Increased seismicity was detected under Grímsvötn volcano in SW Iceland on August 2, 2022, forcing the Icelandic Meteorological Office (IMO) to raise the Aviation Color Code for the volcano to Yellow. This is now the third volcano in Iceland with Yellow Aviation Color Code in effect – after Askja and Krysuvik. The last eruption of this volcano took place in 2011.
Volcanic activity at Anak Krakatau increased on August 2, 2022, with the first of several eruptions starting at 08:49 UTC. It had maximum amplitude of 33 mm and lasted 32 seconds, ejecting ash up to 1.5 km (4 900 feet) above the peak. The Aviation Color Code remains at Orange.
More than 5 500 earthquakes have been registered east and west of Fagradalsfjall volcano, Reykjanes Peninsula, Iceland since around 09:00 UTC on July 30, 2022. The Aviation Color Code remains at Yellow.
A powerful earthquake swarm started at Krísuvík volcano, just northeast of Fagradalsfjall and a short distance north of Fagradalshraun lava field, on July 30, 2022, at a depth of about 5 to 7 km (3 – 4 miles). As a result, the Icelandic Meteorological Office (IMO) raised the Aviation Color Code for the volcano to Yellow. The last eruption at this volcano took place in 2021.
The Alert Level for Raung volcano was raised from 1 to 2 on July 29, 2022. The decision was based on the results of seismic monitoring and unstable conditions at the crater. The last eruption of this volcano took place in 2021 (VEI 2).
New activity/unrest was reported for 2 volcanoes from July 20 to 26, 2022. During the same period, ongoing activity was reported for 15 volcanoes.
GeoNet is reporting an increase in earthquake activity under Lake Taupō since May 2022. Lake Taupō is a large caldera volcano, a special type of volcano that has rare but unusually large eruptions.
Scientists from the Institute of Geosciences, the Icelandic Met Office (IMO) and representatives of Iceland’s civil protection met on July 25, 2022, to discuss land changes and earthquakes at Askja volcano observed over the past few months.
Monitoring networks at Stromboli volcano recorded lava overflow from the volcano’s North crater area starting at 17:30 UTC on July 27, 2022.
A new increase in seismic activity has been recorded in the area of the Chiles-Cerro Negro Volcanic Complex (CVCCN) and its surroundings since May 2022, which includes volcano-tectonic and long-period earthquakes which are now at more shallow depths than those recorded in previous years.
