Robert sent in the link https://phys.org/news/2025-05-ancient-amber-tsunamis.html … a deposit of amber has been found on Hokkaido Island in northern Japan. It is said the deposition was lodged in deep sea sediments which were later uplifted to become Hokkaido. Robert says, what if the deposition occurred instantaneously during a cataclysm? No elaborate take is then required to explain how terrestrial deposits were buried deep under the ocean and then uplifted later to become dry land. A tsunami wave is all it takes – washing over dry land and subsequently buried. However, the idea what was at the bottom of the sea became dry land is not unreasonable if the poles really did move. A change in the geoid of the earth would involve a redistribution of the oceans.
At the link the amber deposit is dated 115 million years ago – during early Cretaceous. The amber samples are deformed in a particular way that suggests that trees and plant debris were rapidly swept out into the ocean, eventually sinking to the sea floor. Amber is a fossilised tree resub. In this instance, the amber rich silica was found in a quarry.
