What is the saucer shaped depretion on top of a volcano?
It is called a crater. The area around the sides is the crater rim. If the volcano has collapsed into an empty magma chamber, this is called a caldera, and can exist for both tall or wide volcanoes.
How big is Krakatoa's crater?
Krakatoa's crater, formed by the catastrophic eruption in 1883, is approximately 7 kilometers (about 4.3 miles) wide. The eruption led to the collapse of the island's volcanic structure, creating a caldera that is part of the larger Sunda Strait region. Since then, a new volcanic island, Anak Krakatau, has emerged within the caldera, further altering the landscape. The area remains an active volcanic site, continually reshaping the crater's characteristics.
Area of the largest volcanic crater?
The largest volcanic crater is Lake Tobi. This volcanic crater lake has an area of 1,130 km². It has a depth of up to 505 meters.
What is the hollow area at the top of a volcano?
The hollow area at the top of a volcano is known as the crater. It is a bowl-shaped depression where volcanic activity occurs, such as eruptions, gas emissions, and lava flows. Craters can vary in size and depth depending on the type of volcano.
What is the largest volcanic crater and what is the area?
The largest volcanic crater in the world is located in Tanzania , Africa. It is 2,236 meters above sea level. The diameter is 19 km and its surface measures no less than 304 kilometers squared.

What is the area of Toba caldera?
The area of Lake Toba is 440 square miles, or 1130 square kilometers. It is the largest volcanic lake on Earth, and is part of the Toba caldera complex in Indonesia.

What is the meaning of crater?
A crater can be a number of things, but there are a pair of definitions, one from geology and one from astronomy, that usually cover the bulk of the applications. A crater can refer to a volcanic crater (caldera), or it can refer to an impact crater resulting from a rock from space slamming into a planet, moon or other body.

What is the area of the largest volanic crater in Indonesia?
479.300.987.000 feet
Is a caldera another name for a magma chamber?
No. A magma chamber is the area under a volcano where molten rock is stored. A caldera is a depression in the ground formed during an exceptionally violent volcanic eruption. A caldera forms when a volcano drains a large volume of magma from the magma chamber, causing the volcano to collapse into the space left behind.
What is the bowl shaped area at the volcanoes opening?
The opening may have a crater, more technically called a "caldera."
Is the long valley caldera still active?
The Long Valley Caldera is still considered an active volcanic area, as it has experienced ongoing seismic activity and the release of volcanic gases. While there is no imminent threat of an eruption, monitoring of the caldera continues to track any potential changes that may indicate increased volcanic activity.
Where is the largest volcanic crater and how is the area?
it is taupo new zealand and it is 234 sqmiles
