Crater Lake – a lake formed by the water filling a volcanic crater (indentation on the top of the volcano), the caldera (depression, formed due to the failure of the summit of the volcano), Maar (the crater of the explosion) or an impact craterthat appeared in the fall of cosmic bodies on the surface of the Earth .
Crater Lake is usually a circle high wall and is usually filled with rain water. The lens most interesting crater lake.
Crater Lake in Chukotka. The diameter of the lake – about 12 kilometers and a maximum depth – 174 meters. Crater Lake was formed about 3.6 million years ago. For the main hypothesis, it is either a shock or volcanic crater:
This is a valid stratovolcano in the south of the Alaska Peninsula. The volcano is 10 km in diameter and has a caldera, filled a large lake, measuring 4.5 × 3 km, which was formed during the eruption of the volcano in 1912. The maximum height of atm, which is a crater lake – 2047 meters above sea level:
Caldera, a radius of 2 km was formed by a volcanic eruption about 800 years ago. Crater Lake has a depth of 250 meters and painted in a greenish color due to dissolved minerals. At the bottom of the lake there are cracks through which jets of gas rise.
Crater lake in the Rift Valley, Africa
Rift – a large linear depression in the earth’s crust. Rift valley is located between the highest mountain systems in Africa – Virunga, Rwenzori and Mitumba. In the Rift Valley is Lake, including Lake Tanganyika, which is the world’s longest freshwater lake and one of the deepest (1470 meters).
Crater Lake, Oregon
Crater Lake is known for its deep blue and clean water. It partially fills the caldera of the depth of 1220 meters, which appeared about 7700 years ago, after the destruction of Mount Mazama volcano.
The dimensions of the crater lake: 8 to 9.5 km. The average depth of 350 meters and the maximum – 595 meters. Photo from space:
This is the deepest lake in the U.S., the second deepest in North America.
Pinatubo volcano is located on the Philippine island of Luzon at 93 kilometers north-west of the capital Manila.
In the vast crater of 2.5 km in diameter, formed by the eruption of 1991, formed a crater lake with rain food.
“Lake of the five colors,” Japan
Mount Zao is located on the border of Yamagata and Miyagi prefectures. In the 1720s in the crater of the volcano after the eruption of the lake was formed OCAM. It is also called “five colors lake” because it changes color depending on the weather.
The diameter of the crater lake is 360 meters, and depth – 60 m
Crater Lake Taal volcano in the Philippines
Taal volcano is located in the Philippines, 50 kilometers from Manila.
Crater Lake fills the caldera with a diameter of 25-30 kilometers, which was formed after the eruption of the fittest 100-500 thousand years ago.
Crater Volcano Deribo sleeping, located at an altitude of 3042 meters, formed by the eruption of 3500 years ago. Its size – 5-8 km in diameter.

Crater lake at Mount Ruapehu, New Zealand
The current stratovolcano Ruapehu in New Zealand is the highest point of North Island (2797 meters).
At the top of the volcano (ma. photo above) is a crater lake:
Yak Loum, Cambodia
This beautiful lake is located at 4000-year-old volcanic crater. It is almost perfectly round – 720 meters in diameter and has a depth of 50 meters. Around the crater lake is a lush tropical forest with many exotic birds.
Kuril Lake, Russia
In the southern part of Kamchatka Peninsula is a large caldera, which has settled in the crater lake. Kurile Lake area – about 77 square meters. miles., the average depth of 195 meters, maximum depth of 316 meters. (Photo by Roman Murushkina ):
Kuril Lake. View from space:
Volcano Kelimutu height 1639 meters is on the Indonesian island of Flores. There are three crater lakes, each a different color.
In lakes, the various minerals dissolved Kelimutu, and because of this for a few years they change their color from black to turquoise, red-brown or green.
Keriz crater lake, Iceland
Located in the south of Iceland . Caldera, which is a crater lake, is composed of red or black volcanic rock. The depth of the caldera – 55 meters, width – 170 feet, age – 3000 years. The very shallow crater lake – only 7-14 meters in depth.
Crater Lake at Likankabure, Chile
Likankabur – high stratovolcano 5920 m above sea level. The crater is a lake covered with ice most of the year. This is one of the high mountain lakes in the world.
Geothermal Viti crater lake, Iceland
Askya – the current high stratovolcano 1510 m above sea level.
During a volcanic eruption in 1875, the caldera of about 45 square kilometers Two large lakes were formed. One of them – Viti crater lake geothermal diameter of about 100 m and a depth of about 7 meters. The water is milky blue. The photo is possible to distinguish swimmers of people:
Heaven Lake, North Korea, China
Crater Lake and Tianchi Cheongju is located on the border of North Korea and China. Yet it is called the Heavenly Lake.
The crater was formed as a result of a strong eruption in 970. Crater lake shore is very steep. Flowing from the river forms a lake in the crater wall of a deep gorge with steep ledges, where the waterfalls are formed. The largest of these is located at the outer edge of the crater and has a height of 50 meters.
Heaven Lake is listed in the Guinness Book of Records as the highest crater lake in the world – the height of the water surface is 2189 m
