Synopsis (short abstract) On the 15th January 2022 the underwater Hunga Tonga–Hunga Haʻapai volcano, located in the north of Tongatapu (the main island of Tonga), erupted following several minor eruptions over the previous weeks. It was reported as the largest recorded eruption in the past 30 years. On 14 January 2022, the Tonga Geological Services issued an alert of the Hunga Tonga Hunga Ha’apai volcanic activity and a tsunami marine warning. The powerful eruption subsequently resulted in a tsunami in Tonga and the surrounding region, with effects reaching countries including Fiji, America Samoa and as far as Chile and Peru. With around 86 percent of Tongans engaged in agriculture, the impacts of the eruption and tsunami may have impacted all agriculture sectors, including fisheries, crops and livestock. The volcanic plume reached 30 km into the atmosphere, releasing volcanic gases and aerosols that were subsequently carried over neighbouring countries, potentially impacting public health and the environment. The Government of Tonga declared a state of emergency on 16 January 2022.

Hunga Tonga–Hunga Ha’apai Volcano Eruption: Data in Emergencies Hazard Impact Assessment (DIEM-Impact) – Update No. 2

2022

Also available in:

No results found.

The Food and Agriculture Organization of the United Nations (FAO) established Data in Emergencies Hazard Impact Assessment (DIEM-Impact) to provide a granular and rapid understanding of the impact of large-scale hazards on agriculture and agricultural livelihoods, using a variety of assessment methodologies, including primary and secondary information, remote sensing technologies and FAO’s damage and loss methodology. The Hunga Tonga–Hunga Ha’apai undersea volcano in the Kingdom of Tonga erupted on 15 January 2022. The eruption resulted in two events with potential impact on agriculture livelihoods and all agriculture sub-sectors: (i) a volcanic ash cloud; and (ii) a tsunami. The Government of Tonga declared a state of emergency on 16 January 2022. This is FAO's Hunga Tonga–Hunga Ha’apai Volcano Eruption DIEM-Impact Update No. 2. It presents initial post-disaster observations and recommendations that humanitarian actors can use to assess the situation and plan emergency data-driven livelihood support.

The Hunga Tonga-Hunga Ha’apai (HT-HH) undersea volcano in the Kingdom of Tonga erupted on 15 January 2022 at 17.10 hours local time in a blast that was felt across the world. As a result of the eruption, the Government of Tonga declared a state of emergency on 16 January 2022. The eruption resulted in two events with potential impacts on agriculture livelihoods and all agriculture sub-sectors (crops, livestock, fisheries and aquaculture and forestry): a volcanic ash cloud and a tsunami. The Ministry of Agriculture, Food and Forestry and the Ministry of Fisheries, together with FAO, conducted a Volcano Eruption Household Impact Survey. Data collection was facilitated by Mainstreaming of Rural Development Innovation (MORDI) Tonga Trust, a national partner for project implementation. The household survey was conducted in the three most impacted divisions – ‘Eua, Ha’apai and Tongatapu. A total of 854 households were interviewed across the three divisions. The data collection process was challenged by various issues, including movement restrictions due to COVID-19 lockdown. This impact report outlines the findings of the survey and proposes medium- and long-term recommendations.

Hunga Tonga-Hunga Ha’apai eruption and tsunami 2022 – Damage and loss in the fisheries and aquaculture sector

The Hunga Tonga-Hunga Ha’apai undersea volcano in the Kingdom of Tonga erupted on 15 January 2022 at 17.10 hours local time in a blast that was felt across the world. As a result of the eruption, the Government of Tonga declared a state of emergency on 16 January 2022. The eruption resulted in two events with potential impacts on agriculture livelihoods and all agriculture sub-sectors (crops, livestock, fisheries and aquaculture, and forestry): a volcanic ash cloud and a tsunami. The Ministry of Fisheries (MoF) in Tonga released an initial damage report on 1 February 2022, with a focus on damage to fisheries assets covering small-scale, tuna and snapper vessels, and their engines and gear. The total estimated damage for the fisheries and aquaculture sub-sector was TOP 10.85 million (USD 4.932 million). This report complements the MoF damage report, with an emphasis on associated losses in the fisheries and aquaculture sector as a result of the volcanic ash cloud and tsunami events.
