcanic collapse crater. The Valles caldera of New Mexico is a beautiful example of a resurgent caldera. The benefits of hot tub use add up over time.
