Our transcription: And yet hospitals, schools, and highways have been built in the vicinity of dangerous faults.
Clearly, the prospect of tearing these structures down and relocating the millions of people who utilize them is not feasible.
The most practical alternative seems to be retrofitting existing structures, so that they will be more likely to survive a major earthquake.
Most casualties associated with earthquakes are caused not by the quakes themselves, but by the failure of buildings, bridges, and other structures.
This is one of the most serious problems of the government, what to do with buildings or with structures that we know that are built on soil that will suffer damage.
At the moment anything that we will do there will be very expensive.
It's a very expensive operation.
It can be done; however, it will require a tremendous economic effort.
