This dataset contains preliminary impact assessments of the Hunga-Tonga-Hunga-Ha'apai volcanic eruption and induced tsunami in January 2022.
The eruptions sent a plume of ash, gas and steam 20 kilometers (12.4 miles) into the air. Satellite imagery showed a massive ash cloud and shockwaves spreading from the eruption. Ash was falling from the sky in the Tonga capital, Nuku'alofa, Saturday evening and phone connections were down. The eruption was likely the biggest recorded anywhere on the planet in more than 30 years, according to experts.
Tropical Cyclone (TC) Pam made landfall in Vanuatu on 13 March 2015, causing severe damage to parts of the country. A post-disaster needs assessment (Esler 2015) completed less than a month after the cyclone highlighted the need for multi-hazard mapping of urban areas and for an action plan to identify safe areas for future growth. The report also emphasised the importance of having a sound scientific basis for predicting hazards and a reliable forecasting system.
