Paragraph 2
The volcanic eruption sent atmospheric
waves and tsunami
around the world. It also caused sonic booms that
heard 10,000km away in Alaska. The eruption even lifted
in the sky above the UK, which is 16,500km from Tonga. Scientists in the UK reported the
disappearance of clouds as they moved higher into the atmosphere. UK
Professor Giles Harrison said the
was "a remarkably interconnected
". He said: "What happens on one side of the
can [spread] around to the other side at the speed of sound." NASA has said the volcano's
also reached space and could have affected the weather in space.
