As a nation we have a history of pushing through emergency legislation in the wake of natural hazard events to govern our emergency response. This has led to an expectation that post-event bespoke frameworks will be introduced to manage post-disaster recovery. Is there a better way? I…
Listen to the podcastHow Pacific countries are learning more about early warning systems from the Tongan volcanic eruption and tsunami in 2022.Also, the importance of maintaining messages for natural disasters in the Pacific and how to make sure they break through.And how Timor Leste journalists feel the pressure when it comes to reporting on disasters…
[...]One of our planet's large undersea volcanoes, the Hunga Volcano in the South Pacific, astonished scientists when it erupted in January 2022. The blast sent pressure waves around the planet. It blew a whopping 58,000 swimming pools worth of water into the atmosphere — an unprecedented amount. And the explosion's plume of ash and water reached over 3…
Small Island Developing States (SIDS) are incredibly vulnerable to intensifying hazards from climate change. But the challenges that SIDS face in adapting can only be understood by looking at how these impacts interact with other risks – not all of them environmental.
A dire example of this is the recent eruption of the Hunga Tonga-Hunga Ha’a…
New research reveals more about the magnitude of January eruption, as researchers call for better preparedness
The eruption of the Hunga Tonga-Hunga Ha’apai volcano in January created an initial wave 90 metres high – almost the height of the Statue of Liberty (93m)
University of Bath tsunami expert calls for better warning systems to detect volcanic…
Does sea level rise increase the frequency of earthquakes and volcanic eruptions? Or does the melting of glaciers due to temperature rise lead to more volcanic eruptions?
Scientists have long offered this hypothesis, and now they have a chance to test this theory.
“Recent studies have proposed a causal link between rising sea-level during periods of w…

Tongan officials said the Pacific nation’s practice of running tsunami drills had also played a part in saving lives, even as the island archipelago sustained extensive damage to property, with the majority of houses on some islands being completely destroyed. The confirmed death toll from Saturday’s explosion and tsunami, which was felt as far a…
Tsunamis are surface water gravity waves originating from the sudden displacement of water occurring in an earthquake, volcanic crater collapse, or underwater landslide. The local propagation speed of tsunamis is given by the square root of g.H, where g is the acceleration of gravity and H is the local water depth. As the water depth of the oceans is we…

GNS Science is a Crown Research Institute (CRI) owned by the New Zealand Government and is New Zealand’s largest geological science organisation. It provides geological, geophysical and isotopic research and consultancy services to government and industries within New Zealand and internationally.
Within GNS Science, the Natural Hazards Divis…
Convincing individuals to embark on activities that would reduce their vulnerability to natural hazards is difficult, especially in communities that have not recently experienced the impact of natural hazards. This research investigated risk knowledge and interpretation in the South African community in Auckland.
The research confirmed the subjectivity…
The scientific program of IUGG 2011 includes symposia, poster presentations and workshops on a wide range of themes related to geophysics and geodesy, including:
- Hydrological Sciences
- Meteorology and Atmospheric Science
- Physical Sciences of the Oceans
- Seismology and Physics of the Earth’s Interior
- Volcanology and Chemistry of the Earth's Inte…
This map estimates the risk areas for a number of volcanic hazards, including flying rocks and gases from eruptive vents, lahar and dangerous flows, ash and rain, for the island of Ambae in Vanuatu. It also provides a list of recommended actions for each risk in the event of an eruption.
For primary school children, featuring Stan the dog and five children - Dan, Ana, Frankie, Matt and Beth - who model what to do in an emergency, around the 4 "Rs" of emergency management (reduction, readiness, response, recovery). This resource has three components, each of which can be used independently or in conjunction with each other: a guide for t…

What's the risk of a major earthquake, volcanic eruption, tsunami or wildfire in New Zealand – and how might it play out?
The next big one
A major Alpine Fault earthquake is likely within our lifetime.
There are only a few places in the world where you can see a major plate boundary naturally exposed above ground. One is at Gaunt Cree…
This report presents the institutional and legal framework for disaster risk reduction in Pacific island countries, and describes their common disaster risks and natural hazards, such as flood, drought, landslide, earthquake, cyclone, volcano and tsunami. It outlines the strategies, plans, projects and activities related to disaster prevention and risk…
