A) 280 km3 (67 mi3)
B) 670 km3 (161 mi3)
C) 2,800 km3 (670 mi3)
D) 6,700 km3 (1,606 mi3)

Answer 1

The Toba volcano in Indonesia ejected approximately 2,800 km3 (670 mi3) of material in its supereruption around 74,000 years ago. It had significant global consequences, including a volcanic winter that affected the climate and potentially impacted human populations at the time.
