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… Expand
Continuity and change in the lithic industries of the Jurreru Valley, India, before and after the Toba eruption
Lithic assemblage variability is synthesized and discussed for seven open sites and one rockshelter from the Jurreru Valley in the Kurnool district of southern India. The sites span the last c.77,000Expand
Cryptotephra from the 74 ka BP Toba super-eruption in the Billa Surgam caves, southern India
Abstract The ∼74 ka BP Youngest Toba Tuff (YTT), from the largest known Quaternary volcanic eruption, has been found for the first time as a non-visible ( crypto -) tephra layer within the BillaExpand
The Toba volcanic super-eruption, environmental change, and hominin occupation history in India over the last 140,000 years
A prolonged, interdisciplinary fieldwork program was initiated in India to investigate the impact of the Toba super-eruption on terrestrial ecosystems and hominins. Fieldwork was centered on theExpand
Building a tephrostratigraphic framework for the Paleolithic of Central Anatolia, Turkey
The Central Anatolian Volcanic Province (CAVP) in Turkey preserves widespread deposits of Quaternary tephra, presently associated with a small but growing number of Paleolithic archaeological sites.Expand
A Toba-scale eruption in the Early Miocene : the Semilir eruption, East Java, Indonesia
The Indonesian archipelago is well-known for volcanic activity and has been the location of three catastrophic eruptions in the last million years: Krakatau, Tambora and Toba. However, there are noExpand
The 74 ka Toba super-eruption and southern Indian hominins: archaeology, lithic technology and environments at Jwalapuram Locality 3
Hominins living in southern India 74,000 years ago faced a deteriorating environment, as the global climate moved from interglacial into full glacial conditions. At the same time, South AsianExpand
Did the 73 ka Toba super-eruption have an enduring effect? Insights from genetics, prehistoric archaeology, pollen analysis, stable isotope geochemistry, geomorphology, ice cores, and climate models
Abstract The potential impact of the ∼73 ka Toba super-eruption upon global and regional climate, terrestrial ecosystems and prehistoric human populations remains unclear. Evidence from genetics,Expand
Understanding the overestimated impact of the Toba volcanic super-eruption on global environments and ancient hominins
Abstract The ~74 ka Toba super-eruption was the largest known explosive volcanic event of the past 2.5 million years and has been held responsible for presumed dramatic global cooling and large-scaleExpand
A southern Indian Middle Palaeolithic occupation surface sealed by the 74 ka Toba eruption: Further evidence from Jwalapuram Locality 22
This paper reports further evidence from an archaeological occupation surface in southern India that was buried by tephra from the Toba volcanic super-eruption ca. 74,000 years ago. The open-airExpand
Grain size distribution analysis of sediments containing Younger Toba tephra from Ghoghara, Middle Son valley, India
Abstract The Toba super-eruption in northern Sumatra ∼74 ka was the largest eruption of the Quaternary period. Terrestrial deposits of distal Toba tephra have been found across the IndianExpand


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 ofExpand
Toba Ash on the Indian Subcontinent and Its Implications for Correlation of Late Pleistocene Alluvium
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 basins, itExpand
All toba tephra occurrences across peninsular India belong to the 75,000 yr B.P. eruption
Abstract 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, theExpand
New Geochemical Evidence for the Youngest Toba Tuff in India
Abstract New geochemical data on tephra samples from a layer present at several archeological sites in India support correlation of this layer to the Youngest Toba Tuff, erupted from northern SumatraExpand
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. InExpand
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 theExpand
Limited global change due to the largest known Quaternary eruption, Toba ≈74 kyr BP?
Abstract The ≈74 kyr BP “super-eruption” of Toba volcano in Sumatra is the largest known Quaternary eruption. On the basis of preserved deposits, the eruption magnitude has been estimated at ≈7×10 15Expand
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 toExpand
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),Expand
The super-eruption of Toba, did it cause a human bottleneck?
The probable effect of the Toba eruption and the evidence that it caused the putative bottleneck are discussed. Expand
