Why is Lake Toba famous?
Lake Toba is the site of a supervolcanic eruption estimated at VEI 8 that occurred 69,000 to 77,000 years ago, representing a climate-changing event.
Is Lake Toba dormant?
“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.
Is Lake Toba bigger than Singapore?
3. Lake Toba is the largest volcanic lake in the world (and is bigger than Singapore)! It’s true! At over 1,140km2 and 505-metres deep, Lake Toba is almost like an ocean.
Will Lake Toba 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.

Is Mt Everest growing?
The collision between the two continental plates is still happening today. India continues to creep north by 5cm (2in) a year, causing Everest to grow by about 4mm (0.16in) per year (although other parts of the Himalayas are rising at around 10mm per year.
