A major eruption took place at Lewotobi Laki-laki volcano, Indonesia on Sunday, November 3, 2024, producing an ash column up to 12.2 km (40 000 feet) above sea level. The Aviation Color Code was raised to Red.
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.
The Kanlaon Volcano on Negros Island, Philippines, produced three minor ash plumes from its summit crater on November 2, 2024, during brief eruptions lasting between four and twelve minutes each. The plumes rose to approximately 400 m (1 310 feet) above the crater and drifted southwest. No seismic or infrasonic signals accompanied the events, indicating low-energy emissions.
Te Wai ā-moe, the Crater Lake of Ruapehu volcano in New Zealand, is experiencing a mild heating trend, with temperatures rising from 8 °C (46.4 °F) to approximately 10 – 11 °C (50 – 51.8 °F). The recent changes have been noted in late October 2024, following several months of cooling that began in February of the same year.
A significant lava overflow occurred at Erta Ale’s summit vent on October 29, 2024, resulting in the formation of a temporary lava lake and high-spattering plumes.
With the end of October, uplift and magma accumulation continued steadily in Iceland’s Svartsengi volcanic region, increasing the likelihood of an intrusion or possible eruption toward late November. Seismic activity near the Sundhnúkar crater remains low, with only minor daily tremors recorded.
Intense explosions at the Lewotobi Laki-laki volcano in Flores, Indonesia, on October 31, 2024, have generated ash plumes up to 2.5 km (1.5 miles) above sea level, impacting nearby communities. This series of eruptions began in late October 2024, with regular blasts occurring 3 to 4 times daily. The activity has continued since June 13, when the Alert Level was raised to Level 3 (Siaga).
New activity/unrest was reported for 5 volcanos from October 23 to 29, 2024. During the same period, ongoing activity was reported for 17 volcanoes.
The Santiaguito volcanic dome complex in southwestern Guatemala is experiencing increased eruptive activity, with frequent explosions and lava block detachment from the Caliente Dome. The eruptions produce ash plumes reaching 3.5 km (11 500 feet) a.s.l. and dispersing it up to 30 km (19 miles) southwest and south.
Mount Marapi experienced four explosions on October 27, 2024, producing thick ash columns up to 4 km (13 000 feet) a.s.l. that drifted westward over populated areas, blanketing them in ash.
