This situation report released by the National Emergency Management Office (NEMO) is to inform operational partners on current situation of the secondary effects of the Hunga Tonga Hunga Ha’apai (HTHH) Volcanic eruption. This Situation report (Sitrep) covers the period stated above. Frequency of reports will depend on availability of new information and evolving operation.
This map illustrates effects of the Hunga-Tonga Hunga- Ha'apai volcanic eruption in Mango island and damage assessments as detected from a Kompsat-3 image acquired o 18 January 2022. UNOSTAT identified 26 structures as damaged and/or destroyed and 1 structure as potentially damaged. The entire island appears to be covered with ashes. This is a preliminary analysis and has not yet been validated in the field
Damage assessment as detected from a Pleiades image acquired on 18 January 2022 in Nomuka Island (Mu'omu'a district, Tonga).
260 structures identified, 52 structures were identified as damaged and/or destroyed, 13 as potentially flooded and almost all structures were covered with ash. This is a preliminary analysis and has not yet been validated in the field
This map illustrates the impact of the Hunga Tonga-hunga Ha'apai volcanic eruption and the subsequent tsunami in Fonoifua island located at 110 km NE of Nuku'alofa and also the building damage assessment as detected from a Pleaides image acquired on 20 January 2022.
Preliminary Satellite-Derived Damage Assessment as of 21st January 2022 for 'Eua Island.
Status:
The map shows landcover and vegetation impact of the Hunga Tonga Hunga Haápai volcanic eruption on the Tonga Island group.
Map showing reefs with in the different Impact Zones.
This is the Geojson format of the same data in shapefile.
This map identifies reefs that falls within each of the 3 Impact Zones
The folder contains GIS data for Eua Island acquired from UNOSTAT. Shapefiles are derived from Pleiades Sensor and World View 3 sensor with data available on Structures impacted (Points), Analysis Extent (Polygon), Cloud obstruction (Polygon) and Shoreline (Lines).

The primary aim of these guidelines is to protect the health of humans from threats posed by the recreational use of coastal, estuarine and fresh waters. Threats may include natural hazards such as surf, rip currents and aquatic organisms, and those with an artificial aspect, such as discharges of wastewater. These guidelines should be used to ensure that recreational water environments are managed as safely as possible so that as many people as possible can benefit from using the water.
