1 1 0. For most, an active volcano is one that has experienced some activity within the last 10,000 years. Lakes located in dormant or extinct volcanoes tend to have fresh water, and the water clarity in such lakes can be exceptional …
Lv 5. Crater lakes covering active (fumarolic) volcanic vents are sometimes known as volcanic lakes, and the water within them is often acidic, saturated with volcanic gases, and cloudy with a strong greenish color. Crater Lake in Oregon is a fine example.
Although Crater Lake has been dormant for about 5,000 to 6,000 years, there could be another eruption someday in the future and Mount Mazama might grow back. The low-rimmed Kurile Lake caldera was formed in two stages during the late Pleistocene and early Holocene. However, there is some disagreement between scientists about the definition of what an extinct, dormant and active volcano is.
Having a maximum depth of 594 m (1,949 ft), Crater Lake is the deepest lake in the United States. The descriptions of volcanic craters go on, and on.

Volcanoes are found in three states – extinct, dormant and active.
It is part of the area of the "east Eifel volcanic field". The long history of volcanism at Mount Mazama strongly suggests that this volcanic center will be active in the future. The man fell 800 feet down into the caldera near Rims Village, the US Coast Guard said. For example, the crater lake of Kawah Ijen in Indonesia has a pH of under 0.5. The little islands are formed by fumeroles, small gas release cones inside the main crater. The name refers to Mount Tabor, Israel . 2 hours ago Report. (CNN)A person was rescued Monday after falling into Oregon's Crater Lake -- a dormant volcano. Mount Tabor is an extinct or dormant volcanic vent, the city park on the volcano, and the neighborhood of Southeast Portland, Oregon that surrounds it. It was named by Plympton Kelly, son of Oregon City pioneer resident Clinton Kelly .
The active crater measuring 950x600 m is known for its rich sulphur deposits which are being quarried. Crater Lake in Oregon is a fine example. Yes, it is not unusual for a lake to form in an extinct or dormant volcano.
Kurile Lake caldera is one of the most impressive volcanic features in Kamchatka. Layers of lava flows from these volcanoes are visible in the caldera walls and in landmarks along the south rim of Crater Lake, including Applegate and Garfield Peaks. True, except that it is still active. Yes, it is not unusual for a lake to form in an extinct or dormant volcano. It contains four lake-filled maars called Blue Lake, Valley Lake, Leg of Mutton Lake, and Browns Lake. As it ejected matter the cone built up under the sea and eventually surfaced.
The first caldera-forming eruption took place about 41,500 radiocarbon years ago. The deep, active crater is between the peaks and fills with a crater lake between major eruptions. It lies within the eastern part of the massive Pauzhetka caldera, but is considered as a separate volcanic system here. Ijen volcano in East Java contains the world's largest acidic volcanic crater lake, called Kawah Ijen, famous for its turquoise color. The descriptions of volcanic craters go on, and on. Both Brown and Leg of Mutton lakes are dry in recent years, due to the lowering of the water table. Laacher See or Laach Lake (in English) is a crater lake or more exactly a caldera lake in the Rhineland-Palatinate, Germany, situated close to the cities of Koblenz, Mayen (11 km), and Andernach (14 km). The crater inside the extinct volcano named Diamond Head in Hawaii is home to a small military base. Also significant are many faults near Crater Lake that clearly have been active in the recent past. Crater lake may refer to: Impact crater lake; Volcanic crater lake; Crater Lake (disambiguation) This disambiguation page lists articles associated with the title Crater lake. Crater Lake partly fills one of the most visually spectacular calderas of the world, an 8-by-10-km (5-by-6-mi) basin more than 1 km (0.6 mi) deep formed by collapse of the volcano known as Mount Mazama during a series of explosive eruptions about 7,700 years ago. Although Crater Lake has been dormant for about 5,000 to 6,000 years, there could be another eruption someday in the future and Mount Mazama might grow back.
