The blast sent tsunami waves pummeling across the Pacific Ocean and covered the island nation of Tonga in a thick blanket of ash.

Tonga, other countries, and aid organizations are still trying to assess the full extent of the damage.
Meanwhile, scientists are mapping potential atmospheric and environmental side effects that may come in the explosion’s wake.
The eruption is a “once-in-a-millenniumevent,” according to University of Auckland volcanologist Shane Cronin writing for CNN recently.

“The eruption was remarkable in that it involved the simultaneous formation of a volcanic ash plume, an atmospheric shock wave, and a series of tsunami waves.”
