Volcanic Alert LevelIn New Zealand, Volcano Alert Bulletins (VABs) are the official source of warnings and alerts including current Volcanic Alert Level (VAL),[1] intended to inform stakeholder agencies, authorities, and the public about emergencies so they can take action. The Ministry of Civil Defence & Emergency Management, through The National Emergency Management Agency is responsible for providing such alerts to warn about natural hazards.[2] A Scientific Alert Level is applied to the Volcano Status based on Indicative Phenomena. GNS Science operates the national geological hazards monitoring network (GeoNet).[3] LevelsThe Volcanic Alert Level system has six levels ranging from 5 (major volcanic eruption) to 0 (no volcanic activity):[4]
ElsewhereTo help prevent harm when living or working on or near a volcano, countries have adopted classifications to describe the various levels and stages of volcanic activity, the two main volcano warning systems being colour codes and/or numeric alert levels. [7]
The three common popular classifications of volcanoes can be subjective, and some volcanoes thought to have been extinct have erupted again. References
