Impacts and Damage Assessments - Hunga Tonga-Hunga Ha'apai 2022 Volcanic Eruption

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.

These are preliminary analysis detected from Pleiades images and have not yet been validated in the field

Sources for each study are mentioned in the description of each resource.
