Infrastructure Damage but No Fatalities or Injuries Reported after Earthquake.
BALDWIN: So as we've been talking to people who live and have been describing to us on the air what it felt like, this 7.0 magnitude quake this morning in Anchorage, Alaska, we've really been watching, eavesdropping on this Facebook Live feed of our affiliate, KTVA, in Anchorage, Alaska. Everybody one has been knocked off the air. You can see the damage from the newsroom. But they've still been going over Facebook. Let's dip in and keep watching a bit.</s>UNIDENTIFIED KTVA REPORTER: cell phone back to its owner and get to work. Likely go out into the field and hopefully have a live report tonight. None of us really know what our shows are going to look like, what the structure is going to be, but we are all going to do something and work hard and hope that we can deliver the best product possible under the current circumstances. Again, I thank you for joining us. Hey, is John back there?</s>UNIDENTIFIED KTVA REPORTER: Yes, can someone take this? I have an assignment.</s>BALDWIN: Allison Chinchar, passing off the phone there. It looks like KTVA, different people are heading out on assignment trying to get out and get video of the damage out and about. What's the latest you're getting, Allison?</s>ALLISON CHINCHAR, AMS METEORLOGIST: Those aftershock numbers keep going up. We're now at 15 aftershocks we've had since the initial 7.0 quake. This is normal. You may not have that many this soon after. Sometimes it can take several hours before you tick up. This is a very decent amount of aftershocks after the initial quake. Some of those have been quite large. In fact, one was over five. And that was the one that was closest to downtown Anchorage. The concern is, after you get a quake that is a 7.0, a lot of buildings, infrastructure becomes structurally compromised. Any subsequent aftershocks can continue to do more damage. That's why we tell me, if anything's wrong with your building, get out. Even it's just the windows are broken or some cracks in the foundation. You don't know about the stuff you can't see. Get out of the building where you can be safer. One other thing, we talked about this, how far people were able to feel this. Getting some reports as far as 400 miles away. But it's not just life shaking. You have a lot of this area in yellow that indicates strong and very strong shaking. Then the orange area, closer to the epicenter, that's where you're talking about severe shaking. That makes a lot of sense when you see some of the video that shows some of the damage that's taken place already. One concern, the U.S. Geological Survey monitors economic impacts. They have given this a yellow pager, indicating they do expect some type of economic impact with the quake. Again, it's a large one. It was relatively shallow. I know it was only 25 miles underground, and that may seem like it's pretty far down, but you have to get over that 40-mile threshold before it's considered a deep quake. This one was not. This was still considered a shallow earthquake. Typically, when we talk about aftershocks, if you have an initial quake of 7.0, it's likely you'll get one that's a magnitude six or higher. At least 10 that could be five or higher. At least 100 that could be, say, magnitude four or larger. So the continuing threat for this particular earthquake is actually going to be those subsequent aftershocks that come through based off of that initial one that was a 7.0. Brooke, one other thing to mention, too, if you have travel plans there, keep in mind a lot of roads are damaged and the airport, the international airport is official on a ground stop as of now.</s>BALDWIN: That's right. Listening to the reporter of that TV station saying they all went through the 7.9 magnitude quake back in January. But everyone I've talked to and heard from said this one felt the worst and most violent they have ever felt. We'll come back to you, Allison, next hour. Thank you so much. We are also -- Allison mentioned the international airport in Anchorage, total ground stop, diverting flights. Also coming in, here's pictures as that quake happened from inside this airport. We're getting control tower audio. We'll play that for you as we see more and more images of widespread infrastructure damage in the Anchorage, Alaska, area. Breaking news after this.
