The huge volcanic eruption in the Pacific island nation of Tonga could cause long-lasting damage to coral reefs, erode coastlines and disrupt fisheries, scientists studying satellite images have warned.

Hunga Tonga-Hunga Ha’apai, an undersea volcano, erupted on Saturday triggering tsunami warnings across the Pacific. In the first official update, Tonga’s government on Tuesday said multiple people have been injured and three have died.
