[Homework]SENEWS-2011-03-21
Castas Cinakos is a Tsunami expert with the department of civil and environment engineering at the universith of southern carlifornia.he sayes there are two reasons for these and has not had any event any when near as big as this one in the last 150 years.and scientists had not expected such a large earthquake happening of the coast of Japan.the nine point zero magnitude earth was the forth most powerful earthquake ever recorded worldwide.it was also the worst earthquake ever to hit Japan.The tsunami waves that followed were reported to have reached as high as 13 meters in some areas.Casteas Cinako says Japan's concrete seawalls were not built to handle such high waves.as tsunami wave can travel as fast as 800 kilometers per hour. to get to the higher ground , people would often have to travel for many kilometers. this can take more time than a fast traveling tsunami will permit.this is a especially true in cases like Japan , where the center of earthquake stroke so close to the coastline.the tsunami waves followed almost immediately . experts say early warning systems will continue to be limited by these facts until earthquake and tsunami can be predicted.
