This astounding video came to my attention via an email yesterday. It's yet another view of the awesome destructive power of the tsunami that arose from the Japan earthquake of March 11, 2011. The video was taken from a hillside in the resort town of Minami-Sanriku. It's amazing the kinds of events our modern technology allows us to witness.
This video is definitely strange. It was taken in Tokyo Central Park on the afternoon the magnitude 9.0 earthquake struck in northern Japan. What it shows has been described by some as liquefaction. I'm not sure that's what's going here but whatever it is, I think most people would find it very unsettling. That doesn't seem to be the case with people in the park.
Be sure to watch it past the first minute (and the constantly barking dog) as that is when it gets the most interesting.
GPS positioning data is showing that the island of Japan has moved an incredible 13 feet closer to North America due to Friday's 8.9 earthquake (some are now upgrading it to a magnitude 9.0). It also shows some 250 miles of Japan's coastline dropped 2 feet. This New York Times page has some great multimedia graphics about the geology involved with the quake. The first is a series of seven graphics that clearly illustrate the plate tectonics involved in the devastating earthquake and subsequent tsunami.
