  2. Year Without a Summer - Wikipedia

    en.wikipedia.org/wiki/Year_Without_a_Summer

    This eruption was the largest in at least 1,300 years (after the hypothesized eruption causing the volcanic winter of 536); its effect on the climate may have been exacerbated by the 1814 eruption of Mayon in the Philippines. The significant amount of volcanic ash and gases released into the atmosphere blocked sunlight, leading to global cooling.

  3. Volcanic winter of 536 - Wikipedia

    en.wikipedia.org/wiki/Volcanic_winter_of_536

    The lingering effect of the volcanic winter of 536 was augmented in 539–540, when another volcanic eruption caused summer temperatures to decline as much as 2.7 °C (4.9 °F) below normal in Europe. [2] There is evidence of still another volcanic eruption in 547 which would have extended the cool period.

  4. Volcanic winter - Wikipedia

    en.wikipedia.org/wiki/Volcanic_winter

    The conversion of sulfur dioxide to sulfuric acid, which condenses rapidly in the stratosphere to form fine sulfate aerosols. A volcanic winter is a reduction in global temperatures caused by droplets of sulfuric acid obscuring the Sun and raising Earth's albedo (increasing the reflection of solar radiation) after a large, sulfur-rich, particularly explosive volcanic eruption.

  5. 1815 eruption of Mount Tambora - Wikipedia

    Their estimate was 11,000 deaths from direct volcanic effects and 49,000 by post-eruption famine and epidemic diseases. [20] Oppenheimer wrote that there were at least 71,000 deaths in total. [4] Reid has estimated that 100,000 people on Sumbawa, Bali, and other locations died from the direct and indirect effects of the eruption. [21]

  6. Siberian Traps - Wikipedia

    en.wikipedia.org/wiki/Siberian_Traps

    It has been suggested that, as the Earth's lithospheric plates moved over the mantle plume (the Iceland plume), the plume had earlier produced the Viluy Traps to the east, then the Siberian Traps in the Permian and Triassic periods, and later going on to produce volcanic activity on the floor of the Arctic Ocean in the Jurassic and Cretaceous ...

    On June 15, 1991, a rumbling Mount Pinatubo grew and grew until it exploded in the biggest volcanic eruption on Earth in 100 years. Super-pressurized, gas-charged magma burst through and a cloud ...

    Large igneous province (LIP) eruptions [23] from the Siberian Traps, [24] an impact event (the Wilkes Land Crater), [25] an Anoxic event, [26] an Ice age, [27] or other possible causes End-Capitanian extinction event: 260 Ma: Volcanism from the Emeishan Traps, [28] resulting in global cooling and other effects Olson's Extinction: 270 Ma Unknown.

  9. Alvarez hypothesis - Wikipedia

    en.wikipedia.org/wiki/Alvarez_hypothesis

    This theory proposes that the impact itself instigated the most intense period of Deccan eruptions, both of which had devastating effects contributing to the K-Pg extinction. [14] [21] [20] Renne and Richards calculated that the Chixculub impact was capable of producing seismic activity strong enough to initiate volcanic eruptions.
