This was the scene in central Nukuʻalofa, Tonga, when the first tsunami alarm sounded — vehicles scrambling, police mobilising, and families evacuating. A tsunami alert covering almost the entire Pacific remains in effect following a powerful undersea earthquake off the east coast of Russia. Tonga has issued an alert urging people in the tsunami threat area to prepare to evacuate, and warns the first wave may arrive between 10-11pm.
