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 (VEI) or equivalent sulfur dioxide emission during the Quaternary period (from 2.58 Mya to the present). 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 (from 23 Mya to 2.58 Mya) are listed. Known large eruptions after the Paleogene period (from 66 Mya to 23 Mya) 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.

Large Quaternary eruptions

The Holocene epoch begins 11,700 years BP (10,000 <sup>14</sup>C years ago).

1000–2000 AD

Overview of Common Era

This is a sortable summary of 27 major eruptions in the last 2000 years with VEI ≥6, implying an average of about 1.3 per century. The count does not include the notable VEI 5 eruptions of Mount St. Helens and Mount Vesuvius. Date uncertainties, tephra volumes, and references are also not included.

Note: Caldera names tend to change over time. For example, Ōkataina Caldera, Haroharo Caldera, Haroharo volcanic complex, and Tarawera volcanic complex all had the same magma source in the Taupō Volcanic Zone. Yellowstone Caldera, Henry's Fork Caldera, Island Park Caldera, Heise Volcanic Field all had Yellowstone hotspot as magma source.

Earlier Quaternary eruptions

2.588 ± 0.005 million years BP, the Quaternary period and Pleistocene epoch begin.

Large Neogene eruptions

Pliocene eruptions

Approximately 5.332&nbsp;million years BP, the Pliocene epoch begins. Most eruptions before the Quaternary period have an unknown VEI.

Miocene eruptions

Approximately 23.03&nbsp;million years BP, the Neogene period and Miocene epoch begin.

Volcanism before the Neogene

Notes

Volcanic explosivity index (VEI)

&nbsp; &nbsp; &nbsp; &nbsp;

Volcanic dimming

The global dimming through volcanism (ash aerosol and sulfur dioxide) is quite independent of the eruption VEI. When sulfur dioxide (boiling point at standard state: -10&nbsp;°C) reacts with water vapor, it creates sulfate ions (the precursors to sulfuric acid), 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 (1815), Cosigüina (1835), Krakatoa (1883), Agung (1963), and El Chichón (1982), and the 1808 mystery eruption. And the atmospheric transmission of direct solar radiation data from the Mauna Loa Observatory (MLO), Hawaii (19°32'N) detected only five eruptions:

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