Volcano Activity Tracker: is it worth driving out tonight

Iceland's Reykjanes peninsula entered a new volcanic period in 2021 after ~800 years of dormancy. There have been 9 eruptions since: Fagradalsfjall (2021, 2022), Litli-Hrútur (2023), Sundhnúkur crater row (Dec 2023, Jan 2024, Feb 2024, Mar 2024, May 2024, Nov 2024, plus 2026 dates as of writing). Each one drew huge crowds, and the pattern is now familiar: warning signs → evacuation → eruption starts → roads reopen within days → viewing site established → weeks to months of activity → quiescence.

The dangerous mistake: going to the eruption site when an eruption is just starting (gas hazards, unstable ground) or going past the official viewing perimeter (lava field collapse, hidden cracks). The roads to the active sites often change month to month — never rely on an old blog post for the route.

This tool summarises the latest status (as of 2026-10-06) and gives you a specific plan.

The alert tells you whether there's active eruption. The sites panel lists currently visible sites with safe viewing perimeters. The livestream box tells you whether watching from a livestream is the better option (yes, usually — eruptions are mostly visible from a webcam in daylight; at night the lava glow is more dramatic than anything you'll see in person because of the long-exposure problem).

Volcanoes change hands and walk faster than this tool updates. Status as of late 2026 may differ from your visit. Always verify current status via the Icelandic Civil Protection (almannavarnadeild) and Safe Travel Iceland (safetravel.is). The viewing perimeter is set by the local police chief — do not cross it.

Gas hazards (SO₂) can shift with wind direction. The official perimeter accounts for typical conditions; if the wind shifts, gas can concentrate downwind of the eruption. Move upwind if you smell sulfur.
