Right now, four volcanoes are breathing harder than usual. Ambrym in Vanuatu. Mayon in the Philippines. Masaya in Nicaragua. Sabancaya in Peru. Each one is sending signals—some visible only to satellites, others detectable only by seismometers buried in ash and rock. The question isn't whether they're active. It's: how close are they to dangerous release?

That's exactly what Pandita Data's Brain Dashboard calculates every 15 minutes. Not guesswork. Not folklore. Pure signal fusion—a real-time algorithm that weights four independent volcanic hazard indicators and returns a single AI risk score you can trust.

THE VOLCANIC HAZARD FORMULA

Volcanic risk on the Brain Dashboard doesn't rely on one sensor or one expert opinion. Instead, it combines four scientifically independent signals, each weighted by its predictive power:

🛰
NASA EONET Active Events
Thermal infrared detection of hot lava, new vents, or gas plumes directly from Earth Observing Network satellites.
40% Weight
📊
Seismicity Near Volcanoes
Real-time earthquake counts and magnitudes within 20 km of summit. More quakes = magma migration and pressure building.
30% Weight
💨
SO₂ Emissions + Thermal Anomaly
Sulfur dioxide plumes (from Copernicus satellites) and subsurface heat signatures. Signals of active degassing.
20% + 10% Weight

WHY SO₂ IS THE KEY VOLCANIC SIGNAL

Volcanic gases, especially sulfur dioxide, are a hidden language that magma speaks before it erupts. SO₂ in the atmosphere means magma is rising, releasing dissolved volatiles. It's not an opinion—it's chemistry.

The Brain Dashboard ingests daily SO₂ column density data from Copernicus Sentinel-5P and correlates it with historical eruption sequences. High SO₂ flux 72 hours before a lava fountaining? That correlation is locked into the algorithm.

THE SEISMIC-VOLCANIC CONNECTION

REAL-TIME INTEGRATION

Seismicity is the heartbeat. When USGS reports a swarm—say, 47 micro-earthquakes in 6 hours near Mayon—the Brain Dashboard immediately reweights the 30% seismic component upward. It's not a delay. It's instantaneous. The risk score changes as the data arrives.

Check the live scores, city-by-city volcanic assessments, and 3D eruption plume simulations on the Brain Dashboard. For neighborhood-level volcanic risk in major cities near active volcanoes, visit the Disaster Report.

Volcanoes don't give warnings in words. They give them in numbers. The Brain Dashboard translates those numbers into risk scores you can act on.
