A team of researchers from the University of Manchester, Wairakei Research Center and National Isotope Center, GNS Science, has found that it is possible to use satellite data to detect the early stages of a volcanic eruption. In their paper published in the journal Science Advances, the group describes their study of satellite data that c…
This publication presents the Volcanic Ash Probabilistic Assessment tool for Hazard and Risk (VAPAHR), the methodology that supported it and the application of the tool to the Asia-Pacific region for the 2015 Global Assessment Report on Disaster Risk Reduction.
Recommendations for future research include:
the incorporation of updated eruption data w…
This report contains a synopsis of volcanism from a hazard and risk perspective and highlights the wide range of hazards posed by volcanoes and describes their diverse impacts on communities. This technical report complements a shorter summary background paper focussed on the GAR15 agenda and designed for a wider non-technical readership.…
The Cascade Volcanic Arc stretches from Northern California to southern British Columbia and contains more than a dozen volcanoes.The U.S. Geological Survey classifies 11 of them, including Mount Baker and Mount Hood, as “very high threat,” meaning they pose significant hazards to people and infrastructure. Despite the potential for danger, scientists h…
The eruption of the Hunga Tonga-Hunga Ha’apai volcano in January 2022 was a stark reminder of how telecommunications preparedness can mean the difference between silence and life-saving response.
On the tiny and remote island of Vava’u in Tonga, a satellite phone crackles to life. An island resident presses the phone to his ear, uttering a cry of relie…
On 15 January 2022, the Hunga-Tonga-Hunga-Ha’apai volcano eruption was felt across the Pacific Ocean and beyond, releasing energy equivalent to hundreds of Hiroshima nuclear explosions and creating supersonic air pressure waves that were observed from space.
Connectivity is key when talking about disaster response. In a world highly interconnected by…
Tonga’s underwater eruption hints at need for more seismic stations near such active, submarine volcanoes located near populated parts of the Pacific.
One of the largest explosive volcanic eruptions in recent decades occurred on January 15, 2022, at Hunga Tonga–Hunga Haʻapai volcano in the Pacific Ocean, in the Kingdom of Tonga. It generated world…
2nd G-Ever international symposium and the 1st IUGS & SCJ international workshop on natural hazards
Background:
Asia-Pacific Region is an area with high risk of catastrophic natural disasters such as earthquakes, tsunami and volcanic eruptions. In today's highly globalized economy, when a disaster occurs it can create unpredictable turmoil not jus…
This report provides an assessment of the achievements and progress made in disaster risk reduction (DRR) by Tonga during the International Decade for Natural Disaster Reduction (IDNDR). It describes country’s recent experience with natural hazards and disasters, such as cyclone and volcano, also presents national institutional and legal framework for D…
This paper presents the results of interviews and surveys conducted with organisational stakeholders and scientists in New Zealand which explored how probabilistic volcanic hazard map properties influence map interpretation, understanding, and preference. The research's results suggest that data classification, colour scheme, content, and key expression…
This report presents the institutional and legal framework for disaster risk reduction in Western Samoa, and describes its common disaster risks and natural hazards, such as drought, earthquake, cyclone and volcano. It outlines the strategies, plans, projects and activities related to disaster prevention and risk management.
The report provides an eval…
This report reviews the progress made in addressing the vulnerabilities of Small Island Developing States (SIDS) through the implementation of the Mauritius Strategy, which includes natural and environmental disasters as one of its themes and means of implementation. It addresses their increased vulnerability due to climate change, the global financial…
This map illustrates Vanuatu's exposure to seismic, volcanic and tropical storm hazard.
Earthquake intensity zones indicate where there is a 20% probability that degrees of intensity shown on the map will be exceeded in 50 years; tropical storm intensity zones indicate where there is a 10% probability of a storm of this intensity striking in the next 1…
This map illustrates Fiji's exposure to seismic, volcanic and tropical storm hazard.
Earthquake intensity zones indicate where there is a 20% probability that degrees of intensity indicated will be exceeded in 50 years; tropical storm intensity zones indicate where there is a 10% probability of a storm of this intensity striking in the next 10 years.…
