Sendai stands, but "not functioning"

The shaking continues in Sendai as aftershocks rock the already-ravaged city in northeast Japan.

CBS News Correspondent Bill Whitaker reported the aftershocks are still quite strong - six and above on the Richter scale - and frequent.

Whitaker said the devastation goes on for "miles and miles and miles."

When asked by co-anchor Erica Hill about the buildings in areas that look less affected by the earthquake, Whitaker said the city looks like it's functioning, but it's not.

"You can drive through some of the main streets downtown, and it looks like a functioning city," he said. "But then you look a little closer, the lights that are on are emergency lights, run by generators. Most of the city is still without water. Most of the city is still without telephones. We were talking to a person today who was saying that they have no Internet connections. He doesn't know what's going on, not only in the outside world, but what's going on right here in his own city. So, as I say, there are large portions of the city that are still standing, but the city is not functioning. And it's going to take quite some time for them to even get that portion of the city back up and running."

Hill asked if warning systems are still in place and how information is being disseminated.

Whitaker said, "There are lots and lots of sirens going off all the time around here today. There was a tsunami warning today, and there were reports on the radio, people were walking around with transistor radios, they were hearing it on the radio. There were helicopters flying overhead. People's loudspeakers and bullhorns. They're getting the word out when there's an emergency like that and many people heard that tsunami warning and they ran to get to higher ground. People are sort of skittish here. You can't blame them. But, as soon as they hear another rattle of the earth, or a warning of a possible tsunami, they get scared and they run to higher ground."
