So, here was my original plan for this weekend: post a pictures of some of the proposed megatsunami chevrons as this week’s Geopuzzle, and then on Monday repost Return of the Megatsunami together with a new post which details some interesting new developments in the tale. Sadly, Ron scuppered that plan by using the Madagascar Chevrons in Where on Google Earth (even more annoyingly, even though I knew exactly where the damn things were, Lab Lemming beat me to it).
So instead, I’ve decided to try something a bit different, which may or may not work. I’m proposing that we go on a chevron hunt – how many of these things can we find? Are they just distributed around the Indian Ocean, or are they found around other ocean basins? Can we get an idea of sources from looking at their distributions? It could be an interesting exercise.
As a starting point, I’ve created a Google Map which shows the locations of the pictures from my repost (which I’ve put up early for reference), and Burckle Crater.
Have a look around on the map, or in your version of Google Earth, and see if you can find any other examples. Post their locations in the comments below, and I’ll add them onto the map (with full credit to the discoverers, of course).
Go!
