Summary
Kīlauea in Hawaii produced the week’s largest eruption: episode 56 sent lava fountains up to about 200 m (660 ft) high on November 5, with a plume to about 5,500 m (18,000 ft). In Indonesia, Semeru sent pyroclastic flows (fast avalanches of hot gas and rock) about 5 km down its southeast flank on November 6. In the Philippines, Mayon stayed at Alert Level 3 after its October 30 eruption and emitted an ash plume 1,600 m high on November 3.

Semeru | Indonesia | Two eruptions with pyroclastic flows about 5 km southeast along Besuk Kobokan; ash 500–1,000 m above the summit | Nov 6 |

Active volcanoes this week
Twenty-five volcanoes are listed, grouped by region (Alaska, Europe and Iceland, Hawaii and the western Pacific, Indonesia, Japan, Latin America, the Philippines, Russia). Rows marked (pre-window) have no checked report from November 2–8; they are kept because their last stated alert was elevated. Most of those dates come from the Smithsonian/USGS weekly report for October 8–14, the newest issue available.
Volcano | Country | Alert level (scale, date) | Latest activity |
|---|---|---|---|
Great Sitkin | United States (Alaska) | Watch / Orange (USGS, 4 levels each; Nov 7) | Slow lava eruption continues inside the summit crater (Nov 7). |

New or changed alerts
Three changes were found, all from the US Geological Survey (USGS). No checked agency outside the United States changed a level during the week.
- Kīlauea (HVO/USGS), raised: aviation code Yellow to Orange (alert level Advisory to Watch) on November 2 after low-level lava began at the summit at 11:43 a.m. HST; notice issued 00:06 UTC November 3.
- Kīlauea (HVO/USGS), lowered: Orange to Yellow (Watch to Advisory) at 00:50 UTC November 7, after no eruptive activity followed the end of episode 56.
- Shishaldin (AVO/USGS), lowered: aviation code Yellow to Green at 22:29 UTC November 2, as unrest fell to near-background levels.
Just before the window, PHIVOLCS raised Mayon to Alert Level 3 on October 30 after a moderately explosive eruption; the previous level was not stated in the sources read.
About this report
This report summarises agency bulletins and news reports for November 2–8, 2026 (UTC); it is not an official warning, so follow local authorities for safety decisions. Alert scales differ by country: Indonesia uses levels 1–4, the Philippines 0–5, Japan 1–5, Mexico a three-colour “traffic light” with phases, and the United States a ground alert (Normal, Advisory, Watch, Warning) plus an aviation colour code (Green to Red), so the same number can mean different things. The Smithsonian/USGS weekly report available on November 9 covered only October 8–14, and Russia’s KVERT, Japan’s JMA and Guatemala’s INSIVUMEH could not be checked for this week, so several statuses are older than the week and are marked with their dates.
