英语听力：自然百科 真实的庞贝—9

The melting rock is forcing its way out. In fact, its effects are felt years before. The city lives through something which today would be seen as a terrible warning.  

 

This is evidence of a major disaster, an earthquake that hit the city in 62 A. D., just 17 years before the final eruption¹. What we find is that, in this wall for example, that we have the brick in the corner which surrounds this nice diamond shaped wall. In fact, it's broken off at this point, and is instead replaced by a much more poorly built wall. And so the walls have been rebuilt with that rubble² into this much more basic design. 

 

Even though the people on Pompeii didn't know, it is clear to volcanologist  today that this earthquake of 62 B.C.(A.D.?) was a precursor³ of the eruption. It indicates that the magma is about to reach the surface. And a new eruption is about to occur.

 

Pompeiians definitely didn't understand the dangerous position they were in. They even built the city on a offshoot of the previous lava⁴ flat.
