Tonga volcano: effects in Hawaii

[TomK]

Thanks TomK, the chart graphing the shock wave really shows the power of the eruption.

Here's a video visualization of the event fanning out across the Pacific, with Hawaii top right.
Translation from the Japanese website:
Himawari 8 band 8( 6.2 μm from 16:10 to 20:50 on January 15) Taking the difference (10 minutes) between the front and back frames from the image of the upper water vapor, it is 20:00 Japan time. The arrival of the sonic boom (?) due to the volcanic eruption of the Tonga Islands around 40 minutes could be visualized. What is interesting is that you can see the patterns of concentric circles in multiple layers.

Thanks. The shock wave was detected as far away as the UK, roughly 12,000 miles away (I need to check the actual distance). The tsunami was felt throughout the Pacific Ocean although fortunately wasn't too destructive, although it certainly was in Tonga. Hawaii was fortunate in this case, I'm not sure why the tsunami was so weak here but suspect it had a lot to do with underwater topography between Hawaii and Tonga.
