Seismologists discover evidence of a similar tsunami that hit Sendai in 869 AD.
The devastation wraught by the disaster that hit Japan on March 11, 2011 has been nothing less than horrific, but evidence of a similar tsunami event in 869 AD has lead at least one seismologist to conclude that a tsunami of this size could happen on average once every one thousand years.
It is not unusual for undersea earthquakes to generate tsunamis in this part of Japan. Offshore quakes in the 19th and 20th centuries also caused large walls of water to hit this area of coastline. But previous research by a Japanese team shows that in the 869 "Jogan" disaster, tsunami waters moved some 4km inland, causing widespread flooding.
