Why did the sea receded in Sri Lanka during the Asian Tsunami?
I watch a lot of documentaries about these sorts of things and I’ve never heard of the sea NOT receding before a tsunami strikes. It is inevitable that the sea would recede because, in deep water, the tsunami is just a wave. You wouldn’t be able to notice any difference if you were in a boat miles from the shore; however, the closer you get to shore, the shallower the water gets and the taller the wave grows. The tsunami is primarily ENERGY in the form of a wave moving very fast and when it’s squeezed into shallow water it sucks all of the water ahead of it into itself so it won’t lose energy. The sea receding has nothing to do with the trough or the crest and whatever program you learned that from was mistaken. Every wave in the world crashes on a beach somewhere….and for the same reason. If there weren’t beaches the waves wouldn’t crash and they would continue on. But when they hit shallow water, they suck water into themselves from the beach and break, just to be sucked back into
