HVO Kilauea RED/WARNING - Episode 44 of the ongoing Halemaʻumaʻu eruption continues with lava fountains reaching 190 meters (625 feet) above the north vent.
Geographic Context
This volcano event occurred near Hilo (approximately 40 km away) in United States, an area that experiences a range of natural hazards.
Event Assessment
This event is Kilauea volcano showing alert level WARNING, being monitored by volcanological observatories for changes in eruptive behavior. Calamity.live has classified it as "critical" severity with a severity value of 90. The computed Calamity Score is 36 out of 100, suggesting contained impact at this time. The primary scoring components are: cascading (80), historical (80), intensity (30). Data for this event was sourced from usgs_volcano, one of the 250 scientific monitoring sources aggregated by Calamity.live.
Regional Monitoring Context
United States has a documented history of volcano events. Volcanic monitoring utilizes seismic networks, gas emission sensors, satellite thermal imaging, and ground deformation measurements. Volcanic activity can range from minor fumarolic emissions to large-scale eruptions, and continuous monitoring helps authorities issue timely warnings to at-risk populations.
Cascade Risk Analysis
This event may trigger secondary hazards through cascade effects. Cascade detection is an automated process that evaluates how primary disasters can trigger secondary events — for example, earthquakes triggering landslides, or volcanic eruptions causing lahars and pyroclastic flows. These secondary hazards can sometimes pose a greater threat than the initial event, particularly in mountainous terrain or densely populated areas.

Cascade Risks
Safety Information
During volcanic activity: follow evacuation orders from authorities. Volcanic ash can damage lungs — wear N95 masks or wet cloth over nose and mouth. Stay indoors during ashfall, close windows, and avoid driving. Lahars and pyroclastic flows can travel at high speeds — stay away from valleys and river channels near the volcano.
