What four signals determine Brain Dashboard's volcanic hazard score?

The four signals are: NASA EONET Active Volcanic Events (40%) — confirmed eruptions from global volcano monitoring networks; Seismicity Near Volcanoes (30%) — M2.5+ swarms within 50km of known volcanic centers; SO2 Emissions (20%) — measured by Sentinel-5P TROPOMI spectrometer; Thermal Anomaly (10%) — elevated surface temperature from MODIS/VIIRS.

Why is SO2 a key volcanic precursor?

SO2 (sulfur dioxide) is released from magma as it degasses during ascent. Increasing SO2 flux — measured by satellite spectrometry — indicates fresh magma moving toward the surface. Monitoring SO2 from orbit allows early detection of volcanic unrest weeks before eruption, providing the critical warning window that ground networks alone cannot guarantee.

Imagine a volcano awakening in the dead of night. Ground tremors spike. Sulfur dioxide plumes pierce the stratosphere. Thermal sensors detect a new hot spot. But how do you quantify that danger in real time? The Brain Dashboard's volcanic hazard engine doesn't guess—it synthesizes four precision signals into a single, live risk score that updates as the volcano breathes.

THE VOLCANIC HAZARD FORMULA

Volcanic risk is not one number. It's a weighted blend of four independent data streams, each capturing a different facet of volcanic behavior. Visit panditadata.com/brain_dashboard to watch these signals update live across 4 active volcanoes today: Telica (Nicaragua), Ivao Group (Russia), Titan Ridge (Papua New Guinea), and Kikai (Japan).

NASA EONET Active Events (40%)

Direct satellite observations of eruptive activity, ash plumes, and lava flow extent. EONET feeds confirmed thermal and visual anomalies in real time.

Primary Signal

📡

Seismic Activity Near Volcano (30%)

Magnitude, frequency, and depth of earthquakes within a 10 km radius. Shallow swarms signal magma migration; deep tremors indicate hydrothermal stress.

Pressure Indicator

💨

SO2 Emissions (20%) + Thermal (10%)

Sulfur dioxide columns measured by TROPOMI satellite; coupled with infrared thermal anomalies at summit craters. Early warning of subsurface gas release.

Chemical Signature

WHY SO2 IS THE KEY VOLCANIC SIGNAL

Sulfur dioxide doesn't lie. When magma rises, dissolved gases are released long before lava reaches the surface. SO2 plumes detected at 20+ km altitude are a bellwether of imminent eruption. Combined with thermal anomaly spikes (surface temperature > 400 K), SO2 becomes the most reliable early alarm for explosive activity.

LIVE MONITORING

The Brain Dashboard recalculates volcanic scores every 6 hours as new satellite passes and seismic networks feed data. Cities within 100 km of an active volcano can trigger emergency alerts when combined risk exceeds 7.0 on a 10-point scale. Check your region's exposure on panditadata.com/disaster_report for city-level volcanic threat profiles.

THE SEISMIC-VOLCANIC CONNECTION

Earthquakes alone don't define volcanic risk—but they're its shadow. A magnitude 4.5 swarm 2 km below the summit of Kikai suggests magma chamber pressurization. The same swarm 50 km deep means regional stress, not imminent eruption. The Brain Dashboard's geospatial filter isolates shallow seismicity as a 30% multiplier, creating a dynamic risk landscape that shifts as the volcano evolves.

Real-time volcanic hazard assessment is now transparent and accessible. Four signals. One score. Continuous update. That's how we measure the earth's fury before it strikes.
