Hunga Tonga Hunga Ha’apai
🕑 Added 2023-01-13 03:07:29 +0000 UTCApproximately 1 year ago, the Hunga Tonga Hunga Ha’apai (on January 15th 2022) generated a powerful plinian eruption. This obliterated much of the existing volcanic island. Well, I have several videos upcoming (as I just got permission) which cover what the remains of this island now look like. From up close! (I didn’t film it but someone who did has granted me permission to use it). Any questions?

I am unsure what exactly the mud might be from a rock perspective.

Some articles about the then new island from before it was destroyed mentioned that its beaches were made of sharp tephra and some kind of sticky mud. Like they really emphasized how weirdly sticky it was. My guess is that the mud was some kind of clay made by the weathering of the tephra in seawater, but what type of clay exactly? Something like bentonite? Was its stickiness a result of it being very freshly weathered, i.e., not yet settled and compacted into denser sediments? Thanks!

Things I'd like to see/know: * Other islands with similar potential * How long volcanic islands of varying types tend to last before the sea reclaims them * Compare-and-contrast with other similar oceanic explosive events (i.e. Krakatoa, Santorini) with regard to tsunami factors, ash effects, repeating events, etc.... a bit more depth than VEI analysis. * New lessons learned from this event specifically Thanks!
