Krakatau (Indonesia) in 1883. I found a big coffee table book about it years ago. More of a science book I guess but with lots of water colors, hand sketches, technical information and historical accounts. Some from ships that were nearby, accounts from locals, etc. Several photographs.
One photo was of a train that had been washed inland a huge distance (a mile?) due to the huge tsunami. I think the run-up from the wave was over 100 meters in some locations.
There was an entire section of the book detailing the tidal gauge measurements around the world, with tides in England being impacted by the eruption! And of course all the ash causing “the year without summer” throughout the world.
Polynesia. There are islands no higher than palm trees. Where they gonna run to.
Tidal waves achieve their power not as much from their vertical height, but more from the mass of water that drives it. the distance traveled inland is a function of that mass.
If I remember right. The largest eruption in the 20 century was Nova Erupta (SIC) in Alaska.
I am not going to do searches on the dam thing. Just what I remember with discussions with the geologist professors I used to know.
These guys chomp at the bit to get on one after its safe after an eruption to study minerals those things bring up.
