Volcanic eruption map — live

Q: Which volcanoes are erupting right now?

Right now 93 volcanoes worldwide show a measurable activity signal — the strongest satellite thermal signal comes from Krasheninnikov (Russia) . Ash-cloud alerts are in force at, among others: ETNA, IBU, KRAKATAU, SEMERU, LEWOTOLOK. The list refreshes hourly from satellite heat detection and official alerts.

Q: How does the map know a volcano is active?

From three independent signals: NASA satellite thermal detections within 5 km of the crater, official USGS alert levels for US volcanoes, and aviation ash-cloud warnings (SIGMETs). The heat signal alone is not official eruption confirmation — the page labels it as such.

Q: How many volcanoes are there on Earth?

The map tracks 1,842 Holocene volcanoes (active within the past ~11,700 years) from Wikidata’s public-domain catalogue — of these, typically 40–100 show measurable activity at any one time.

Right now 93 volcanoes show a measurable activity signal worldwide — the strongest satellite thermal signal comes from Krasheninnikov (Russia) with 40 heat detections in 24 hours. 7 volcanic ash clouds are currently disrupting aviation.

The most active volcanoes right now

Our own satellite heat measurement: thermal detections from NASA fire-watching satellites within 5 km of the crater. Lava and eruption clouds emit heat — but a brushfire beside a volcano can signal too, which is why this is a heat signal — not an official eruption list.

What this page shows — and what it does not The heat signal is our own derived measurement from satellite thermal detections; a strong signal suggests an eruption but is not official confirmation — a brushfire on a volcano’s flank can look the same. The official status is declared by each country’s volcanological service; for US volcanoes we also show it (USGS). This page informs, it does not alert: in an emergency, follow your local authorities.

Frequently asked questions

Which volcanoes are erupting right now?
The list above shows the currently most active volcanoes — 93 volcanoes show a measurable signal right now, the strongest being Krasheninnikov (Russia). The data refreshes hourly.

How does the map know a volcano is active?
From three independent signals: satellite thermal detections around the crater (NASA FIRMS), official USGS alert levels, and aviation ash-cloud warnings (SIGMETs).

How many volcanoes are there on Earth?
Our catalogue lists 1842 Holocene volcanoes — of these, typically 40–100 show measurable activity at any one time.
