Volcanic Alert Level
In New Zealand, Volcano Alert Bulletins (VABs) are the official source of warnings and alerts including current Volcanic Alert Level (VAL), 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. A Scientific Alert Level is applied to the Volcano Status based on Indicative Phenomena. GNS Science operates the national geological hazards monitoring network (GeoNet).GeoNetWhakaari/White Island - Updates/ref> Levels The Volcanic Alert Level system has six levels ranging from 5 (major volcanic eruption) to 0 (no volcanic activity): Elsewhere To 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 colo ...

Volcano Alert Bulletins
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes can also form where there is stretching and thinning of the crust's plates, such as in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande rift in North America. Volcanism away from plate boundaries has been postulated to arise from upwelling diapirs from the core–mantle boundary, deep in the Earth. This results in hotspot volcanism, of which the Hawaiian hotspot is an example. Volcanoes are usually not created where two tectonic plates sli ...

Ministry Of Civil Defence & Emergency Management (New Zealand)
The National Emergency Management Agency (NEMA; Māori: ''Te Rākau Whakamarumaru'') is the public service department of New Zealand responsible for providing leadership and support around national, local and regional emergencies. It is an autonomous departmental agency hosted by the Department of Prime Minister and Cabinet. It replaced the Ministry of Civil Defence and Emergency Management in December 2019. The Minister for Emergency Management is currently Kieran McAnulty. History No formal civil defence or emergency management structure existed in New Zealand until the 1930s, when the increasing threat of war prompted the formation of the Emergency Precautions Scheme, which was controlled by the Department of Internal Affairs. In addition to war, earthquake risk was another concern of the Scheme, prompted in part by the 1931 Hawke's Bay earthquake. During World War II, the name of the EPS was changed to Civil Defence. While EPS/Civil Defence did not need to respond to any in ...

GNS Science
GNS Science ( mi, Te Pū Ao), officially registered as the Institute of Geological and Nuclear Sciences Limited, is a New Zealand Crown Research Institute. It focuses on geology, geophysics (including seismology and volcanology), and nuclear science (particularly ion-beam technologies, isotope science and carbon dating). GNS Science was known as the Institute of Geological and Nuclear Sciences (IGNS) from 1992 to 2005. Originally part of the New Zealand Government's Department of Scientific and Industrial Research (DSIR), it was established as an independent organisation when the Crown Research Institutes were set up in 1992.
Crown Research Institutes Act 1992.
As well as undertaking basic research, and operating the national geological hazards monitoring network (GeoNet)

2019 Whakaari / White Island Eruption
On 9 December 2019 Whakaari / White Island, an active stratovolcano island in New Zealand's northeastern Bay of Plenty region explosive eruption, explosively erupted. The island was a popular tourist destination, known for its volcanic activity, and 47 people were on the island at the time. Twenty-two people died, either in the explosion or from injuries sustained, including two whose bodies were never found and were later declared dead. A further 25 people suffered injuries, with the majority needing intensive care for severe burns. The ongoing seismic and volcanic activity in the area as well as heavy rainfall, low visibility and toxic gases hampered recovery efforts over the week following the incident. Experts identified the event as a phreatic eruption: a release of steam and volcanic gases that caused an explosion, launching volcanic rock, rock and volcanic ash, ash into the air. Following the eruption, investigations resulted in WorkSafe New Zealand charging multiple tour ...

Volcano Warning Schemes Of The United States
In October 2006, the United States Geological Survey (USGS) adopted a nationwide alert system for characterizing the level of unrest and eruptive activity at volcanoes. The system is now used by the Alaska Volcano Observatory, the California Volcano Observatory (California and Nevada), the Cascades Volcano Observatory (Washington, Oregon and Idaho), the Hawaiian Volcano Observatory and the Yellowstone Volcano Observatory (Montana, Wyoming, Colorado, Utah, New Mexico and Arizona). Under this system, the USGS ranks the level of activity at a U.S. volcano using the terms "normal", for typical volcanic activity in a non-eruptive phase; "advisory", for elevated unrest; "watch", for escalating unrest or an eruption underway that poses limited hazards; and, "warning", if a highly hazardous eruption is underway or imminent. These levels reflect conditions at a volcano and the expected or ongoing hazardous volcanic phenomena. When an alert level is assigned by an observatory, accompanying tex ...

Mount Yasur
Mount Yasur is a volcano on Tanna Island, Vanuatu, high above sea level, on the coast near Sulphur Bay, northeast of the taller Mount Tukosmera, which was active in the Pleistocene. It has a largely unvegetated pyroclastic cone with a nearly circular summit crater 400 m in diameter. It is a stratovolcano, caused by the eastward-moving Indo-Australian Plate being subducted under the westward-moving Pacific Plate. It has been erupting nearly continuously for several hundred years, although it can usually be approached safely. Its eruptions, which often occur several times an hour, are classified as Strombolian or Vulcanian. A large lava plain creeps across the valley at the base. The glow of the volcano was apparently what attracted Captain James Cook on the first European journey to the island in 1774. Today, the mountain is a sacred area for the John Frum cargo cult. Members of the cult revere John Frum, a deified messenger who foretold the bringing of wealth to the isl ...

Emergency Management In New Zealand
An emergency is an urgent, unexpected, and usually dangerous situation that poses an immediate risk to health, life, property, or environment and requires immediate action. Most emergencies require urgent intervention to prevent a worsening of the situation, although in some situations, mitigation may not be possible and agencies may only be able to offer palliative care for the aftermath. While some emergencies are self-evident (such as a natural disaster that threatens many lives), many smaller incidents require that an observer (or affected party) decide whether it qualifies as an emergency. The precise definition of an emergency, the agencies involved and the procedures used, vary by jurisdiction, and this is usually set by the government, whose agencies (emergency services) are responsible for emergency planning and management. Defining an emergency An incident, to be an emergency, conforms to one or more of the following, if it: * Poses an immediate threat to life, hea ...
