Eruption Warnings Days Ahead
Observatories issue warnings with a stated probability and expected size days to weeks before an eruption at monitored volcanoes.
Open in the interactive tree →It would need precursors that transfer between volcanoes, better coverage of the many unmonitored ones, and models that say how large an eruption will be. Even a probabilistic days-ahead alert with known false-alarm rates would change how cities and airlines react.
What it brings
- Planned evacuations instead of last-minute ones
- Flight rerouting and port closures timed in advance
- Fewer false alarms and less needless disruption
- Targeted preparation for large explosive eruptions
