Climate-Volcanism Feedback and the Toba Eruption of ∼74,000 Years Ago

  title={Climate-Volcanism Feedback and the Toba Eruption of ∼74,000 Years Ago},
  author={Michael R. Rampino and Stephen Self},
  journal={Quaternary Research},
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), the largest known late Quaternary explosive volcanic eruption. The Toba paroxysm occurred during the δ18O stage 5a-4 transition, a period of rapid ice growth and falling global sea level, which may have been a factor in creating stresses that triggered the volcanic event. Toba is estimated to have… Expand
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
Use of paleo-records in determining variability within the volcanism climate system
Abstract Volcanic eruptions that inject large quantities of sulfur-rich gases into the stratosphere have the capability of cooling global climate by 0.2–0.3°C for several years after the eruption.Expand
A 110,000-yr record of explosive volcanism from the GISP2 (Greenland) ice core
The time series of volcanically produced sulfate from the GISP2 ice core is used to develop a continuous record of explosive volcanism over the past 110,000 yr. We identified ∼850 volcanic signalsExpand
An AOGCM simulation of the climate response to a volcanic super-eruption
Volcanic ‘super-eruptions’ have been suggested to have significantly influenced the Earth’s climate, perhaps causing glaciations and impacting on the human population. Climatic changes following aExpand
Environmental impact of the 73 ka Toba super-eruption in South Asia
Abstract The cooling effects of historic volcanic eruptions on world climate are well known but the impacts of even bigger prehistoric eruptions are still shrouded in mystery. The eruption of TobaExpand
Did the Toba volcanic eruption of 74 ka B.P. produce widespread glaciation
[1] It has been suggested that the Toba volcanic eruption, approximately 74 ka B.P., was responsible for the extended cooling period and ice sheet advance immediately following it, but previousExpand
The ∼73 ka Toba super-eruption and its impact: History of a debate
Abstract Toba volcano in northern Sumatra is located at the intersection of two major tectonic lineaments in one of the most seismically active regions in the world, and its caldera is considered theExpand
Potential atmospheric impact of the Toba Mega‐Eruption ∼71,000 years ago
An {approx}6 year-long period of volcanic sulfate recorded in the GISP2 ice core about 71,000 {+-} 5000 years ago may provide detailed information on the atmospheric and climate impact in the TobaExpand
Volcanic Aerosol Records and Tephrochronology of the Summit, Greenland, Ice Cores
The recently collected Greenland Ice Sheet Project 2 (GISP2) and Greenland Ice Core Project ice cores from Summit, Greenland, provide lengthy and highly resolved records of the deposition of both theExpand
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


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
Perturbations to the global atmosphere associated with the El Chichon volcanic eruption of 1982
In terms of effects on the stratosphere, the 1982 eruption of the Mexican volcano El Chichon (17°N) is believed to have been one of the two or three greatest in the past century. In terms ofExpand
Triggering of volcanic pulses in the Campanian Area, south Italy, by periodic deep magma influx
Geochemical fluctuations through time of the eruptions originating from Ischia island and from the Phlegrean Fields in the Campanian area have been analyzed in order to determine the relationshipsExpand
Gas content, eruption rate and instabilities of eruption regime in silicic volcanoes
Abstract In silicic volcanoes, eruptions commonly begin with violent explosive phases and evolve towards a regime of dome formation. This transition is characterized by a decrease of gas volumeExpand
Effect of glacier loading/deloading on volcanism: postglacial volcanic production rate of the Dyngjufjöll area, central Iceland
Tephrochronological dating of postglacial volcanism in the Dyngjufjöll volcanic complex, a major spreading center in the Icelandic Rift Zone, indicates a high production rate in the millenniaExpand
Ice age as a trigger of active Quaternary volcanism and tectonism
Abstract The stress accumulation within the crust, caused by the surface mass redistribution associated with the glaciation-deglaciation cycle during the Quaternary, was numerically evaluated inExpand
Worldwide dispersal of ash and gases from earth's largest known eruption: Toba, Sumatra, 75 ka
The eruption of the Youngest Toba Tuff (YTT) occurred 75 ± 2 ka in North Sumatra (2°45′N, 98°45′E). The eruption produced at least 2800 km3 of dense rock equivalent (DRE) rhyolite magma (7 × 1018 g).Expand
Volcanic dust influence on glacier mass balance at high latitudes
EXPLOSIVE eruptions, which inject large quantities of volcanic dust into the earth's upper atmosphere, are believed to be important factors in climatic change. Theoretical considerations suggest thatExpand
Dimensions and dynamics of co-ignimbrite eruption columns
VERY powerful volcanic eruptions cannot always form classical Plinian eruption columns1–4. Instead, collapsing fountains may develop above the vent and shed pyroclastic flows which spread laterallyExpand
Global Increase in Quaternary Explosive Volcanism
The ash distribution in the deep-sea sections, which span the last 20 million years, indicates that there has been a much higher rate of explosive volcanism from both island arc and hot spot volcanoes during the last 2 million years. Expand
