Ecuadorian Tungurahua volcano, one of South America's most prominent volcanoes, is showing early warning signs of potential flank collapse, a new research paper published in Science Direct suggests. A previous eruption of Tungurahua, around 3 000 years ago,…
A series of small explosions and tremor bursts have been detected in seismic data at Semisopochnoi over the past 7 hours and are continuing, representing a significant uptick in activity, the Alaska Volcano Observatory (AVO) reported at 09:19 UTC on February 15,…
New activity/unrest was reported for 5 volcanoes from February 5 to 11, 2020. During the same period, ongoing activity was reported for 10 volcanoes. New activity/unrest: Kuchinoerabujima, Ryukyu Islands (Japan) | Piton de la Fournaise, Reunion Island (France) |…
Satellite imagery taken by the Copernicus Sentinel-2 satellite on February 3, 2020, showed a moderate thermal signature at Tanzania's Ol Doinyo Lengai volcano, indicating that natrocarbonatite lava erupted a few days ago. This is the only volcano in the world…
Lahars were recorded at Peru's Ubinas and Huaynaputina volcanoes on February 11, 2020. Geophysical Institute of Peru (IGP) is urging residents and tourists to stay away. IGP said the seismic station at Ubinas recorded internal tremors associated with the lahar…
Earthquake activity near Mt. Thorbjorn, Grindavik has decreased over the past 6 days, but small earthquakes are still being detected. Indications are that the crustal deformation pattern has changed, however, the uplift has slowed down. In total, the uplift is about…
Mahoran authorities have started planning emergency and safety measures in case of dangerous seismic or volcanic activity near Mayotte due to a newly-discovered underwater volcano, which has been showing continuous activity since 2018. The seismic swarm found about…
A new eruption has started at Reunion's Piton de la Fournaise volcano at 06:40 UTC on February 10, 2020. The last eruption of this volcano took place in October 2019. First signs of awakening were detected at 06:27 UTC today with the start of the strong seismic…
New activity/unrest was reported for 3 volcanoes from January 29 to February 4, 2020. During the same period, ongoing activity was reported for 17 volcanoes. New activity/unrest: Kuchinoerabujima, Ryukyu Islands (Japan) | Rincon de la Vieja, Costa Rica | Taal, Luzon…
An earthquake swarm is in progress at the Michoacan-Guanajuato volcanic field, Mexico. At this time, it's unclear whether the quakes are volcanic or tectonic in origin. The zone contains over 1 400 vents and covers an area of approximately 200 x 250 km (125 x…
