Saint Kitts and Nevis is a twin island country with a total landmass of just 270 square kilometres (104 sq mi). The island of St. Kitts, the larger of the two, is 180 square kilometres (68 sq mi) in size and is located at latitude 17.30 N, and longitude 62.80 W. Nevis is 93 square kilometres (36 sq mi) and located at latitude 17.10 N, longitude 62.35 W, approximately 3 km south-east of St. Kitts. The islands are about one-third of the way from Puerto Rico to Trinidad and Tobago. The islands are volcanic and mountainous.
Saint Kitts, officially Saint Christopher, is an island in the West Indies. The west side of the island borders the Caribbean Sea, and the eastern coast faces the Atlantic Ocean. Saint Kitts and the neighbouring island of Nevis constitute one country: the Federation of Saint Kitts and Nevis. Saint Kitts and Nevis are separated by a shallow 3-kilometre (2 mi) channel known as "The Narrows".
Mount Shasta is a potentially active volcano at the southern end of the Cascade Range in Siskiyou County, California. At an elevation of 14,179 ft (4,322 m), it is the second-highest peak in the Cascades and the fifth-highest in the state. Mount Shasta has an estimated volume of 85 cubic miles, which makes it the most voluminous stratovolcano in the Cascade Volcanic Arc. The mountain and surrounding area are part of the Shasta–Trinity National Forest.
Arenal Volcano is an active andesitic stratovolcano in north-western Costa Rica around 90 km (56 mi) northwest of San José, in the province of Alajuela, canton of San Carlos, and district of La Fortuna. The Arenal volcano measures at least 1,633 metres (5,358 ft) high. It is conically shaped with a crater 140 metres (460 ft) in diameter. Geologically, Arenal is considered a young volcano and it is estimated to be less than 7,500 years old.

Mount Kerinci, also spelled Kerintji, is an active stratovolcano and the highest mountain in Sumatra, Indonesia. At 12,484 ft (3,805 m) above sea level, it provides Sumatra with the fifth-highest maximum elevation of any island in the world. It is surrounded by the lush forest of Kerinci Seblat National Park, home to several endangered species including the Sumatran tiger. Mount Kerinci is ranked 32nd by topographic isolation.
Mount Spurr (Dena'ina: K'idazq'eni) is a stratovolcano in the Aleutian Arc of Alaska, named after United States Geological Survey geologist and explorer Josiah Edward Spurr, who led an expedition to the area in 1898.

Mount Scenery is a dormant volcano in the Caribbean Netherlands. Its lava dome forms the summit of the Saba island stratovolcano. At an elevation of 887 m (2,910 ft), it is the highest point in both the Kingdom of the Netherlands, and, since the dissolution of the Netherlands Antilles on 10 October 2010, the highest point in the Netherlands proper.
Simushir, meaning Large Island in Ainu, is an uninhabited volcanic island near the center of the Kuril Islands chain in the Sea of Okhotsk in the northwest Pacific Ocean. It was formerly known as Marikan.
Mount Sinabung is a Pleistocene-to-Holocene stratovolcano of andesite and dacite in the Karo plateau of Karo Regency, North Sumatra, Indonesia, 40 kilometres (25 mi) from the Lake Toba supervolcano. Many old lava flows are on its flanks and the last known eruption, before recent times, occurred 1200 years before present, between 740 - 880 CE. Solfataric activities were last observed at the summit in 1912; recent documented events include an eruption in the early hours of 29 August 2010 and eruptions in September and November 2013, January, February and October 2014. The volcano has recently claimed the life of at least 23 people in a number of events since 2014. Between 2013 and 2014, the alert for a major event was increased with no significant activity. On 2 June 2015, the alert was again increased, and on 26 June 2015, at least 10,000 people were evacuated, fearing a major eruption. The long eruption of Mount Sinabung is similar to that of Mount Unzen in Japan, which erupted for five years after lying dormant for 400 years. A major eruption began on 10 August 2020.
The volcano Tacaná is the second highest peak in Central America at 4,060 metres (13,320 ft), located in the Sierra Madre de Chiapas of northern Guatemala and southern Mexico. It is also known in Mexico as Volcán Tacina.
Nevis Peak is a potentially active volcano which is located in the centre of the island of Nevis of the Federation of Saint Kitts and Nevis in the West Indies. The stratovolcano rises to a height of 985 metres (3,232 ft) and is the highest point on the island. There have been no eruptions since prehistory, but there are active fumaroles and hot springs on the coastal slopes of the island, and these represent low-level volcanic activity.
Olivees Mountain is the third highest peak on the island of Saint Kitts in the Caribbean.
The following outline is provided as an overview of and topical guide to Saint Kitts and Nevis:
La Soufrière, a stratovolcano on the Caribbean island of Saint Vincent in Saint Vincent and the Grenadines, began an effusive eruption on 27 December 2020. On 9 April 2021 there was an explosive eruption, and the volcano "continued to erupt explosively" over the following days, with pyroclastic flows. The activity pattern of the eruption was comparable to that of the event that occurred in 1902, which had a Volcanic Explosivity Index (VEI) of 4. The volcano is known to have erupted 23 times in the last 4,000 years, and had been dormant since 1979.
