Another Japanese Tsunami

Japan's east coast, hit in the spring of 2011 by a big tsunami, has been hit again. This time, the tsunami was much smaller. The earthquake measured 7.1 on the Richter scale, 10 km below the sea surface at a distance of about 320 km from the coast. The tsunami that reached the coast was not higher than 30 cm. This was a relief. Not all tsunamis are devastating. Still, one hopes the lesson is learned from the last big one, because eventually, there will be more big tsunamis. Perhaps not in the next decade or so, but sometime. There must be better protection for humans, dogs, nuclear power plants etc.
