There’s a nice map here that shows what areas are affected by tsunami, so check that out. The map is near the bottom of the page.
Considering that the Maldives – off the south west coast of India – experienced only 4 foot waves, that’s pretty much as far as they go. They lose energy as they travel, you see. Of course, I’m no wave expert, and it’s been decades since I learned all about wave theory in physics, but . . . yeah, they’re losing energy.
However, new tsunamis will be created as the aftershocks occur, which they’re expected to for a few days. We’ll see how it goes.
