Indian Peak-Caliente Caldera Complex. 4,400. Formed the White Rock Caldera, one of the largest eruptions of the Mid-Tertiary Ignimbrite flareup.
This is a list of volcanic eruptions in the 21st century with a volcanic explosivity index (VEI) of 4 or higher, and smaller eruptions that resulted in fatalities, significant damage or disruptions. As of 26 October 2024, the largest volcanic eruption of the 21st century is the 2022 Hunga Tonga–Hunga Haʻapai eruption and tsunami, and the ...
World map of active volcanoes and plate boundaries Kīlauea's lava entering the sea Lava flows at Holuhraun, Iceland, September 2014. An active volcano is a volcano that has erupted during the Holocene (the current geologic epoch that began approximately 11,700 years ago), is currently erupting, or has the potential to erupt in the future.

Eruption. Oruanui eruption impact North Island in terms of approximate 10cm ash deposit (white shading) and approximate ignimbrite from pyroclastic flow (yellow shading). [2]: 529 The central red area is the Oruanui caldera with surrounding collapse crater in lighter red. It is superimposed on present day New Zealand although at the time New ...
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. The process that forms volcanoes is called volcanism. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and because most of Earth ...
List of large volcanic eruptions. Satellite images of the 15 January 2022 eruption of Hunga Tonga-Hunga Haʻapai. This is a sortable list of large eruptions that occurred between 11.7 Ka and 450+ Ma. Uncertainties as to dates and tephra volumes are not restated, and references are not repeated. The inclusion criteria here only covers entries ...
Wah Wah Springs Caldera is a supervolcanic eruption remnant discovered in 2013 in Utah. It released 5,500 to 5,900 cubic kilometres (1,300 to 1,400 cu mi) of tephra, as the Wah Wah Springs Tuff, about 30.06 million years ago in the early Oligocene. It is the largest of the Indian Peak-Caliente Caldera Complex, and includes flows over 500 m ...
