Transcript for Italy Hit By Second Major Earthquake in Seven Years
them. They were asleep. We want to turn to Dr. Lucy Jones, an expert in earthquakes for more on the threat in Italy and what we need to be prepared for at home. Dr. Jones, according to reports, the earthquake lasted for nearly 2:30. Is that unusual? I think that's an expression of how long people felt shaking. That probably includes some aftershock. A magnitude 6 is going to be on a fault about ten miles long and probably last about five or six seconds that the Earth is producing energy. That's interesting. This is the second major earthquake to hit Italy in seven years. You have called this area the California of Europe, yes? Right. It's just like in California -- the United States, California is where the plate boundary and most of the earthquakes are happening. Italy is the same thing in Europe. It's the most common source of earthquakes. The 2009 earthquake that killed several hundred people is on the same fault system. As was a quake back in 1997. There have been as many as 150 aftershocks. What are the big concerns right now? There Mr. Be continuing aftershocks. That mountain range is characterized by earthquake sequens, where there will be a lot of events. There will probably be more damaging earthquakes in the sequence, potentially larger than the first one. As they're searching for survivors, they're having to deal with significant aftershocks, yes? Absolutely. The recovery time can be very, very dangerous. The building's unstable. Any concern here at home? No, one thing we have seen when we look at how earthquakes trigger others, it happens very nearby. Once you get more than 100 miles away, you just don't see any extra triggering going on. It won't affect the rate here. We appreciate your expertise. Dr. Lucy Jones, thank you for joining us. Thank you for having me.
