Huge_Tonga_volcanic_eruption_felt_around_the_world_999.html

" A massive volcanic eruption in Tonga that triggered tsunami waves around the Pacific caused "significant damage" to the island nation's capital and smothered it in dust, New Zealand Prime Minister Jacinda Ardern said Sunday.

The eruption Saturday was so powerful it was recorded around the world, triggering a tsunami that flooded Pacific coastlines from Japan to the United States."

USGS estimates the magnitude was 5.8. The on-going routine activity in Hawaii usually registers between 3-3.5. The scale is exponential, though.
