Crater Lake is a volcanic crater lake in southern Oregon, USA. It is the main feature of Crater Lake National Park and is famous for its deep blue color and water clarity. The lake is fed solely by rainwater and snowmelt, with no inflowing or outflowing streams.
The type of volcano that crater lake is classified as is a cinder cone volcano.
What type of volcano is Crater Lake?
A stratovolcano is a type of volcano that is built up of layers of lava flows and pyroclastic deposits. These types of volcanoes tend to have a steep-sided conical form and are known for their explosive eruptions. The stratovolcano that is most well-known is Mount St. Helens, which is located in the state of Washington in the United States.
Cinder cones are the most common type of volcano in the National Park System. At least 24 units in the National Park System contain cinder cones. Wizard Island in Crater Lake is a cinder cone.
Is Crater Lake an active volcano
Crater Lake is considered a dormant volcano, but it is still part of the United States Geological Survey Cascades Volcano Observatory seismic monitoring network. The average depth of Crater Lake is 350 meters (1,148 feet), making it the deepest lake in the United States.
Crater Lake is actually not a crater at all. It is a caldera, formed from the collapse of a volcano’s magma chamber. The volcano that created the caldera, Mount Mazama, erupted about 7,000 years ago. The caldera filled with rain and snow, forming a lake.
Why is Crater Lake a stratovolcano?
Crater Lake is one of the world’s best known calderas and was formed about 6,850 years ago when Mount Mazama, a stratovolcano, collapsed. The caldera is about 6 miles (10 km) wide and was formed by a catastrophic pyroclastic eruption that released about 12 cubic miles (50 cubic km) of magma to the surface.
The Cascades ArcMount Mazama is one of the major volcanoes of the Cascades Arc. Crater Lake is located within the collapsed caldera of Mount Mazama on the crest of the Cascade Range in southern Oregon about 90 km (55 mi) north of the city of Klamath Falls and about 100 km (60 mi) northeast of Medford.
Is Crater Lake a shield cone?
The cone is about 1,000 years old and was formed by a series of explosive eruptions. It is the largest cinder cone in Crater Lake National Park and is surrounded by a field of smaller cinder cones.
Cinder cones are small, steep-sided volcanoes that are made up of bits of lava and ash. They can form by themselves or when new vents open on larger, existing volcanoes. Mauna Kea, a volcano on the American island of Hawaii, and Mount Etna, a volcano on the Italian island of Sicily, are both covered with hundreds of cinder cones.
What is a cinder cone volcano called
Parícutin Volcano is a cinder cone volcano located in the Mexican state of Michoacán. The volcano is approximately 1,200 feet tall and has been active since 1943. The most recent eruption occurred in 1952 and the volcano is currently inactive.
Mount Mazama is a mountain in the Cascade Range in Oregon, USA. It is the site of Crater Lake, which was formed when the mountain collapsed following a large eruption about 7,700 years ago.
Which volcano is a caldera?
A caldera is a large basin-shaped depression that forms when a volcano collapses in on itself. The Kilauea caldera on Kilauea, one of the volcanoes that make up Hawai’i, is one example. Another type of caldera is a resurgent caldera. These broad, vast calderas result when very large magma chambers empty quite forcefully, causing a series of pyroclastic flows.
Caldera magma chambers are located beneath volcanoes and are where magma is stored. When a very large, explosive eruption occurs that empties the magma chamber, the roof of the magma chamber can collapse to form a depression or bowl with very steep walls on the surface. These are calderas and can be tens of miles across.
What volcanic events formed Crater Lake
The climactic eruption of Mount Mazama formed Crater Lake in Oregon, USA. The eruption occurred about 7,700 years ago and created a caldera that is now filled with water. The lake is about 6 miles (10 km) wide and 1,943 feet (592 m) deep, making it the deepest lake in the US and the seventh deepest in the world. The lake is known for its clear blue water and is a popular tourist destination.
A volcanic arc is generally considered to be a chain of volcanoes that forms above a subduction zone. An island volcanic arc typically forms in an ocean basin as a result of ocean-ocean subduction. The Aleutian Islands off the coast of Alaska and the Lesser Antilles south of Puerto Rico are two examples of island volcanic arcs.
Is Crater Lake a meteor crater?
Crater Lake was not formed by a meteor. Mount Mazama, a 12,000 foot volcano, erupted and collapsed over 7,000 years ago, creating the formation we now know as Crater Lake. The explosion left a deep, large caldera in its place, only filling with rain and snow melt – no meteor required.
Shield volcanoes are some of the simplest volcanic features. They are dominated by fluid basaltic and andesitic lava flows that erupted over long periods of time. Shield volcanoes are very wide, but not very tall.
Warp Up
Crater Lake is a caldera, a type of volcano formed when a large, explosive eruption collapses inward, creating a large depression in the earth.
Based on the information provided, it is safe to conclude that Crater Lake is a shield volcano.
