What's Happened Since the Tonga Eruption

The eruption of the Hunga-Tonga-Hunga-Ha'apai volcano on January 15th was huge. The nearby nation of Tonga was flooded by a tsunami, covered with volcanic ash, and cut off from the internet for days. What have we found out since then?

Scientific analysis has revealed the actual size of the eruption, and the massive number of lightning strikes inside it. We have a possible trajectory of the ash flung skyward. We have pictures from Tonga, which you would have thought were taken with black and white film if it weren't for the blue of the ocean. The eruption's shock wave traveled around the world four times. Astrum brings us up to speed on the Pacific eruption and what we've learned about it. The last minute of the video is an ad.
