Displaying 75 of about 135 resultsThe January 2022 eruption of Hunga Tonga–Hunga Ha‘apai was among the most powerful ever recorded. It generated atmospheric shock waves that circled the globe several times, and its impacts claimed the lives of six people, including two in Peru, 9,600 kilometers away from Tonga.
In the aftermath of the eruption, social media videos depict…
A series of six weekly lectures starting 17 July
The last two years brought the unpredictable nature of New Zealand’s natural and man-made hazards to the fore. Christchurch’s major earthquake and its devastating aftershocks, the Pike River mine disaster, the Rena oil spill, heavy rain and snow falls, tornadoes and other unexpected events overstretched…
This conference will offer a world class technical program encompassing traditional IGARSS topics and new topics reflecting the theme of the 2013 conference, "Building a sustainable earth through remote sensing." The theme was selected to emphasize the issues that most affect the Earth's environment, and the human impact on the planet.
The conference w…
It’s been a month since the Hunga Tonga–Hunga Ha’apai volcano erupted and cut off Tonga’s domestic and international communications. While satellite providers rushed to assist with restoring a basic connection, local media report that current services meet only 12.5% of national demand.
It’s the second time in three years that Tongans have faced a comm…
In the wake of a violent volcanic eruption in Tonga, much of the communication with residents on the islands remains at a standstill. In our modern, highly-connected world, more than 95% of global data transfer occurs along fibre-optic cables that criss-cross through the world’s oceans.
Breakage or interruption to this critical infrastructur…
This paper presents Australia’s disaster risks and natural hazards, such as cyclone, storm, earthquake, flood, wildfire, drought and volcano, and discusses country’s institutional organization and disaster management system.
This report presents the institutional and legal framework for disaster risk reduction in Vanuatu, and describes its common disaster risks and natural hazards, such as earthquake, cyclone and volcano. It outlines the strategies, plans, projects and activities related to disaster prevention and risk management.
The report provides an evaluation of count…
This report presents the institutional and legal framework for disaster risk reduction in Papua New Guinea, and describes its common disaster risks and natural hazards, such as flood, drought, cyclone, earthquake, tsunami, wild fire, epidemic and volcano. It outlines the strategies, plans, projects and activities related to disaster prevention and risk…
This map illustrates New Zealand'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 n…
This paper examines the volcanic hazard map visualisation affects cognition and crisis decision-making. Hazard maps are used to communicate complex scientific data with many audiences during volcanic unrest crises, but it is unclear how common hazard visualisation styles affect cognition, behaviour, and decision-making. Here we use eye-gaze tracking and…
On January 14, 2022, the South Pacific experienced the incredible force of the submarine volcano Hunga Tonga–Hunga Haʻapai. The plume reached 30 kilometers into the stratosphere, and the eruption was heard across the South Pacific, Australia, New Zealand as well as in parts of the United States of America. The volcano ranks among the world’s biggest und…
This paper analyses the 2017-2018 eruption of Ambae volcano, Vanuatu, which caused the entire population of the island (~11,700 people) to be evacuated off-island, as this event presents a valuable opportunity to learn from a large-scale forced migration in a Pacific setting. Lessons from this event will advise and help to plan for future population dis…
An online tsunami awareness resource containing six chapters: (i) tsunami basics; (ii) Australian tsunami impacts; (iii) warning system; (iv) marine threat tsunami; (v) land threat tsunami; and (vi) preparing for tsunami. It also considers: earthquakes, landslides, volcanic activity and wind waves.
This disaster awareness poster, of interest to the general public and the school community, provides clear key messages to understand the main hazards and learn about the appropriate disaster preparedness and response behaviors. Five hazards are illustrated: cyclone, tsunami, earthquake, flood and volcano.
This poster has been elaborated by a project c…
The notes and activities in the Survival Island kit take the issue of six major natural disasters in the Pacific to the classroom so students can relate to them and learn how to tackle them.
This educational kit was put together under the 'Reducing Vulnerabilities Project for Pacific ACP States' funded by the European Union (EU) and implemented by the…
