During 2023, 77 volcanoes erupted, 245.3 square kilometers of land were scorched via either pyroclastic flows and lava flows, and a brand new volcanic island was born. This video discusses the most noteworthy stories on volcanoes of 2023 and also mentions the largest explosive and largest effusive volcanic eruptions of 2023.

Note: This video's thumbnail image displays a photograph of the 1992 eruption of Mount Spurr. Mount Spurr did not erupt in 2023 and is currently not expected to erupt anytime soon. However, this image is being used to show what Shiveluch's plinian eruption on April 11th of 2023 might have looked like in Russia.
