Krakatau volcano news & eruption updates:
Krakatau volcano (Indonesia) activity update and field report: increasing unrest

The volcano remains restless and produces intermittent explosions every few days or so from its new crater. These are likely caused by overheated water in the upper conduit flashing to steam, although no precise information is available.
When new magma will appear on the surface and start a more continuous eruptive phase is speculation, but a likely scenario for a not-too-distant future (months?). Thermal signals and seismic activity have been slowly picking up again during the past weeks, suggesting that magma might be rising from underneath.
During our recent (and still ongoing) tour to Krakatau
, expedition leader Galih took the following video illustrating the dramatic changes that the volcano underwent following the cone collapse in Dec last year. The island is now a barren ash desert, a low cone of crescent shape around the flat water-filled crater lake to the west.
Any new activity will start with phreatomagmatic (water-magma interaction) explosions.

17 days volcano trekking
: This is one of our most exciting volcano tours! Halmahera, North Sulawesi and the Sangihe Islands are not only very scenic and interesting as well as nearly unspoiled by tourism, but also home to some of the country's most active (and often erupting) volcanoes, inclduing Dukono, Ibu, Lokon, Soputan and Karangetang.
: The Azores, a cluster of volcanic islands in the Atlantic Ocean, are famous for their very pleasant climate, breathtaking green and unspoiled landscapes and nature. They also have deep history and you'll find warm hospitality. Our new tour, guided by a photographer and volcanologist, will lead to five islands: Sao Miguel, Faial, Terceira, Pico and Flores - each with its distinct character to discover.
