Displaying 15 of about 988 resultsCan a volcano erupt after tens of thousands of years of dormancy? If so, how can this be explained and what makes volcanic eruptions more dangerous, i.e. explosive? These are key questions in volcanic hazard assessment and can also draw attention to volcanoes that appear to be inactive. Even in a quiet dormant phase, a volcano can rapidly become active…
[...]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…
University of Queensland researchers have optimised a new technique to help forecast how volcanoes will behave, which could save lives and property around the world.Dr Teresa Ubide from UQ’s School of the Environment and a team of international collaborators have trialled a new application of the tongue-twisting approach: laser ablation inductively coup…
This Natural Disaster Risk Reduction Educational Kit (NDRR) in Arabic has been developed with the view to enhancing the coping capabilities of disaster prone communities in the Arab States region as well as the dissemination of the technical knowledge in natural disaster reduction to build the capacities of educational institutions, students, and teache…
This booklet was elaborated as "questions & answers" between a volcanologist and a volcano. It teaches children what a volcano is, the different types of volcanoes, and their level of risk. Then prevention is featured as a game, and instructions follow to be applied in emergency situations. This booklet includes several notes for parents and teacher…
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…
An international team has used satellite- and ground-based ionospheric observations to demonstrate that an air pressure wave triggered by volcanic eruptions could produce an equatorial plasma bubble (EPB) in the ionosphere, severely disrupting satellite-based communications. Their findings were published in the journal Scientific Reports.The ionosphere…
Time11:00 - 12:00 AM (GMT+12)AboutAre we prepared for disasters? 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…
Indonesian scientists fulfill the need for earthquake education on islands replete with tectonic-related hazards, starting with North Sulawesi. Indonesia is an archipelago that consists of 18,108 islands that straddle the Pacific and Indian oceans. Most archipelagoes, including Indonesia, are formed when tectonic processes generate a chain of volca…
This case study follows this collaboration from initial discussions and workshops, through to the use of SCOPE in various disaster responses in the Philippines, and to WFP’s local government capacity strengthening and its ongoing role helping the Government develop its own beneficiary management system. Providing food and cash assistance to populations…
Detailed analysis of the January 2022 event shows how underwater blasts generated huge waves that battered coastlines throughout the island nation.The events following last year’s massive eruption of an underwater volcano in the island nation of Tonga have been reconstructed in a simulation that captures how the resulting tsunami spread throughout the r…
El Volcán Sangay es uno de los volcanes más activos del país y los primeros reportes de sus erupciones datan del año 1628. Es importante conocer los posibles impactos de la actividad volcánica en nuestras comunidades. Así, la caída de ceniza es el principal fenómeno de las erupciones del volcán Sangay que afecta a las comunidades de los cantones de Guam…
Esta guía ayuda al proceso de formación con un lenguaje adecuado a las y los participantes de comunidades del Ecuador, a fin de fortalecer sus conocimientos generales sobre el tema y contar con un equipo de personas voluntarias comprometidas con el tema en diversas localidades del país. Para ello es fundamental que el proceso de formación sea muy horizo…
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…
Benthic foraminifera from the South China Sea were studied to assess mass mortality and to monitor the composition and recovery of the benthic communities following the 1991 Mt Pinatubo ashfall. Surface distribution data from monitoring stations in the eastern South China Sea that were occupied during four cruises between spring 1994 and summer 1998 dis…
