Extra-terrestrial bodies do collide with Earth from time to time, sometimes with profound consequences. Witness the asteroid impact 65 million years ago that basically killed off the dinosaurs and wiped the slate clean for mammals to take their turn. No idea of how high the waves were, but they were big enough, and that was just the beginning.

We can assert that such events can happen, and probably will happen, given enough time. On the scale of human lifespans, the probabilities of such cataclysmic events is quite low, while the chances of more mundane disasters like fires, floods, earthquakes, winter storms, etc. is much more likely and well worth the time and effort to prepare. It all comes down to the math...

Welcome, Pooh-Bah Jeanette-Isabelle! What a great speech!

Great advice, hikermor! Geezer in chief strikes again!

For comparison, it appears the tsunami resulting from the Krakatoa eruption in 1883 were 40 meters tall (= 131 ft). I'm guessing a 400' tsunami requires not just 3 times as much energy, but an exponentially greater amount. I guess if I were in the path of such a tsunami, I'd just try to take a selfie with the incoming tsunami and post it online before I die.

I would watch out for the warning signs.

Those dolls would all fit into a couple of 5 gallon buckets - which are water tight with the right lids.

As for the photos, have them scanned and digitized then keep on a USB key or email them to yourself and perhaps another family member or close friend. If the originals ever get damaged, lost or whatever, you can always print then re-frame when needed.

There is an island in the eastern Atlantic (one of the Canary Islands?) that they think will cause a tsunami if the mountainside collapses. Something about the geology increases the chance. It's been too many years since I watched the show about the island to remember details.

Yeah, the island is La Palma, and the Cumbre Vieja volcanic ridge.

Speculation is if it blows the landslide into the ocean would create a mega tsunami, hitting African coast in an hour, UK in 3.5 hours and the eastern USA in 6.

Thanks. Good read at: ... wiki/Cumbre_Vieja. The mega-Tsunami discussion is toward the bottom. If the Cumbre Vieja ridge fails as per the model, it would not be a good time to be standing on the beach between Key West and Bangor, Maine. However, there are folks who don’t see evidence that it will fail catastrophically and will instead be a slow slide into the sea. It’s worth reading.

more nonsense that was put out as click bait or to increase the sale of bottle water and what ever.look at the link by a guy who makes his living studying land slides.he was on the ground there and debunked that disaster claim.
scroll down for his on site photos and evaluation.
great stuff about real slides and the outcomes.

Thanks for the landslide blog link. While Rattlesnake Ridge is fascinating, I was really interested in his discussion of the Montecito Mess, with which we are now grappling.

Problems include where to put the huge amount of debris now clogging the town and highway 101, which might be open by Monday, if everything works out. Complications include separating toxic materials from the waste, as well as looking for the remains of at least three individuals who remain missing. Crews are working 24/7 to clear debris basins and culvert etc. before the next major storm, which fortunately is a ways off. Our local fairgrounds, 30 miles from Montecito is holding some of the debris for sorting and evaluation.

The models predicted a big problem if the burned watersheds received rain at a rate of 1/2 inch in an hour. During the event, one rain gauge recorded 1/2 inch in five minutes.

Mother Nature bats last....
