This week’s USGS/Smithsonian GVP Volcano Update!
Highlights include:
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).
