A new eruption at Kilauea volcano led the USGS to raise the Aviation Color Code to Red and the Volcano Alert Level to Warning on Monday, December 23, 2024. The eruption is occurring within a closed area of Hawai’i Volcanoes National Park.
Increased seismic activity has been recorded at Kilauea volcano over the past week, with an increase from 10 located events per day to 20 per day.
An underwater volcanic eruption is occurring at Ahyi Seamount, located about 18 km (11 miles) southeast of Farallon de Pajaros (Uracas) in the Northern Mariana Islands, part of the Mariana Volcanic Arc in the western Pacific Ocean.
A period of increased seismic activity started at Kamaʻehuakanaloa volcano (previously known as Lōʻihi) near Hawaii on November 1, 2024, with over 70 recorded earthquakes and two reaching M4.3. Seismicity remains above normal levels today, indicating magma movement beneath the volcano.
New temporary sensors were deployed by the USGS and PNSN around Mount Adams this month in response to the volcano experiencing an unusual spike in seismic activity since September 2024.
A gradual increase in volcanic unrest was observed at Spurr volcano in Alaska over the past couple of months, prompting the Alaska Volcano Observatory (AVO) to increase the Volcano Alert Level to Advisory and the Aviation Color Code to Yellow on October 16, 2024. Spurr is located about 120 km (75 miles) west of Anchorage.
Seismic activity at Mount Spurr volcano in Alaska remains elevated, with over 900 earthquakes detected so far in 2024, according to the Alaska Volcano Observatory (AVO). Despite the persistent unrest, no major shifts in earthquake frequency or intensity have been observed since the increase in seismic activity was first noted in April.
Earthquake activity has increased in Kīlauea’s middle East Rift Zone, near Makaopuhi rater at around 02:00 UTC, on Sunday, September 15, 2024. At the same time, ground deformation patterns west (uprift) of Puʻuʻōʻō suggest that another intrusive event could be occurring in this region.
A small, short-lived explosion was detected at the Atka volcanic complex in Alaska at 03:36 UTC on March 28, 2024 (19:36 AKDT on March 27).
A small explosion was detected at Kanaga Volcano, Alaska at 07:31 UTC on December 19, 2023.
