Kavachi volcano is a shallow submarine volcano located south of the remote Vangunu Island in the Solomones. It is als known as Rejo te Kvachi, "Kavachi's Oven", and one of the most active of the Pacific with near surface eruptions every few years that often build temporary islands.
New islands were formed at least 9 times since its first recorded eruption during 1939. The new islands formed were not large enough and coated with solid lava flows to be able to resist wave erosion. They were submerged again after a few months after each eruption.
The frequent shallow submarine eruptions that sometimes breach the surface produce surtseyan activity, magma-water explosions that eject jets of steam, ash, and incandescent bombs above the sea surface. On some occasions during such eruptions, the vent was sealed sufficiently to produce liquid lava spattering and lava flows on the temporary islands. -> See whole entry

Kizimen volcano is an isolated, conical stratovolcano located in the Shchapina graben on the SE margin of the Central Kamchatkan Valley. After almost a century of quiet, it started to become restless in 2009 and erupt in late 2010. The new ongoing eruption has been building a new lava dome on the summit, and producing violent pyroclastic flows and ash plumes several kilometer high. The area around the volcano is unpopulated and the eruptions have therefore not caused damage. -> See whole entry
Klabat east of Manado city is an beautiful and isolated symmetrical stratovolcano rising almost 2000 m near the eastern tip of the northern arm of Sulawesi Island, forming the highest peak of Sulawesi. Klabat is probably still an active volcano and has active fumaroles on the summit, but there are no historic eruptions. A report of an eruption in 1683 probably was from nearby Tongkoko volcano (source: GVP).
Klabat is a popular destination for excursions by local students and climbers.

Kuchino-shima volcano is one of the active volcanic islands in the northern Ryukyu Islands in southern Japan. The small, 3x7 km wide island is located between the volcanic islands of Nakano-shima and Kuchinoerabu-jima and consists of 2 andesitic stratovolcanoes and a NW-SE-trending chain of lava domes.
There are 2 small villages on the northern end of the island, Nishinohama and Kuchino-shima.
Mae-dake is a lava dome that forms the highest point of the island. The last eruption of the volcano took place about 1200-1300 years ago and was dated by radiocarbon.
Kuchinoerabu-jima volcano is one of the active volcanoes of the Ryukyu Island arc, Japan. The 4x12 km wide island is sparsely populated and located 15 km west of Yaku-shima.
All historic activity which consisted in frequent explosions recorded since 1840 took place from Shin-take, but there is a young, but undated lava flow from the south flank of Furu-take that reached the coast.
The largest eruption in historic time occurred in December 1933 and caused damage in several villages located only a few km from the active crater. -> See whole entry
Kuju volcano is a group of active stratovolcanoes and lava domes in the northeastern corner of the large Aso caldera in central Kyushu, Japan.
Its historic eruptions recorded in the 17th and 18th century and as recently as 1995 were phreatic or hydrothermal explosions, caused by overheated ground water. The latest eruption where magma arrived at the surface was about 1600 years ago and formed Kuro-dake lava dome at the eastern end of the complex.
Kuju contains many hot springs and hydrothermal fields and there are 2 geothermal power plants. A particularly active hydrothermal area is Iwoyama on the NE flank of Hossho-zan lava dome, where a fumarole field was mined for sulfur during over 500 years.
Recent studies suggest that Kuju should be considered one of the more hazardous volcanoes in Japan because of its history of producing pyroclastic flows from lava dome collapse. -> See whole entry
