mizawa is an associate prop soar at kyoto university's disaster prevention research institute. he analyzed data from hundreds of seismographs across japan immediately following the earthquake. the results showed about 80 separate jolts occurred within about 15 minutes of the original quake. the red here indicates the areas that were shaken. we can also get an idea of the size of these tremors. many of them were small with a magnitude of around 2.0. but seismographs also measured a quake with a magnitude of 4.7, which is considered relatively strong. the earthquake that was 1,300 kilometers from the epicenter of the march 11th tremor was observed in southwestern japan. a giant earthquake off sumatra island in 2004 is also known to have triggered smaller quakes. but researchers say the ones that happened on march 11th were unprecedented in scale and number. >>> people are getting ready for the first anniversary of the disaster that changed life across the country. we're bringing you a series of stories called "lessons of march 11th one year on." the magnitude 9 earthquake trigger

researchers from jamstak and kyoto university will be on board. they'll examine the seabed 220 kilometers off the peninsula in miyagi prefecture. the plate in the area moved 50 meters when the quake occurred. >> translator: we'd like to study how the plate moved so much and how the tsunami occurred. we want to learn lessons for the future. >> researchers will lower the drill 7,000 meters below the surface of the ocean and then dig 1,000 meters into the japan trench. they will collect rock samples from the seabed. they'll also gauge the temperature to calculate the energy generated from the sliding plates. >>> japanese engineers are looking toward the moon 40 years after the u.s. apollo space program came to an end. they want to explore its surface. robots could be the key. >> reporter: for a robot, it's a long way from the sand dunes of hamamatzu to the surface of the moon. but recent tests represent a first small step toward that goal. jaxa, the japan aerospace exploration agency, has been work with universities and private sector companies to de
