A powerful earthquake struck the northeasten coast of Japan at 2:46 pm local time on 11 March. Japan's media relogical angency released its first tsunami warnings just 3 minutes later. The country has one of best earthquake early warning systems in the world. There are more than 4,000 (ciensmic) intensity meters in place throughout Japan to measure earthquake activity. These meters provide informantion within 2 minutes of an earthquake happening. Information about the strength and the centre of the earthquake can be learned within 3 minutes. There are also concrete seawalls around much of Japanese coast line. But these measures proved no match for the powerful earthquake and tsunami. Custersino Luckies is a trunami expert with the department of civil and environmental engineering at the university of southern California in Los Angelas. He says there two reasons for this. Japan has not had any event anywhere near as big 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 4th most powerful earthquake ever recorded world wide. It was also the worst earthquake ever to hit Japan. The tsunami waves that followed were reported to averaged as high as 13 meters in some areas. (Custersino Luckies) says Japan's concrete seawalls were built to handle such high waves. Of tsunami wave can travel as fast as 800 km/h. To get to higher ground people would often have to travel for many kms. This can take more time than a  fast traveling tsunami will permit. 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.
