Sinabung (Sumatra, Indonesia): The alert level of the volcano was again raised from "siaga" to "awas", the highest on the Indonesian 1-4 scale. The reason is a currently elevated risk of possibly larger pyroclastic flows, that could be triggered by collapse of the increasing volume of the viscous lava lobe emplaced on the upper SE flank.
The alert level of the volcano had been at 4 during late Nov 2013 until April 2014,- the first and so far most violent phase of pyroclastic flow generation after the lava had spilled over the summit crater and built a large lobe that reached the base of the cone.

Ambrym (Vanuatu): (3 Jun) The lava lakes on Ambrym remain very active.
As to visiting the island and the aftermath of Cyclone Pam, our partners on location (guides, porters etc) confirmed us that expeditions to Ambrym and Vanuatu in general can again run with no obstacles. Have a look at our volcano tour!

Cotopaxi (Ecuador): (3 Jun) The volcano has been showing signs of unrest. Since mid-April this year, and particularly during May, a marked increased in earthquakes and SO2 emissions have been detected, which could be signs of a magma intrusion beneath the volcano.
During May, about 3000 local earthquakes were recorded, a significant increased compared to April (628 quakes), and more than during the last seismic crisis in 2001-02.
