As water fills the formed depression inside the rim, Crater Lakes In India are created. The water may come from melting ice, groundwater circulation, precipitation, or hydrothermal fluids frequently in volcanic craters. It’s level increases until the incoming and departing water rates are balanced. Evaporation, subsurface seepage, and, in some locations, surface leakage or overflow when the lake level reaches the lowest point on its rim can all be single or many sources of water loss.
In such a saddle location, the only natural volcanic dam that can contain the lake’s upper portion is next to it. Suppose the lake level can leak through the dam or surface outflow across the dam. In that case, the included material will erode, lowering the lake level until a new equilibrium of water flow, erosion, and rock resistance is established. A breakout or outburst flood results from the volcanic dam part eroding quickly or failing catastrophically. All natural dam types experience these floods due to environmental alterations over time.
This article will teach us about the Example Of Crater Lake In India. There is only one Volcanic Crater Lake In India, Lonar Lake, located in Maharastra.

Example Of Crater Lake In India: Lonar Lake
- The sole alien impact crater is Lonar Lake, situated within the gigantic Deccan Traps, a large basaltic rock in India.
- The lake’s origin was long assumed to be volcanic, but it has since been determined to be an impact crater.
- A meteor or an asteroid collided to create Lonar Lake.
- Lonar Lake, often called Lonar Crater, is a saline, soda lake that lies close to Lonar in the Buldhana district of Maharashtra, India. It is a designated National Geo-heritage Monument.
- Lonar Lake was created due to a meteorite collision during the Pleistocene Period.
- It is one of just four known basaltic rock hyper-velocity impact craters worldwide.
- It is believed that Lonar Crater is the result of a meteorite strike. The water in the lake is both alkaline and salty.
- A variety of salts and sodas are present in the lake’s water. When the water level is reduced by evaporation during dry weather, large soda volumes are collected.
- A freshwater well may be found on the lake’s southern shore, close to two minor streams, Purna and Penganga.
Lonar Lake: Geographic Characteristics
The basin is surrounded by several minor hills and has an almost circular, oval-shaped shape with an 8-kilometre top circumference (five miles). The basin’s walls climb sharply at an angle of around 75 degrees. The lake is 4.8 kilometres around at the base of the sides (three miles).
Lonar Lake: Origin
The sole known alien impact crater within India’s enormous basaltic deposit known as the Great Deccan Traps is where Lonar Lake is located. Once considered volcanic, the lake is now understood to be an impact crater. A comet or an asteroid collision led to the formation of Lonar Lake. The impact origin of this crater has been established by the presence of plagioclase that has either undergone the transformation into maskelynite or has planar deformation characteristics. Plagioclase is thought to only undergo shock metamorphism following a hypervelocity collision, producing planar deformation characteristics.
The impact origin of Lonar Lake is supported by the impact deformation of the basalt layers that make up the crater rim, the shocked breccia inside the crater, the shatter cones present, and the non-volcanic ejecta blanket encircling the crater.
Lonar Lake: Lake Ecosystem
Regarding the lake’s chemical features, particularly the pH, there are two separate zones. Because of their differing pHs, the two zones do not combine. The inner zone has an alkaline pH of 11, whereas the outer region has a neutral pH of seven. Each area has its unique flora and wildlife. 160 birds, 46 reptiles, and 12 mammal species can be found around the lake. The teals, parakeets, larks, and robins are prominent migratory birds. The monitor lizard plays a significant role in the lake environment with chinkara, peafowl, and other species. Gazelles.
Crater Lakes In India: FAQs
The name of the Volcanic Crater Lake In India is Lonar Lake.
Lonar Lake is located in the Buldhana district of Maharashtra, India.
A caldera or volcanic crater that contains water is known as a crater lake. The best example of an Indian crater lake is Lonar Lake.
The Deccan trap region, which includes Maharashtra and parts of Gujarat, Karnataka, and Madhya Pradesh, is found in the Deccan Plateau’s northwest.
Once believed that Lonar Lake was formed as the effect of craters of volcanic eruption, but now it is believed that Lonar Crater is the result of a meteorite strike.
