What's the scariest natural disaster footage you've ever seen?

Made the mistake of going down the rabbit hole of a couple of heavily video documented natural disasters recently and my algorithm is flooded with them (no pun intended)...

What video documented natural disaster fascinates or horrifies you the most? For me it's probably the 2011 Japanese tsunami. The videos from that event are absolutely mind blowing. What made this tsunami so scary was how quickly and stealthily the sea level rose without it being obvious until it was too late. Then once the sea level topped the sea protective sea walls in many of the harbors the massive surge with even higher waves on top followed sending a massive powerful raging river of water well inland sweeping homes, large buildings, huge ships, and mountains of debris raging throughout the city. Can't imagine how horrifying it would have been first and most obviously to the unfortunate people caught up and swept away and then to the survivors who watched their city being totally destroyed knowing their homes and businesses were being destroyed and knowing many of their family members and friends were being killed. Can't imagine some of the horrible things survivors saw in the immediate aftermath of that disaster.

On a personal level, I didn't lose any property or loved ones in either the April 27th, 2011 Super Outbreak or Hurricane Katrina like some of you on TD did but I did have family and friends who lived in both those areas when those two disasters occurred. My father lived near Lake Tuscaloosa during the 2011 Super Outbreak and although he and I weren't personally affected he did an impromptu ride along to relieve a firefighter/first responder whose wife was going into labor a couple of days after the Tuscaloosa tornado and actually helped carry 3 dead bodies out of one of the hard hit neighborhoods off 15th street. He wasn't ready for that obviously and broke down in tears heading home that night. I went up to Tuscaloosa a few days to donate some supplies and was shocked by the level of damage I saw.

My brother and SIL lived near Destrehan during Katrina and fortunately only had minor damage and no flooding where they were. They left and went to stay with family in Florida during the hurricane so they didn't experience the storm itself. My brother met my dad in Alabama and the surreal part was them having to detour way out of the normal way back from Tuscaloosa to the Destrahan area via Jackson, MS and I-55 instead of the normal route down I-59 via Hattiesburg due to I-10 being impassable in New Orleans and them carrying weapons in case of any potential looting in my brother's neighborhood. The surreal part was remembering what my brother told me only a few months earlier when we had stopped at a Rouses between New Orleans and Metairie on the way home from the French Quarter Festival that day. I asked him what that area would look like if/when "the big one" hit and he said the parking lot we were in that day would be under several feet of water and it wasn't a matter of if that would happen but when. It still gives me chills knowing that it actually happened only a few months later.

P.S. The 2004 Indian Ocean tsunami was far deadlier and is the deadliest natural disaster ever documented but there aren't nearly as many videos of that disaster as there are of the 2011 Japanese tsunami.
