The Youngest Toba Tuff (YTT) eruption, which occurred in Indonesia 74,000 years ago, is one of Earth's largest known volcanic events. The effect of the YTT eruption on existing populations of humans, and accordingly on the course of human evolution, is debated. Here we associate the YTT with archaeological assemblages at Jwalapuram, in the Jurreru River valley of southern India. Broad continuity of Middle Paleolithic technology across the YTT event suggests that hominins persisted regionally…

Dispersal of ash in the great Toba eruption, 75 ka
One of Earth9s largest known eruptions, the Toba eruption of 75 ka, erupted a minimum of 2800 km 3 of magma, of which at least 800 km 3 was deposited as ash fall. This ash may be entirely of
Toba Ash on the Indian Subcontinent and Its Implications for Correlation of Late Pleistocene Alluvium
Abstract The Toba ash occurs extensively in the Indian subcontinent and marks a ca. 74,000-yr-old event. In the Bay of Bengal and Indian Ocean it is about 10 cm thick, whereas in several alluvial
All Toba Tephra Occurrences across Peninsular India Belong to the 75,000 yr B.P. Eruption
A controversy currently exists regarding the number of Toba eruptive events represented in the tephra occurrences across peninsular India. Some claim the presence of a single bed, the 75,000-yr-old
Eruptive history of Earth's largest Quaternary caldera (Toba, Indonesia) clarified
Single-grain laser-fusion {sup 40}Ar/{sup 39}Ar analyses of individual sanidine phenocrysts from the two youngest Toba (Indonesia) tuffs yield mean ages of 73{plus minus}4 and 501{plus minus}5 ka. In
The Middle Palaeolithic of Arabia: Implications for modern human origins, behaviour and dispersals
The Middle Palaeolithic record of the Arabian Peninsula can provide crucial evidence for understanding human dispersal. The authors summarise the archaeological evidence and suggest some of the
Volcanic winter and accelerated glaciation following the Toba super-eruption
THE eruption of Toba in Sumatra 73,500 years ago was the largest known explosive volcanic event in the late Quaternary1. It could have lofted about 1015 g each of fine ash and sulphur gases to
Climate-Volcanism Feedback and the Toba Eruption of ∼74,000 Years Ago
Abstract A general feedback between volcanism and climate at times of transition in the Quaternary climate record is suggested, exemplified by events accompanying the Toba eruption (∼74,000 yr ago),

TLDR
If Toba caused the bottlenecks, then modern human races may have differentiated abruptly, only 70 thousand years ago, and high genetic diversity in modern Africans may reflect a less severe bottleneck rather than earlier population growth.
