Earthquakes near erupting volcanoes this week

Quakes under a volcano can track magma moving, but they are common at active volcanoes and are not a forecast by themselves. These are the M2.5+ quakes USGS listed within 30 km of a volcano on this page in the past 7 days:

The longest-running eruptions

Many "eruptions today" have been going on for decades. The longest in the Smithsonian list are Santa Maria in Guatemala (since 1922), Dukono in Indonesia (since 1933), Stromboli in Italy (since 1934), Erebus in Antarctica (since 1972), Sheveluch in Russia (since 1999). Most of them produce small explosions, gas and lava, not large blasts.

What VEI means

The Volcanic Explosivity Index (VEI) runs from 0 to 8. Each step up means roughly ten times more erupted material. VEI 0-1 are gentle lava eruptions like Kilauea's; VEI 2-3 are explosive eruptions that disrupt flights nearby; VEI 6 was Pinatubo in 1991. The VEI here is the largest so far in each continuing eruption, as assessed by the Smithsonian.

Ash and air travel

Volcanic ash can stop jet engines, so nine Volcanic Ash Advisory Centers (VAACs) around the world track ash clouds and advise airlines. If your flight passes near an erupting volcano, check your airline's notices; airports near large eruptions can close for hours or days.

Staying safe near a volcano

Follow your local civil protection or volcano observatory: they set exclusion zones and evacuation orders. Stay out of closed areas, keep away from river valleys that can carry mudflows (lahars), and wear a well-fitting mask during ashfall. Never rely on this page for safety decisions.

Questions and answers

Is a volcano erupting right now?
Yes: on any given day several dozen volcanoes are erupting. The Smithsonian Global Volcanism Program lists 38 continuing eruptions, many of them long-running and small, such as Santa Maria (since 1922), Dukono (since 1933), Stromboli (since 1934). New eruptions can take days or weeks to enter that list; national observatories report them first.
Is Kilauea erupting?
USGS lists Kilauea at ADVISORY / YELLOW (2026-10-28). The latest USGS summary: "The Halema'uma'u eruption of Kīlauea remains paused following episode 55 on October 17. The forecast for episode 56 fountaining has been pushed to Nov. 1-7, 2026.". Check the Hawaiian Volcano Observatory for the current status.
Is Yellowstone going to erupt?
There is no sign of that. USGS lists Yellowstone at NORMAL / GREEN. The Yellowstone Volcano Observatory says the chance of a large eruption in any given year is extremely small, and that hydrothermal explosions and earthquakes are the more likely hazards. No one can predict an eruption date.
What do the US volcano alert levels mean?
NORMAL means background activity. ADVISORY means elevated unrest above background. WATCH means heightened unrest with more chance of eruption, or a minor eruption under way. WARNING means a hazardous eruption is under way or expected soon. The aviation colour code (GREEN, YELLOW, ORANGE, RED) gives the same steps for ash and flights.
What was the biggest volcanic eruption?
In recorded history, Tambora in Indonesia in 1815 (VEI 7) was the largest; it caused the "year without a summer" in 1816. The largest of the past century was Pinatubo in the Philippines in 1991 (VEI 6). The January 2022 Hunga Tonga-Hunga Ha'apai eruption sent the highest volcanic plume ever measured, about 57 km high.
