The Volcanic Explosivity Index (VEI) is a relative measure of the explosiveness of volcanic eruptions. It was devised by Chris Newhall of the United States Geological Survey and Stephen Self at the University of Hawaii in 1982.
An active volcano is a volcano which is either erupting or is likely to erupt in the future. An active volcano which is not currently erupting is known as a dormant volcano.
Mount Iliamna is a glacier-covered stratovolcano in the largely volcanic Aleutian Range in southwest Alaska. Located in the Chigmit Mountain subrange in Lake Clark National Park and Preserve, the 10,016-foot (3,053 m) volcano lies approximately 134 miles (215 km) southwest of Anchorage on the west side of lower Cook Inlet. It is the 25th most prominent peak in the United States.
Reventador is an active stratovolcano which lies in the eastern Andes of Ecuador. It lies in a remote area of the national park of the same name, which is Spanish for "exploder". Since 1541, it has erupted over 25 times, although its isolated location means that many of its eruptions have gone unreported.
Semeru, or Mount Semeru, is an active volcano in East Java, Indonesia. It is located in the subduction zone, where the Indo-Australia plate subducts under the Eurasia plate. It is the highest mountain on the island of Java. This stratovolcano is also known as Mahameru, meaning "The Great Mountain" in Sanskrit. The name derived from the Hindu cosmology's mountain of Meru or Sumeru, the abode of gods.
Peléan eruptions are a type of volcanic eruption. They can occur when viscous magma, typically of rhyolitic or andesitic type, is involved, and share some similarities with Vulcanian eruptions. The most important characteristic of a Peléan eruption is the presence of a glowing avalanche of hot volcanic ash, called a pyroclastic flow. Formation of lava domes is another characteristic. Short flows of ash or creation of pumice cones may be observed as well.
Lava lakes are large volumes of molten lava, usually basaltic, contained in a volcanic vent, crater, or broad depression. The term is used to describe both lava lakes that are wholly or partly molten and those that are solidified.
Ebeko is a highly active somma volcano located on the northern end of Paramushir Island, Kuril Islands, Russia. It is one of the most active volcanoes of the Kuril Islands. Eleven eruptions have been recorded between 1793 and 1991. Most of the eruptions are small (VEI=1) with the exception of the 1859 eruption (VEI=3). Most eruptions were phreatic and explosive.
Calbuco is a stratovolcano in southern Chile, located southeast of Llanquihue Lake and northwest of Chapo Lake, in the Los Lagos Region, and close to the cities of Puerto Varas and Puerto Montt. With an elevation of 2,015 meters above sea level, the volcano and the surrounding area are protected within the Llanquihue National Reserve.
Telica is a stratovolcano, one of several volcanoes of the Nicaraguan volcanic front. It is located in Telica municipality, in the León department of Nicaragua. One of Nicaragua's most active volcanoes, Telica has erupted frequently, and ash from those frequent eruptions keeps the slopes of its cone bare of vegetation.
The Smithsonian Institution's Global Volcanism Program (GVP) documents Earth's volcanoes and their eruptive history over the past 10,000 years. The GVP reports on current eruptions from around the world as well as maintaining a database repository on active volcanoes and their eruptions. In this way, a global context for the planet's active volcanism is presented. Smithsonian reporting on current volcanic activity dates back to 1968, with the Center for Short-Lived Phenomena (CSLP). The GVP is housed in the Department of Mineral Sciences, part of the National Museum of Natural History, on the National Mall in Washington, D.C.
The Jolo Group of Volcanoes, more commonly referred to as the Jolo Group, are an active group of volcanoes in the island of Jolo in Southern Philippines. The Global Volcanism Program lists Jolo as one of the active volcanoes in the Philippines while the Philippine Institute of Volcanology and Seismology (PHIVOLCS) collectively list the group as Bud Dajo, one of the cinder cones on the island.
