This is the VOA Special English Technology Report.
A powerful earthquake struck the northeastern coast of Japan at 2:46pm local time on March 11th.Japan's Meteorological Agency released its first tsunami warnings just three minutes later.

The country has one of the best earthquake early-warning system in the world.There are more than 4,000 seismic intensity meters in place throughout to measure earthquake activity.This meters provide information whthin two minutes of an earthquake happening.Information about the strength and the center of the earthquake can be learned within three minutes.

There are also concrete sea walls around much of the Japanese coastal line.But these measures proved no match for the powerful earthquake and tsunami.

CS is a tsunami expert with the Department of Civil and Enviromental Engineering at the Universith of  Southern California in Los Angeles.

CS,Japan is one of the most well-prepared countries on earth in terms of tsunami warnings.They had a warning,but I think what was wrong is they had not anticipated the size of this event.

He says there are two reasons for this.Japan has not had any event anywhere near as biggest as this one in the last 150 years.And scientists had not expected such a large earthquake happening off the coast of Japan.The 9.0 magnitude earthquake was the fourth most powerful earthquakes ever recorded worldwide.It was also the earthquake ever to hit Japan.The tsunami waves that followed were reported to have reach as high as thirteen meters in some areas.

CS says Japan's concrete sea walls were not to build to handle such high waves.

CS,The concrete sea walls in many places in Japan about 10 meters for this about 33 feet,in the Sendai they were about three meters,that's about 10 feet.So that's shows you that at least in that area they were not expecting a such sizable wave.

A tsunami wave can travel as fast as eight hundred kilometers per hour.To get to higher ground,people would often have to travel for many kilometers.This can take more time than the fast travelling tsunami will take.This is especially true in cases like Japan where the center of the earthquake struck 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 earthquakes and tsunamis can be predicted.
