Many of you have heard various reports of the power of the earthquake. I've been collecting what I've heard and read. I will quote sources whenever possible.
- The earthquake shifted the planet on its axis by nearly 4 inches (10 centimeters) and moved the main island of Japan by 8 feet (2.4 meters) towards the east.
- The energy released in the earthquake was 200 times that of the Kobe earthquake in 1995 (M7.3) that killed more than 6000 people.
- The tsunami were as high as 10 meters (33 feet) with a speed of about 800 km per hour.
- The earthquake bent the tip of Tokyo Tower, the 1,093-foot Eiffel-like structure that has stood as the symbol of Japan’s postwar rebirth for half a century. For the first time since it was erected in 1958, the tower no longer points directly upward
- The NY Times created a map showing the areas of damage.
- The total cost of this disaster has been estimated at US$200-300 billion.
