The next-generation K supercomputer was ranked as the world's fastest computer in June and November 2011. A University of Tokyo research team has developed a system that will use a next-generation supercomputer to simultaneously predict tremors, tsunami and movements in the Earth's crust after a massive earthquake occurs.

The team, led by Takuto Maeda, an associate professor at the University of Tokyo's Center of Integrated Disaster Information Research (CIDIR), has used the new system on a current-generation supercomputer, which almost succeeded in reconstructing the aftermath of the Great East Japan Earthquake on March 11.

Predictions about tremors, tsunami and crust movements have been made separately in the past. But the system's simultaneous calculations are more likely to predict damage that would have been missed by separate findings, such as how a tsunami might impact an area where the ground level has sunk due to an earthquake.

Using the system, the team entered data of the March 11 earthquake, such as its magnitude and location, into the supercomputer. The supercomputer predicted seismic waves would occur throughout the nation within 10 minutes of the earthquake, a massive tsunami hitting coastal areas after about 30 minutes, and the subsiding of the Kanto and Sendai plains.

The system's usability was confirmed by its ability to make predictions that were very close to what occurred in the aftermath of the Great East Japan Earthquake. But the system was restricted by the processing power of the current-generation supercomputer. A large amount of data must be processed to simultaneously calculate crustal movements and tsunami. Current-generation supercomputers lack sufficient storage capacity to process these calculations, and therefore some data was skipped.

Despite this, the team has further developed the system to predict more accurate damage in anticipation for its use on the nation's next-generation supercomputer, known as K, which has a data storage capacity 100 times greater than the current generation, and will be available in autumn. As the system can be used to predict detailed damage caused by multiple disasters, the team is planning to analyze the effect of the simultaneous occurrence of three big earthquakes known as the Tokai, Tonankai and Nankai earthquakes.

Meanwhile, the University of Tokyo's Earthquake Research Institute is planning to develop another system for the K supercomputer from April that will analyze urban damage caused by earthquakes and tsunami, such as the collapse of buildings, and predict how certain regions should be evacuated. The research team also plans to collaborate with the institute.

According to Scripture the biggest earthquakes are still ahead of us. We haven’t seen anything yet!

Should we then tremble with foreboding and fright?

Not at all -- if we belong to God.

 Therefore will not we fear, though the earth be removed, and though the mountains be carried into the midst of the sea;
 Psa 46:2

Even if we stand at the cliff-edge of doom, we are fearless in Christ. He is well able to take care for us. Whether we live or die, we are His and to live is Christ and to die is Christ!

wow, how awesome is technology I hope they will be able to use it the way they intend to, because that will really help a lot of people. :D

And thank you so much towards the end of the news part I was beginning to feel a bit nervous. But when I read the last part about Christ I was completely uplifted. Thank you Sooo much ^_^

What a fascinating perspective! I'm sure you who are in Japan see all the Bible's references to earthquakes in such a vivid way. Loved reading your post and will be back. (I discovered you in Baptist Missionary Wives.) Bless you and your ministry.
