Why didn't the country have any foresight before the Wenchuan earthquake? Is the earthquake really so unpredictable?

what do you think? Haven't science developed to the stage of prediction? I think not.

First of all, if the Wenchuan earthquake is predicted by the state, once it is announced, tens of millions of people in Sichuan will cause panic, many institutions will avoid paralysis in advance, many traffic will be in chaos, and even some lawless people will take advantage of the fire to rob. Form a huge social unrest.
