Waves rush over island country while tidal surges are felt by small Pacific neighbours, New Zealand, Australia and US
Tsunami waves caused by an undersea volcano have flooded the Pacific Island country of Tonga, where entire towns have been inundated with water and scientists warn the main island could be blanketed in volcanic ash.
Videos shared on social media after the eruption showed people running for higher ground as the one metre high floods hit coastal areas and made their way farther inland while the sky darkened with ash.
