Etna in Italy is sometimes called the oldest active volcano because it has the longest historic record of eruptions. It has erupted 190 times in the last 3,500 years.
It is now obvious that volcanoes are erupting at a faster pace, not only around the ring of fire but around the entire globe. An extinct volcano by definition is dead volcano, which has not erupted in the last 10,000 years and is not expected to ever erupt again.
It is a volcano that has been dormant since its last eruption, in 1707, but is still generally classified as active by geologists. The mountain is the major feature of Fuji-Hakone-Izu National Park (1936), and it is at the centre of a UNESCO World Heritage site designated in 2013.
There actually are simple Existing volcanos that have been dormant may indeed send up ash or smoke indicating a resumption of activity, but that “renewed activity” may just be that - or it may lead to more. When Mt St Helens woke up. It sent up smoke and ash plumes for several months before it exploded.
Answer and Explanation: There are millions of inactive volcanoes in the world. The exact number of volcanoes has not ever been counted.
Mount Arayat is a potentially active basaltic volcano on Luzon Island, Philippines, rising to a height of 1,026 metres (3,366 ft). There are no historical records of eruption in Arayat and the only dated rocks are 530- and 650-thousand-year-old basalts predating the collapse and formation of the lava dome.
Is Yellowstone's volcano still active? Yes. The park's many hydrothermal features attest to the heat still beneath this area. Earthquakes—700 to 3,000 per year— also reveal activity below ground.
A dormant volcano is an active volcano that is not erupting, but supposed to erupt again. An extinct volcano has not had an eruption for at least 10,000 years and is not expected to erupt again in a comparable time scale of the future.
The biggest danger is that it will re-awaken. It may undergo an explosive eruption. People may have become complacent if the dormancy has lasted more than one generation (in the case of Vesuvius in 79 CE, the volcano had been dormant for about 250 years; people weren't even aware it was a volcano)
Scientists believe the magma chambers—or reservoirs of molten rock—under dormant volcanoes are filled with sticky, viscous mush. For a volcano to "wake up," this mush needs to be thoroughly heated by fresh, hot magma rising up from the deep Earth.
If a volcano has erupted since the last Ice Age—in the last 10,000 years or so—and is still showing activity like lava and ash flows or gas emissions, it's considered to be active. If a volcano hasn't erupted in the last 10,000 years, but scientists think it will erupt again, it's considered dormant.
If your volcano is making noise or popping off, then its active. If your volcano has erupted in the past but right now is quiet, it is likely dormant. If your volcano hasn't erupted in over a million years, you have yourself an ex-volcano.
A dormant volcano would then be one that hasn't erupted in the past 10,000 years, but which is expected to erupt again. An extinct volcano would be one that nobody expects to ever erupt again.
Volcanoes go dormant because magma from the Earth's mantle can no longer reach the volcano. For example, in Hawaii, the line of islands are slowly moving to the northwest. This can also happen when the angle of subduction changes and magma begins to rise through the mantle in a different location.
SLEEPING GIANT Bolshaya Udina, a volcano on Russia's Kamchatka Peninsula, has long been inactive. Some scientists suggest the volcano is waking up, based on nearby seismic activity. But others say those rumblings may be linked to active volcanoes in the region.
Scientists believe the magma chambers—or reservoirs of molten rock—under dormant volcanoes are filled with sticky, viscous mush. According to current theory, it would take several hundred or perhaps a thousand years for the heat to distribute through the chamber and make the magma fluid enough to erupt.
There are a number of extinct volcanoes in Ireland these include Slieve Gullion in County Armagh, Croghan Hill in County Offaly, Mount Slemish in County Antrim, Lambay Island in Dublin and Loch Na Fooey in County Galway. These volcanoes are all extinct with the last eruption was approximately 60 million years ago.
Although in a dormant phase at present, Vesuvius is an extremely active volcano and particular for its unusually varied style of activity: it ranges from Hawaiian-style emission of very liquid lava, extreme lava fountains, lava lakes and lava flows, over Strombolian and Vulcanian eruptions to violently explosive,
There are about 300 volcanoes in the Philippines. Twenty-two (22) of these are active while the larger percentage remains dormant as of the record. The majority of the active volcanoes are located in the island of Luzon. The six most active volcanoes are Mayon, Hibok-Hibok, Pinatubo, Taal, Kanlaon and Bulusan.
Called Tamu Massif, this enormous dormant or inactive volcano is located within the huge underwater mountain range called Shatsky Rise formation about 1609 kilometers east of Japan.

As of 2012, PHIVOLCS lists 23 volcanoes as active in the Philippines, 21 of which have historical eruptions; one,
Cabalian, which is a strongly fumarolic volcano; and one, Leonard Kniaseff, which was active 1,800 years ago (C14).

How many active volcanoes are there on Earth? There are about 1,500 potentially active volcanoes worldwide, aside from the continuous belts of volcanoes on the ocean floor at spreading centers like the Mid-Atlantic Ridge. About 500 of those 1,500 volcanoes have erupted in historical time.
