This week's USGS/Smithsonian GVP Volcano Update!
A volcano I had never heard of in the Kuril islands is showing signs of life: Kharimkotan. Satellite images show a thermal anomaly at the summit of the volcano - its last known eruption was in 1933.
Ash, sulfur dioxide and steam continue to erupt from Nyamuragira in the Congo, although lava flows have abated.
Crater C at Arenal had sporadic strombolian activity - which is par for the course for the Costa Rican volcano.
I must have missed this, but since December 14, the ash erupted at Gaua in Vanuatu has become denser and darker - and is still being emitted.
Increased fumarolic activity was spotted at Planchon-Peteroa in Chile, but this apparently common in the height of summer (in the southern hemisphere).
