There are over 2,700 active artificial satellites orbiting Earth as of now, and many of them are equipped with advanced cameras. Some managed to capture amazing footage of an underwater volcano that erupted in the South Pacific kingdom of Tonga, or more specifically, on the island Hunga Tonga-Hunga Ha’apai. The eruption sent ash plumes up to 12 miles into the air, stretching to have a radius of over 161 miles thus far.
The Tonga volcano eruption was so powerful that the space satellite not only captured the massive ash cloud, but also an atmospheric shockwave that radiated out from the volcano at close to the speed of sound. This shockwave was reportedly heard as far as 1,430 miles away in New Zealand, and the tsunami caused waves that were seen all the way in California.

The concern at the moment is how little information we have and that’s scary. When the vent is below water, nothing can tell us what will happen next,” said Janine Krippner, a New Zealand-based volcanologist with the Smithsonian Global Volcanism Program.
