Kliuchevskoi Volcano-Russia

"Kliuchevskoi is one of the most active volcanoes of the Kamchatka Peninsula in Far Eastern Russia. The volcano has had more than 80 eruptions since 1697. On September 15, 1994, gas and ash shot out of the crater, creating a column 2 km high. Over the next two weeks the eruption continued, and on 1 October a giant eruption occurred. A cloud of ash rose 15-20 km above the volcano. A picture taken by a weather satellite showed that the ash cloud extended 565 km to the SE, and that it was moving at about 140 km/hr (~85 mile/hr)! While ash was being blown out the top of the volcano, new rivers of lava flowed down its flanks. During the next three days the eruption stopped, and only steam rose above the crater."

Mount Tolbachik

"The massive Tolbachik basaltic volcano is located at the southern end of the dominantly andesitic Kliuchevskaya volcano group. The Tolbachik massif is composed of two overlapping, but morphologically dissimilar volcanoes. The flat-topped Plosky Tolbachik shield volcano with its nested Holocene Hawaiian-type calderas up to 3 km in diameter is located east of the older and higher sharp-topped Ostry Tolbachik stratovolcano. The summit caldera at Plosky Tolbachik was formed in association with major lava effusion about 6500 years ago and simultaneously with a major southward-directed sector collapse of Ostry Tolbachik volcano. Lengthy rift zones extending NE and SSW of the volcano have erupted voluminous basaltic lava flows during the Holocene, with activity during the past two thousand years being confined to the narrow axial zone of the rifts. The 1975-76 eruption originating from the SSW-flank fissure system and the summit was the largest historical basaltic eruption in Kamchatka."

Mount Fuji

"Mount Fuji (富士山, Fuji-san) is the highest mountain in Japan at 3,776 m (12,388 ft). Along with Mount Tate and Mount Haku, it is one of Japan's Three Holy Mountains. An active volcano that last erupted in 1707–08, Mount Fuji straddles the boundary of Shizuoka and Yamanashi prefectures just west of Tokyo, from which it can be seen on a clear day.
The climate is very cold due to the altitude and the cone is covered by snow for several months of the year. The lowest recorded temperature is −38.0 °C while on June 2008 the highest temperature was recorded at 17.8 °C.

Mount Fuji is a modern postglacial stratovolcano is constructed above a group of overlapping volcanoes, remnants of which form irregularities on Fuji's profile. Growth of the younger Mount Fuji began with a period of voluminous lava flows from 11,000 to 8,000 years ago, accounting for four-fifths of the volume of the younger Mount Fuji.
Mount Fuji is located at the point where the Amurian Plate, the Okhotsk Plate, and the Philippine Sea Plate meet. Those plates form the western part of Japan, the eastern part of Japan, and the Izu Peninsula respectively." (Information provided by wikipedia.org)

Mount Pinatubo

"Mount Pinatubo is an active stratovolcano located on the island of Luzon, at the intersection of the borders of the Philippine provinces of Zambales, Tarlac, and Pampanga. It is located in the Cabusilan Mountain range separating the west coast of Luzon from the central plains, and is 42 km (26 mi) west of the dormant and more prominent Mount Arayat, occasionally mistaken for Pinatubo.
The volcano's ultra-Plinian eruption in June 1991 produced the second largest terrestrial eruption of the 20th century (after the 1912 eruption of Novarupta) and the largest eruption in living memory. The colossal 1991 eruption had a Volcanic Explosivity Index (VEI) of 6, and came some 450–500 years after the volcano's last known eruptive activity (estimated as VEI 5, the level of the 1980 eruption of Mount St. Helens), and some 1000 years after previous VEI 6 eruptive activity. Successful predictions of the onset of the climactic eruption led to the evacuation of tens of thousands of people from the surrounding areas, saving many lives, but surrounding areas were severely damaged by pyroclastic flows, ash deposits, and later by lahars caused by rainwater remobilizing earlier volcanic deposits: thousands of houses and other buildings were destroyed.
The effects of the eruption were felt worldwide. It ejected roughly 10 billion metric tonnes (10 cubic kilometres) of magma, and 20 million tons of SO2, bringing vast quantities of minerals and metals to the surface environment." (Information provided by wikipedia.org)

Mayon Volcano

"Mayon Volcano, also known as Mount Mayon, is an active stratovolcano in the province of Albay, in the Bicol Region, on the island of Luzon, in the Philippines.
Renowned as the "Perfect Cone" because of its almost perfectly conical shape, Mayon is situated 15 kilometres northwest of Legazpi City.
Mayon is an active stratovolcano. The current cone was formed through pyroclastic and lava flows from past eruptions. Mayon is the most active of the active volcanoes in the Philippines, having erupted over 48 times in the past 400 years." (Information was provided by wikipedia.org)

Krakatau Volcano Island

Krakatoa (Indonesian: Krakatau), also spelled Krakatau, is a volcanic island made of lava in the Sunda Strait between the islands of Java and Sumatra in Indonesia. The name is used for the island group, the main island (also called Rakata), and the volcano as a whole.

The best-known eruption of Krakatoa culminated in a series of massive explosions on August 26–27, 1883, which was among the most violent volcanic events in modern and recorded history. With a Volcanic Explosivity Index (VEI) of 6, the eruption was equivalent to 200 megatons (MT) of TNT—about 13,000 times the nuclear yield of the Little Boy bomb (13 to 16 kT) that devastated Hiroshim, Japan during World War II and four times the yield of the Tsar Bomba (50 MT), the largest nuclear device ever detonated.

Kelut Volcano

Kelud (Klut, Cloot, Kloet, Kloete or Kelut) is a volcano located in East Java on Java in Indonesia. Like many Indonesian volcanoes and others on the Pacific Ring of Fire, Kelud is known for large explosive eruptions throughout its history. More than 30 eruptions have occurred since 1000 A.D.
On May 19, 1919, an eruption at Kelud killed an estimated 5,000 people, mostly through hot mudflows (also known as "lahar"). More recent eruptions in 1951, 1966, and 1990 have altogether killed another 250 people. Following the 1966 eruption, the Ampera Tunnel was built on the southwestern side of the crater to drain the crater lake and thus reduce the lahar hazard. (Information provided by wikipedia.org)
