welcome back. this is "world one," live from london. >> coming up on 6:00 a.m. in new york, noon in berlin, 7:00 p.m. in tokyo. we want to tell you about a piece of equipment that's helping to inspect the fukushima daiichi nuclear plan the. >> it's a robot that's gone into one of the reactor buildings. it's 41 degrees and it's so humid, the robot's lenses fogged up. >> the machine was able to report relatively low radiation levels. >> japan is pretty used to earthquakes of the kind that damaged the nuclear plant. paula hancocks shows us the country is getting ready for a quake that could be even more serious than the one that just struck. >> reporter: once the ground starts shaking, you should get on the floor. if you can, crawl under a table or a december tock protect yourself from falling debris. all you can do then is wait until the shaking stops.
