Ellison needs to bone up on Long Run out Landslides off the Coast of Hawaii
He needs to take a moment of his busy day to research Long Run Out Landslides off the coast of Hawaii; from which he will discover that there is a long history of gigantic landslides off the Hawaii islands, any one of which would have eliminated the human population . . . if there had been any at the time. That the strip of land (45 miles long by 14 miles back up from the sea shore) below the Hawaiian Volcano Observatory is sliding towards the surrounding ocean, as until recently, the associated volcano's have been adding ~ 1 million tons of lava to that area every day since the early 1980's. https://www.livescience.com/25293-hawaii-giant-tsunami-landslides.html
