What is special about Lake Toba?
Lake Toba is an extraordinary natural wonder of the world. This enormous crater lake consists of an island almost the size of Singapore in its center. At over 1,145 square km, and a depth of 450 meters, Lake Toba is actually more like an ocean.
What caused Lake Toba?
The ancient lake has been formed by a steep-walled caldera produced during the Toba volcanos eruption, the largest known volcanic eruption on the planet in the past two million years. ... The eruption had created Lake Toba and triggered climate change.
When did Toba last erupt?
Photo by Tom Casadevall, 1987 (U.S. Geological Survey) The 35 x 100 km Toba caldera was formed during four powerful explosive eruptions beginning 1.2 million years ago. The latest of these, about 74,000 years ago, was one of the world's largest known Quaternary eruptions, producing the Young Toba Tuff (YTT).
Is Toba active dormant or extinct?
"Toba remains alive and active today." As large as the Toba eruption was, the reservoir of magma below the caldera is much, much greater, the researchers say.
What would happen if Mount Toba erupted?
But approximately 75,000 years ago in Indonesia, an eruption of similar scale occurred, and the supervolcano responsible remains active. Situated in the midst of a mountain range in northern Sumatra, the tranquillity and natural beauty of Lake Toba makes it a popular tourist location.
Will Toba volcano erupt again?
The researchers say that an extra four cubic kilometres of magma builds up in Toba every thousand years. This means that next equivalent super-eruption would occur in 600,000 years – though smaller ones could happen in the meantime.
Can caldera erupt?
Depending on their intensity and duration, volcanic eruptions can create calderas as much as 100 kilometers (62 miles) wide. A caldera-causing eruption is the most devastating type of volcanic eruption. It permanently alters the environment of the surrounding area.
When did Mount Toba erupt?
The explosion of the Toba supervolcano, located on the modern island of Sumatra, some 74,000 years ago was Earth's largest volcanic eruption in the past 28 million years.
Is there a supervolcano in Utah?
The Wah Wah Springs Caldera is a supervolcanic eruption remnant discovered in 2013 in Utah. It emitted 5500 to 5900 km3 of tephra, as the Wah Wah Springs Tuff, about 30.06 million years ago.
What volcano could destroy the world?
YELLOWSTONE "SUPERVOLCANO" (U.S.) Last erupted: 640,000 years agoEffects of a major eruption: When the Yellowstone Caldera, or "supervolcano," in Yellowstone National erupts again, it will render a huge swath of North America, from Vancouver to Oklahoma City, uninhabitable.
Did Toba cause the ice age?
Paleoclimate evidence suggests that the Toba eruption, which occurred during the last ice age, emitted lots of sulfur dioxide--vastly more than Mount St. Helens did. ... Some scientists have suggested that Toba caused the deep freeze and that perhaps such an event happening today could bring on a new ice age.
Did population drop 75000 years ago?
According to the Toba catastrophe theory, a massive volcanic eruption changed the course of human history by severely reducing the human population. This may have occurred when around 70–75,000 years ago the Toba caldera in Indonesia underwent a category 8 or "mega-colossal" eruption on the Volcanic Explosivity Index.
How often does Yellowstone caldera erupt?
How often do volcanic eruptions occur at Yellowstone? Three extremely large explosive eruptions have occurred at Yellowstone in the past 2.1 million years with a recurrence interval of about 600,000 to 800,000 years.
