Decade Volcano in the context of "Mount Teide"

Santorini caldera is a large, mostly submerged caldera, located in the southern Aegean Sea, 120 kilometers north of Crete in Greece. Visible above water is the circular Santorini island group, consisting of Santorini (known as Thera in antiquity), the main island, Therasia and Aspronisi at the periphery, and the Kameni islands at the center. It has been designated a Decade Volcano.

Koryaksky or Koryakskaya Sopka (Russian: Коря́кская со́пка) is an active volcano on the Kamchatka Peninsula in the Russian Far East. It lies within sight of Kamchatka Krai's administrative center, Petropavlovsk-Kamchatsky. Together with neighbouring Avachinsky, it is considered a Decade Volcano, worthy of particular study in light of its history of explosive eruptions and proximity to populated areas.

Mount Rainier (/reɪ.ˈnɪər/ ray-NEER), also known as Tahoma, is a large active stratovolcano in the Cascade Range of the Pacific Northwest in the United States. The mountain is located in Mount Rainier National Park about 59 miles (95 km) south-southeast of Seattle. At around 14,000 feet (4,400 m) it is the highest mountain in the U.S. state of Washington, the most topographically prominent mountain in the contiguous United States, and the tallest in the Cascade Volcanic Arc.

Due to its high probability of an eruption in the near future and proximity to a major urban area, Mount Rainier is considered one of the most dangerous volcanoes in the world, and it is on the Decade Volcano list. The large amount of glacial ice means that Mount Rainier could produce massive lahars that could threaten the entire Puyallup River valley and other river valleys draining Mount Rainier, including the Carbon, White, Nisqually, and Cowlitz (above Riffe Lake). According to the United States Geological Survey's 2008 report, "about 80,000 people and their homes are at risk in Mount Rainier's lahar-hazard zones."

Teide (Spanish: El Teide) or Mount Teide (Pico del Teide, pronounced [ˈpiko ðel ˈtejðe]; 'Peak of Teide') is a volcano on Tenerife in the Canary Islands. Its summit (at 3,715 m (12,188 ft)) is the highest point in the Canary Islands and the highest point above sea level in the islands of the Atlantic. If measured from the ocean floor, its height of 7,500 m (24,600 ft) makes Teide the third-highest volcano in the world; UNESCO and NASA rank it as Earth's third-tallest volcanic structure. Teide's elevation above sea level makes Tenerife the tenth highest island in the world.

Teide started forming 170,000 years ago due to volcanic activity following a catastrophic landslide. Teide's base is situated in Las Cañadas crater (the remains of an older, eroded, extinct volcano) at a height of around 2,190 m (7,190 ft) above sea level. Teide is an active volcano: its most recent eruption occurred in late 1909 from the El Chinyero vent on the northwestern Santiago rift. The United Nations Committee for Disaster Mitigation designated Teide a Decade Volcano because of its history of destructive eruptions and its proximity to several large towns, of which the closest are Garachico, Icod de los Vinos and Puerto de la Cruz. Teide, Pico Viejo and Montaña Blanca form the Central Volcanic Complex of Tenerife.

Taal Volcano (IPA: [taʔal]; Tagalog: Bulkang Taal) is a large caldera filled by Taal Lake in the Philippines. Located in the province of Batangas about 50 kilometers (31 mi) south of Manila, the volcano is the second most active volcano in the country with 39 recorded historical eruptions, all of which were concentrated on Volcano Island, near the middle of Taal Lake. The caldera was formed by prehistoric eruptions between <670,000 and <6,000 years ago. The cones Batulao, Maculod, Sugnay are remnants of the early pre caldera Taal system with Batulao being the earliest known cone.

Taal Volcano has had several violent eruptions in the past, causing deaths on the island and the populated areas surrounding the lake, with an overall death toll of about 6,000. Because of its proximity to populated areas and its eruptive history, the volcano was designated a Decade Volcano, worthy of close study to prevent future natural disasters. The site was declared National Geological Monument in 1998 and a national park in 2018.

Avachinsky (also known as Avacha or Avacha Volcano or Avachinskaya Sopka) (Russian: Авачинская сопка, Авача) is an active stratovolcano in Russia. It is situated on the Kamchatka Peninsula in the Russian Far East. Avachinsky lies within sight of Petropavlovsk-Kamchatsky, the capital of Kamchatka Krai. Together with neighbouring Koryaksky volcano, it is considered a Decade Volcano, worthy of particular study in light of its history of explosive eruptions and proximity to populated areas.

Avachinsky's last eruption occurred in 2008. This eruption was relatively small in comparison to the volcano's major Volcanic Explosivity Index 4 eruption in 1945.
