Timeline of volcanism on Earth

This timeline of volcanism on Earth includes a list of major volcanic eruptions of approximately at least magnitude 6 on the Volcanic explosivity index or equivalent sulfur dioxide emission during the Quaternary period. Other volcanic eruptions are also listed.
Some eruptions cooled the global climate—inducing a volcanic winter—depending on the amount of sulfur dioxide emitted and the magnitude of the eruption. Before the present Holocene epoch, the criteria are less strict because of scarce data availability, partly since later eruptions have destroyed the evidence. Only some eruptions before the Neogene period are listed. Known large eruptions after the Paleogene period are listed, especially those relating to the Yellowstone hotspot, Santorini caldera, and the Taupō Volcanic Zone.
Active volcanoes such as Stromboli, Mount Etna and Kīlauea do not appear on this list, but some back-arc basin volcanoes that generated calderas do appear. Some dangerous volcanoes in "populated areas" appear many times: Santorini six times, and Yellowstone hotspot 21 times. The Bismarck volcanic arc, New Britain, and the Taupō Volcanic Zone, New Zealand, appear often too.
In addition to the events listed below, there are many examples of eruptions in the Holocene on the Kamchatka Peninsula, which are described in a supplemental table by Peter Ward.

Yellowstone Caldera, Henry's Fork Caldera, Island Park Caldera, Heise Volcanic Field all had Yellowstone hotspot as magma source.

Volcanic dimming

The global dimming through volcanism is quite independent of the eruption VEI. When sulfur dioxide reacts with water vapor, it creates sulfate ions, which are very reflective; ash aerosol on the other hand absorbs ultraviolet. Global cooling through volcanism is the sum of the influence of the global dimming and the influence of the high albedo of the deposited ash layer. The lower snow line and its higher albedo might prolong this cooling period. Bipolar comparison showed six sulfate events: Tambora, Cosigüina, Krakatoa, Agung, and El Chichón, and the 1808 mystery eruption. And the atmospheric transmission of direct solar radiation data from the Mauna Loa Observatory, Hawaii detected only five eruptions:

June 11, 2009, Sarychev Peak, Kuril Islands, 400 tons of tephra, VEI 4
*
June 12–15, 1991, Mount Pinatubo, Philippines, 11,000 ±0.5 tons of tephra, VEI 6
*Global cooling: 0.5 °C,
March 28, 1982, El Chichón, Mexico, 2,300 tons of tephra, VEI 5
*
October 10, 1974, Volcán de Fuego, Guatemala, 400 tons of tephra, VEI 4
*
February 18, 1963, Mount Agung, Lesser Sunda Islands, 100 tons of lava, more than 1,000 tons of tephra, VEI 5
*Northern Hemisphere cooling: 0.3 °C,

But very large sulfur dioxide emissions overdrive the oxidizing capacity of the atmosphere. Carbon monoxide's and methane's concentration goes up, global temperature goes up, ocean's temperature goes up, and ocean's carbon dioxide solubility goes down.
