Largest Lake In Indonesia

Largest Lake In Indonesia – Lake Toba (Indonesian: Danau Toba, Batak Toba: ᯖᯀᯬ ᯖᯬᯅ; romanized: Tao Toba) is a large natural lake in northern Sumatra, Indonesia, occupying the caldera of a super volcano. This lake is located in the middle of the northern part of the island of Sumatra, with an altitude of about 900 meters (2,953 ft), it stretches from 2°53′N 98°31′E / 2.88°N. 98.52°E / 2.88; 98.52 at 2°21′N 99°06′E / 2.35°N 99.1°E / 2.35; 99.1. The lake is about 100 kilometers (62 mi) long, 30 kilometers (19 mi) wide and up to 505 meters (1,657 ft) deep. It is the largest lake in Indonesia and the largest volcanic lake in the world.

Lake Toba is the site of a supervolcanic eruption estimated at VEI 8 that occurred 69,000 to 77,000 years ago.

Reflect climate change events. Recent advances in dating methods suggest a more precise identification of 74,000 years ago as the date.

This is the largest known explosive eruption on Earth in the last 25 million years. According to Toba’s catastrophe theory, it had global consequences for the human population; It killed most humans alive at the time and is believed to have created population shortages in central East Africa and India, affecting the geographic composition of the global human population to this day.

More concrete research has cast doubt on this theory and found no evidence of major changes in world population.

It has been accepted that the eruption of the Toba Caldera caused a volcanic winter with global temperature drops between 3 and 5 °C (5.4 and 9.0 °F), up to 15 °C (27 °F) at high latitudes. . Additional research at Lake Malawi in East Africa showed large amounts of ash deposited by the Toba Caldera eruption, even over long distances, but little indication of a significant climate influence in East Africa.

The Toba caldera in northern Sumatra includes four overlapping volcanic craters located on the “volcanic front” of Sumatra. At 100 by 30 kilometers (62 by 19 miles), it is the largest Quaternary caldera in the world and the fourth and youngest caldera. It crosses the three oldest caldera. Estimated 2,800 km

(670 cu mi) of pyroclastic material equivalent to dse rock, known as the Younger Toba Tuff, was released during one of the largest explosive volcanic eruptions in the geological history of the plate.

After this eruption, a resurfaced dome was formed in the new caldera, joining two half domes separated by a longitudinal grip.

At least four cones, four stratovolcanoes and three craters can be seen in the lake. The Tandukbua cone on the northwest side of the caldera has sparse vegetation, indicating an early age of several hundreds of years. In addition, Pusubukit volcano (Hill Cter) (1,971 m (6,467 ft) above sea level) on the southern side of the caldera is solfatarly active.

This is the last in a series of at least four caldera-forming eruptions at this location, with the previously known caldera forming around 1.2 million years ago. Largest Lake In Indonesia

Bill Rose and Craig Chesner of Michigan Technological University estimate that the total amount of material released in the eruption was at least 2,800 km.

(190 cu mi) that fell as dust mainly to the west. However, when more outcrops are available, Toba may have erupted at 3,200 km.

The eruption was large enough to deposit an ash layer about 15 cm (6 inches) thick across South Asia; At one site in central India, the current Toba ash layer is up to 6 m (20 ft) thick.

The collapse then formed a caldera that filled with water, creating Lake Toba. The island in the middle of the lake consists of a resurfaced dome.

The exact year of the eruption is unknown, but the ash deposit pattern indicates that it occurred during the northern summer because only the summer monsoon can deposit Toba ash into the South China Sea.

The eruption lasted for about two weeks, and the intense volcanic season caused the average global temperature to drop by 3.0 to 3.5 °C (5 to 6 °F) over several years. Greenland ice cores record pulses of real organic carbon reduction rates. Very few plants or animals in Southeast Asia will survive, and the eruption is likely to cause the extinction of the entire planet. However, Rampino and Self have discussed global cooling. Their conclusion is that the cooling has started before the eruption of Toba. This conclusion is supported by Lane and Zielinski, who studied the African Lake core with GISP2. They concluded that there was no volcanic season after the Toba eruption and that the high H2SO4 deposits did not cause long-term effects. Largest Lake In Indonesia

Furthermore, due to the low solubility of sulfur in magma, volatile emissions and climate impacts are likely to be limited.

Evidence from mitochondrial DNA studies suggests that humans may have experienced a genetic lock around this time that reduced genetic diversity below what would be expected from the age of the species. According to the Toba disaster theory, proposed by Stanley H. Ambrose from the University of Illinois at Urbana-Champaign in 1998, the effects of the Toba eruption may have reduced the size of the human population to only a few thousand individuals.

However, this hypothesis is not widely accepted because similar effects have not been observed in other animal species and paleoanthropology shows that there is no population block.

Ethnic blockade is now recognized as a founder effect outside of Africa, rather than an actual population reduction.

Since the big eruption about 70,000 years ago, small eruptions have also occurred in Toba. The small cone of Pusukbukit is formed on the southwest margin of the caldera and lava domes. The most recent eruption may be in Tandukbua, on the northwest side of the caldera, suggested by the lack of vegetation which may be due to an eruption in the last few hundred years.

Some parts of the caldera have shown uplift due to partial filling of the magma chamber, for example pushing Samosir Island and Uluan Pinsula above the surface of the lake. Sediments from a lake on Samosir Island indicate that it had a height of at least 450 m (1,476 ft).

Since the cataclysmic eruption. These uplifts are common in very large calderas, partly due to the increase in magma pressure underground. Toba is probably the largest resurgence caldera on Earth. Large earthquakes have occurred around the mountain, especially in 1987 along the southern shore of the lake at a depth of 11 km (6.8 mi).

In 2016, a study revealed that the Toba supervolcano has a magma chamber containing 50,000 cubic kilometers (12,000 cubic miles) of erupted magma, about 30 to 50 kilometers (19 to 31 miles) underground.

This makes the supervolcano’s magma chamber more than four times larger than the volume of Lake Superior in North America, and also larger than the magma chamber under Yellowstone.

Lake Toba is located near the Great Sumatra Fault, which runs along central Sumatra in the Sumatra Fault Zone.

The volcanoes in Sumatra and Java are part of the Sunda Arc, the result of the movement of the Indo-Australian Plate to the northeast, which is sliding under the Eurasian Plate that is moving to the east. The subduction zone in this area is very active: the seabed near the west coast of Sumatra has experienced several major earthquakes since 1995, including the 9.1 Indian Ocean earthquake in 2004 and the 8.7 earthquake in Nias-Simeulue in 2005, whose epitherm is approx. 300 km. (190 miles) from Toba.

Most of the people living around Lake Toba are ethnically Batak. Traditional Batak houses are characterized by their distinctive roofs (which curve upwards on each d, like the hull of a ship) and colorful decorations.

Parapat is located on the side of the lake, which is a transit point for tours to the lake and Samosir Island. Medan is about 173 km away from the city and is connected through the Trans-Sumatra Highway to Pematang Siantar by a 48 km road. Sisingamangaraja XII International Airport is located approximately 76 km from Parapat.

The flora of the lake includes various types of phytoplankton, emergent macrophytes, floating macrophytes and submerged macrophytes, while the surrounding countryside is a rain forest including tropical Sumatran pine forest areas in the upper slopes.

Fauna includes several species of zooplankton and botanical animals. Because the lake is oligotrophic (e.g. nutrients), the original fish fauna is relatively rare, and the only demics is Rasbora tongana (strictly speaking, almost demic, as also found in some tributary rivers that flow into the lake).

The latter species is threatened by deforestation (which causes siltation), pollution, changes in water levels and many fish species introduced into the lake.

On June 18, 2018, Lake Toba was the site of a ferry disaster in which more than 160 people died.
