Eruption resumes at Kilauea volcano, Aviation Color Code raised to Red, Hawaii
The eruption at Kīlauea volcano in Hawaii resumed at approximately 02:34 UTC on January 6, 2023, after nearly a month of pause.
Sentinel-2 satellite views erupting Mauna Loa volcano, Hawai’i
Mauna Loa started erupting at around 09:30 UTC on November 28, 2022 (23:30 LT on November 27) in Moku‘āweoweo, the summit caldera of Mauna Loa, inside Hawai‘i Volcanoes National Park. Mauna Loa is the largest active volcano on our planet. Its last eruption took place in 1984 (VEI 0).
Earthquake swarm under Takawangha volcano, Aviation Color Code raised to Yellow, Alaska
Seismic activity under Takawangha volcano, Alaska increased over the past couple of days and intensified on November 18, 2022, forcing the Alaska Volcano Observatory (AVO) to raise the Aviation Color Code to Yellow and the Volcano Alert Level to Advisory.
Reactivation of dormant Edgecumbe volcano, Alaska
Researchers reporting in AGU’s Geophysical Research Letters show that the seismic swarm detected near Mt. Edgecumbe volcano in Southeast Alaska, U.S. in April 2022 was caused by magmatic activity taking place under this transform fault volcano previously considered dormant.
Slow eruption of lava at Pavlof volcano, Alaska
Pavlof Volcano continues to erupt from the active vent on its east flank, just below the summit. The Aviation Color Code remains at Orange. Previous eruptions of Pavlof indicate that the level of unrest can change quickly and the progression to more significant eruptive activity can occur with little or no warning.
Earthquake swarm beneath Kamaʻehuakanaloa (Lōʻihi) seamount likely the result of magma movement, Hawai’i
The Hawaiian Volcano Observatory (HVO) has detected increased seismic activity beneath Kamaʻehuakanaloa (formerly known as Lōʻihi) seamount, south of the Island of Hawaiʻi over the past few days. The activity is likely the result of magma movement beneath Kamaʻehuakanaloa seamount and currently shows no sign of leading to an eruption. The last eruption at this volcano took place in 1996 (VEI 0).
Cleveland volcano – Aviation Color Code and Volcano Alert Level raised to Yellow/Advisory, U.S.
Elevated surface temperatures and sulfur dioxide emissions have been detected at Cleveland volcano, Alaska, U.S. over the past couple of days, representing a departure from background activity.
Earthquake swarm detected in the vicinity of Edgecumbe volcano, U.S.
m of earthquakes has been detected in the vicinity of Mount Edgecumbe volcano, beginning at about 10:00 UTC on April 11, 2022. The cause of the swarm is currently unknown. A small number of earthquakes were also recorded in 2020 but this swarm is unusual in the number of events. The last eruption of this volcano was in 2220 BCE (± 100 years).
Increased rate of uplift near South Sister volcano, Oregon
Cascades Volcano Observatory geophysicists have detected a subtle increase in the rate of uplift of the ground surface about 5 km (3 miles) west of South Sister volcano, Oregon, U.S. Episodes of increased uplift have been observed in this area before, and the…
Lava flow field at Great Sitkin grows to more than 1.3 square km, Alaska
Seismicity at Great Sitkin volcano continues at low but above background levels and satellite data shows elevated surface temperatures. In addition, new SAR images from DLR show the lava flow field has grown to more than 1.3 km2 (0.5 mi2). The SE edge seems to have…
