There are 83 inactive and active volcanoes within the Sierra Madre range, including 11 in Mexico, 37 in Guatemala, 23 in El Salvador, 25 in Nicaragua, and 3 in northwestern Costa Rica.

Active volcanoes in the region include Mount Garibaldi, Mount Baker, Mount Rainier, Mount St. Helens, Mount Adams, Mount Hood, Mount Meager, Mount Jefferson, Mount Shasta, Lassen Peak and Glacier Peak.

Due to the presence of several active geologic faults and the Central America Volcanic Arc, seismic activity in the region, such as volcanic eruptions and earthquakes, is high

The Krakatoa eruption drastically altered the topography of the strait, with as much as 18-21 km3 of ignimbrite being deposited over an area of 1.1 million km2 around the volcano.

Between Katha and Mandalay, the course of the river is remarkably straight, flowing almost due south, except near Kabwet, where a sheet of lava has caused the river to bend sharply westward.

The Siberian Traps were formed by one of the largest-known volcanic events of the last 251 million years of Earth's geological history.

Most Polynesian islands and archipelagos, including the Hawaiian Islands and Samoa, are composed of volcanic islands built by hotspots (volcanoes).

Obduction has scraped accumulated rock onto the North American plate, islands and intrusions have been formed by volcanism, and the local crust has become deformed in other ways.

Geologically, the archipelago is one of the most active volcanic regions in the world, producing many volcanoes, especially in Java, Sumatra, and the Lesser Sunda Islands region, where most volcanoes over 3,000 m (9,800 ft) are situated.

Geologically, the archipelago is one of the most active volcanic regions in the world.

Other Indian Ocean islands, like the Comoros and Mascarene Islands, are volcanic islands that formed more recently.

Graham Land's creation was volcanic and happened over 200 million years ago.

Various volcanoes with activity in the Quaternary exist in the islands.

These are landmasses that are typically formed due to volcanic activity.

Volcanism along western Graham Land dates from the Cretaceous to present times, and outcrops are found along the Gerlache Strait, the Lemaire Channel, Argentine Islands, and Adelaide Island.

The relationship between Vatnajökull and the volcanoes beneath it is classified as glaciovolcanism.

Bataan is divided by two mountain groups of volcanic origins.

Peninsulas can be formed by continental drift, glacial erosion, glacial meltwater, glacial deposition, marine sediment, marine transgressions, volcanoes, divergent boundaries or river sedimentation.

A volcanic plateau is a plateau produced by volcanic activity.

A volcanic crater is an approximately circular depression in the ground caused by volcanic activity.

A volcanic eruption blocked its original outlet in prehistoric times.

Macaronesia (Portuguese: Macaronésia; Spanish: Macaronesia) is a collection of four volcanic archipelagos in the North Atlantic Ocean, off the coast of North Africa and Europe.

A cinder cone or scoria cone is a steep, conical landform of loose pyroclastic fragments, such as volcanic ash, clinkers, or scoria, that has been built around a volcanic vent.

A stratovolcano, also known as a composite volcano, is a typically conical volcano built up by many alternating layers (strata) of hardened lava and tephra.

Plateaus can be formed by a number of processes, including upwelling of volcanic magma, extrusion of lava, and erosion by water and glaciers.

It is a dormant stratovolcano rising 5,642 m (18,510 ft) above sea level, and is the highest volcano in Eurasia, as well as the tenth-most prominent peak in the world.

Seamounts are typically formed from extinct volcanoes that rise abruptly and are usually found rising from the seafloor to 100-4,000 m (330-13,120 ft) in height.

In marine geology, a guyot (), also called a tablemount, is an isolated underwater volcanic mountain (seamount) with a flat top more than 200 m (660 ft) below the surface of the sea.

It is the highest mountain in Japan, the second-highest volcano on any Asian island (after Mount Kerinci on the Indonesian island of Sumatra), and the seventh-highest peak of an island on Earth.

Mauna Kea (, Hawaiian: [ˈmɐwnə ˈkɛjə]; abbreviation for Mauna a Wākea, 'White Mountain') is a dormant shield volcano on the island of Hawaiʻi.

The Deccan Traps in the northwest were formed by multiple layers of igneous rock deposited by basaltic lava flows following a massive volcanic eruption occurred at the end of the Cretaceous period (66 mya).

Citlaltépetl (from Náhuatl citlal(in) = star, and tepētl = mountain), otherwise known as Pico de Orizaba, is an active volcano and the highest volcano in North America, as well as the highest mountain in Mexico and third highest peak in North America, after Denali of the United States and Mount Logan of Canada.

Nevado Ojos del Salado (Spanish pronunciation: [ˈoxos ðel saˈlaðo] ) is a dormant complex volcano in the Andes on the Argentina-Chile border.

Generally, geyser field sites are located near active volcanic areas, and the geyser effect is due to the proximity of magma.

According to Charles Darwin's subsidence model, the formation of an atoll is explained by the sinking of a volcanic island around which a coral fringing reef has formed.

A volcano is a vent or fissure in the crust of a planetary-mass object that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface.

A fumarole (; also spelled fumerole) is a vent through the surface of Earth or another terrestrial planet from which hot volcanic gases and vapors are emitted, without any accompanying liquids or solids.

Easter Island is a volcanic island, consisting mainly of three extinct coalesced volcanoes

Such mountain systems have a complex structure, which is usually the result of folding and faulting accompanied by volcanic activity.
