Jebel al-Tair ("bird mountain") volcano is the northernmost active volcano rising above sea level on the rift axis of the south-central part of the Red Sea.
Its western spelling varies from Jebel at Tair to Jebel al Tair, Djebel Teyr, Jabal al Tayr,, Jibbel Tir and other variants.
Jebel al Tair's activity is mainly effusive, but explosive eruptions or explosive phases at the beginning of effusive eruptions occur as well and have produced ash and pumice layers. The first historically recorded eruptions were explosive eruptions (which are easier to detect) in the 18th century. Jebel al Tair's last eruption was in 2007-2008 and killed 8 soldiers and destroyed a military base on the island. -> Voir la description complète

Jolo volcano is a group of young cinder cones and explosion craters on the 60-km-wide Jolo Island located off the Zamboanga Peninsula on SW Mindanao Island in the southern Philippines 190 km NE of Sabah, Malaysia.
It is part of the Sulu arc and contains several young volcanic vents, including Mt.

This activity most likely took place al Lake Seit, where a still active solfatara is found.
Hot springs also occur at the craters on Cagayan Sulu.
A reported eruption in 1641 most likely was the eruption of Parker volcano on Mindanao instead. -> Voir la description complète

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. -> Voir la description complète
