An active volcano is a volcano that has erupted during the Holocene (the current geologic epoch that began approximately 11,700 years ago), is currently erupting, or has the potential to erupt in the future. [1] A volcano that is not currently erupting but could erupt in the future is known as a dormant volcano. [1]
Volcanoes vary greatly in their level of activity, with individual volcanic systems having an eruption recurrence ranging from several times a year to once in tens of thousands of years. [61] Volcanoes are informally described as erupting, active, dormant, or extinct, but the definitions of these terms are not entirely uniform amongst ...
The volcano was dormant from 1977 then showed signs of unrest since 1991 with strong seismic activity and ground-fracturing events, as well as the formation of small mud geysers on parts of the island. An eruption occurred in January 2020. Kanlaon Volcano, the most active volcano in the central Philippines, has erupted 25 times since 1866 ...
Although dormant, Santorini is an active volcano. Numerous minor and medium-sized, mainly effusive, eruptions have built the dark-colored lava shields of Nea and Palea Kameni inside the caldera. Their last eruption was in 1950, and now only fumarolic activity, primarily inside the recently active craters, takes place. [2]

Mount Kilimanjaro (/ ˌkɪlɪmənˈdʒɑːroʊ /) [3] is a dormant volcano in Tanzania. It is the highest mountain in Africa and the highest free-standing mountain above sea level in the world: 5,895 m (19,341 ft) above sea level and 4,900 m (16,100 ft) above its plateau base. It is also the highest volcano in the Eastern Hemisphere and the ...
The Cascade volcanoes have had more than 100 eruptions over the past few thousand years, many of them explosive eruptions. [21] However, certain Cascade volcanoes can be dormant for hundreds or thousands of years between eruptions, and therefore the great risk caused by volcanic activity in the regions is not always readily apparent.
This list of shield volcanoes includes active, dormant and extinct shield volcanoes.Shield volcanoes are one of the three types [specify] of volcanoes. They have a short cone shape, and have basaltic lava which means the lava has low viscosity (viscosity is a measure of the ability for a liquid to flow)
