World's deepest breakwater couldn't withstand 600mph momentum of tsunami


"The massive tsunami that laid waste to the world's deepest breakwater on March 11 carried with it a momentum equal to that of 250 jumbo jets flying at 1,000 kph (600mph), according to calculations by a Waseda University ocean engineer. The two-kilometer-long breakwater at the mouth of Kamaishi Bay, Iwate Prefecture, was completed in 2009 and recognized by Guinness World Records as the deepest breakwater in the world."


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.
