WELLINGTON, New Zealand (AP) — The tsunami threat around the Pacific from a huge undersea volcanic eruption began to recede Sunday, while the extent of damage to Tonga remained unclear. In Tonga it sent tsunami waves crashing across the shore and people rushing to higher ground. The capital, Nuku’alofa, was covered in a thick film of volcanic dust, Ardern said, contaminating water supplies and making fresh water a vital need. The Tonga Meteorological Services said a tsunami warning was declared for all of the archipelago, and data from the Pacific tsunami center said waves of 80 centimeters (2.7 feet) were detected. U.S. Secretary of State Antony Blinken wrote on Twitter he is “deeply concerned for the people of Tonga as they recover from the aftermath of a volcanic eruption and tsunami.
