Following the strong eruptions that pulverized a large part of the Hunga Tonga and Hunga Ha'Apai islands, and caused a tsunami, their collateral damage begins to be counted.
In the islands close to the eruptive site, many buildings and houses were destroyed. More than 80% of the inhabitants are affected.

An oil spill occurred on January 15 during the unloading of the tanker "Mare Doricum", from the Repsol company, at the La Pampilla refinery; the accident was caused by a violent swell. Oil has a significant impact on the coastal marine ecosystem, and poses risks to public health. Two protected natural areas are endangered to the north of the spill: the National Reserve of the system of islands and islets "over approximately 512 hectares" and the Ancon Protected Area "over 1,758 hectares".
The tourist chain and the world of fishing are impacted: 21 beaches are polluted and many species of fish are dead.
