This is how satellite images show the eruption of the volcano in Tonga

Planet Labs has shared satellite images showing the lead up to last Saturday's massive eruption of the underwater volcano in Tonga. The satellite company said the island's surface appears to have expanded by 45% due to ash fall since volcanic activity began to increase in mid-December. On January 15, two hours before the eruption, you can see that a middle portion of the landmass is missing. The volcanologists explained that the great eruption could have been caused by the interaction of the water with the magma, which increases the explosiveness. The eruption prompted tsunami warnings and evacuation orders off the coast of Tonga, as well as several South Pacific islands, where images on social media showed waves crashing against coastal homes.

Telephone and Internet lines were also interrupted. this volcano. The Hunga Tonga-Hunga Ha'apai volcano has erupted regularly over the past few decades, but Saturday's eruption was so loud that residents of far flung parts of Fiji and New Zealand said they were able to hear it.
