To date, there have been no eruptions with a confirmed VEI of 8 in the Holocene; and only a few VEI-7 eruptions are thought to have occurred during this time: the most recent was the 1815 eruption of Mount Tambora. This is not a complete list.
The only semi-recent example was the 1815 eruption of Mount Tambora, which led to worldwide cooling and agricultural failures and caused 1816 to become known as the "year without a summer."
