چکیده

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 across this major eruptive event.

Re-evaluation of Scrapers Reduction Model Using Geometric Index of Reduction (Mar-Tarik Middle Paleolithic Assemblages)

Paleolithic lithic assemblages are traditionally described on the bases of presence of a variety of tool types(typology) and of different knapping technologies. In this study we tried to investigate whether the presence ofdifferent groups of scrapers in the Mar-Tarik site assigned to the Middle Paleolithic represent specific function orjust different stages of the reduction process and constant...

Youngest Toba Tuff in the Son Valley, India: a weak and discontinuous stratigraphic marker

Investigation of the climatic and environmental impacts of the Youngest Toba Tuff (YTT, ∼74 ka BP) eruption of Toba volcano, Sumatra, is crucial for understanding the consequences of the eruption for contemporaneous human populations. The Middle Son Valley, in India, was the first locality on the Indian subcontinent where the YTT was reported. The ash bed forms a discontinuous layer stretching ...

The super-eruption of Toba, did it cause a human bottleneck?

Lake Toba, Sumatra, Indonesia, is the site of the largest volcanic explosion in the late Pleistocene, which occurred about 73,500 ( 2000) years ago (Chesner et al., 1991, Bühring & Sarnthein 2000). It has been asserted by Ambrose (1998) and others (Rampino & Self 1992, Rampino & Ambrose 2000, Rampino 2002) that the eruption gave rise to a “volcanic winter” of such a catastrophic scale that it c...

Several intriguing questions are of major interest in studying the Middle Paleolithic period. A challenging enigma concerns the southeasternmost spread of the Neanderthal sub-groups “which inhabited a vast geographical area extending from Europe to western Asia and the Middle East” (Febre, Condemi, Degioanni, 2009: 1), a topic of major importance, the discussion of which has been avoided by mos...

The Toba Caldera Complex

The Toba Caldera in Indonesia is one of the most remarkable volcanic features formed during Quaternary geologic time. Its rich history of research for over a century has yielded important information on the physical volcanology of silicic calderas and super-eruptions, geochemical evolution of silicic magma bodies, and geophysical imaging of active sub-volcanic systems. During the past 1.3 my, t...
