The magma chamber has been building pressure for 400 years. At 1,200°C and 28,000 tonnes per second, what comes next will not negotiate. This is not a crisis. This is geology.
Core magma temperature. Above critical threshold for explosive decompression.
Tonnes per second of lava output at current summit vent pressure readings.
Hypocentre depth of primary seismic swarm indicates rapid magma ascent.
Sulfur dioxide output at 14,000 tonnes per day — a 600% increase from baseline readings taken 72 hours ago. The gas is rising faster than the lava.
Active lava field now covering 340 hectares. Expansion rate: 12 hectares per hour at current output pressure. Wind direction unfavorable.
Ground deformation sensors detect 40cm uplift. Magma fills the upper storage system. Residents advised to monitor.
Dyke formation propagates laterally. Seismic swarm escalates. Evacuation zones A and B activated. Level 4 alert.
Fissure opening at the surface. Lava fountaining begins. Laze plume as flows reach the ocean. All zones evacuated.
Sustained effusion phase. Could last days or decades. The volcano is not finished until it is finished.
