This is a list of volcanoes that have had large explosive eruptions during the Holocene (since about 11,650 years Before Present), with a volcanic explosivity index (VEI) of 5 or higher, or a plume height of at least 30 km. 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.

<span class="mw-page-title-main">Supervolcano</span> Volcano that has had an eruption with a volcanic explosivity index (VEI) of 8

A supervolcano is a volcano that has had an eruption with a volcanic explosivity index (VEI) of 8, the largest recorded value on the index. This means the volume of deposits for such an eruption is greater than 1,000 cubic kilometers.

<span class="mw-page-title-main">Volcanic explosivity index</span> Predictive Qualitative scale for explosiveness of volcanic eruptions

The volcanic explosivity index (VEI) is a scale used to measure the size of explosive volcanic eruptions. It was devised by Christopher G. Newhall of the United States Geological Survey and Stephen Self in 1982.

<span class="mw-page-title-main">Eldgjá</span> Volcanic fissure and eruption in south Iceland

Eldgjá is a volcano and a canyon in Iceland. Eldgjá is part of the Katla volcano; it is a segment of a 40 kilometres (25 mi) long chain of volcanic craters and fissure vents that extends northeast away from Katla volcano almost to the Vatnajökull ice cap. This fissure experienced a major eruption around 939 CE, which was the largest effusive eruption in recent history. It covered about 780 square kilometres (300 sq mi) of land with 18.6 cubic kilometres (4.5 cu mi) of lava from two major lava flows.

<span class="mw-page-title-main">Plinian eruption</span> Type of volcanic eruption

Plinian eruptions or Vesuvian eruptions are volcanic eruptions marked by their similarity to the eruption of Mount Vesuvius in 79 AD, which destroyed the ancient Roman cities of Herculaneum and Pompeii. The eruption was described in a letter written by Pliny the Younger, after the death of his uncle Pliny the Elder.

<span class="mw-page-title-main">Mount Shishaldin</span> Symmetrical volcano in Alaska

Shishaldin Volcano, or Mount Shishaldin, is one of six active volcanoes on Unimak Island in eastern the Aleutian Islands of Alaska. It is the highest mountain peak of the Aleutian Islands, rising to a height of 9,373 ft above sea level. Shishaldin's magma supply is generated via flux melting above the Aleutian Trench, where the Pacific Plate subducts beneath the North American Plate. Due to its remote location and frequently inclement weather, the Alaska Volcano Observatory (AVO) monitors the volcano remotely via satellite and a seismic network deployed in 1997. Shishaldin is one of the most active volcanoes in the Aleutian Islands, with 40 confirmed eruptions in the last 11,700 years. Notably, Shishaldin produced a sub-Plinian eruption in 1999.

<span class="mw-page-title-main">Kambalny</span> Stratovolcano in southern Kamchatka

Kambalny is a stratovolcano located in the southern part of the Kamchatka Peninsula, Russia. It is the southernmost active volcano of Kamchatka. It has erupted mafic rocks. It has a summit crater as well as five cinder cones on its flanks which are the source of lava flows.

<span class="mw-page-title-main">Kuwae</span> Submarine caldera between the Epi and Tongoa islands in Vanuatu

Kuwae was a landmass that existed in the vicinity of Tongoa and was destroyed by volcanic eruption in fifteenth century, probably through caldera subsidence. The exact location of the caldera is debated. A submarine caldera, now known as Kuwae caldera that is located between the Epi and Tongoa islands, is a potential candidate. Kuwae caldera cuts through the flank of the Tavani Ruru volcano on Epi and the northwestern end of Tongoa. Another potential candidate is a proposed caldera between Tongoa and Tongariki.

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. Other volcanic eruptions are also listed.

<span class="mw-page-title-main">Te Pou Hawaiki</span> Former volcano in New Zealand

Te Pou Hawaiki is a volcano in the Auckland volcanic field in New Zealand. It was a small, low scoria cone south-east of Mount Eden that was quarried away in the early 20th century.

<span class="mw-page-title-main">946 eruption of Paektu Mountain</span> Major volcanic eruption in Korea

The 946 eruption of Paektu Mountain, a stratovolcano on the border of North Korea and China also known as Changbaishan, occurred in late 946 CE. This event is known as the Millennium Eruption or Tianchi eruption. It is one of the most powerful volcanic eruptions in recorded history; classified at least a VEI 6.

Laguna Amarga is a caldera and associated ignimbrite in the Andes of northwestern Argentina.

Dispersal index is a parameter in volcanology. The dispersal index was defined by George P. L. Walker in 1973 as the surface area covered by an ash or tephra fall, where the thickness is equal or more than 1/100 of the thickness of the fall at the vent. An eruption with a low dispersal index leaves most of its products close to the vent, forming a cone; an eruption with a high dispersal index forms thinner sheet-like deposits which extends to larger distances from the vent. A dispersal index of 500 square kilometres (190 sq mi) or more of coarse pumice is one proposed definition of a Plinian eruption. Likewise, a dispersal index of 50,000 square kilometres (19,000 sq mi) has been proposed as a cutoff for an ultraplinian eruption. The definition of 1/100 of the near-vent thickness was partially dictated by the fact that most tephra deposits are not well preserved at larger distances.

<span class="mw-page-title-main">Ticsani</span> Volcano in Peru

Ticsani is a volcano in Peru northwest of Moquegua and consists of two volcanoes that form a complex. "Old Ticsani" is a compound volcano that underwent a large collapse in the past and shed 15–30 cubic kilometres (3.6–7.2 cu mi) of mass down the Rio Tambo valley. Today an arcuate ridge remains of this edifice. "Modern Ticsani" is a complex of three lava domes which were emplaced during the Holocene. Two large eruptions took place during the Holocene, producing the so-called "Grey Ticsani" and "Brown Ticsani" deposits; the last eruption occurred after the 1600 eruption of neighbouring Huaynaputina. The volcano is seismically active and features active hot springs and fumaroles; since 2015 the volcano is monitored by the Peruvian government.

There are two large sulfate spikes caused by mystery volcanic eruptions in the mid-1400s: the 1452/1453 mystery eruption and 1458 mystery eruption. Before 2012, the date of 1458 sulfate spike was incorrectly assigned to be 1452 because previous ice core work had poor time resolution. The exact location of this eruption is uncertain, but possible candidates include the submerged caldera of Kuwae in the Coral Sea, Mount Reclus and Tofua caldera. The eruption is believed to have been VEI-7.

<span class="mw-page-title-main">Lunar Crater volcanic field</span> Volcanic field in Nye County, Nevada

Lunar Crater volcanic field is a volcanic field in Nye County, Nevada. It lies along the Reveille and Pancake Ranges and consists of over 200 vents, mostly small volcanic cones with associated lava flows but also several maars, including one maar named Lunar Crater. Some vents have been eroded so heavily that the structures underneath the volcanoes have been exposed. Lunar Crater itself has been used as a testing ground for Mars rovers and as training ground for astronauts.

Mount Rittmann is a volcano in Antarctica. Discovered in 1988–1989 by an Italian expedition, it was named after the volcanologist Alfred Rittmann (1893–1980). It features a 2 kilometres (1.2 mi) or 8 by 5 kilometres wide caldera which crops out from underneath the Aviator Glacier. The volcano was active during the Pliocene and into the Holocene, including large explosive eruptions; a major eruption occurred in 1254 CE and deposited tephra over much of Antarctica. Currently, the volcano is classified as dormant.

<span class="mw-page-title-main">Tierra Blanca Joven eruption</span> Catastrophic volcanic eruption of Lake Ilopango in El Salvador

The Tierra Blanca Joven eruption of Lake Ilopango was the largest volcanic eruption in El Salvador during historic times, and one of the largest volcanic events on Earth in the past 7,000 years, registering at 6 on the Volcanic explosivity index (VEI), and dating back to the mid 5th century A.D. The eruption produced between 37–82 km3 (8.9–19.7 cu mi) of ejecta. The date of the eruption has been constrained within 429–433 CE by identifying its signature volcanic ash in precision-dated ice cores sampled from Greenland, thus eliminating it as the cause of extreme weather events of 535–536.

<span class="mw-page-title-main">Cascade Volcanic Arc calderas</span>

The Cascade Volcanic Arc is a chain of volcanoes stretching from southern British Columbia down to northern California. Within the arc there is a variety of stratovolcanoes like Mount Rainier and broad shield volcanoes like Medicine Lake. But calderas are very rare in the Cascades, with very few forming over the 39 million year lifespan of the arc.
