Why didn't the 7.8 Wenchuan Earthquake Meteorological Bureau report it and deliberately concealed it? Or did you not predict it at all?

Earthquake prediction is a worldwide problem. Due to frequent pre-earthquakes before major earthquakes, only a few earthquakes can be taken seriously.

Earthquakes are difficult to predict. Generally, we can only predict where the earthquake will happen in the future, and the specific time of the earthquake cannot be predicted.

First: earthquakes are impossible to predict, and the sources are all hundreds of kilometers underground. Excuse me, can human science and technology and earthquake research equipment go deep into the ground for dozens or even hundreds of kilometers?

Second, the factors that cause earthquakes are very complicated, much more complicated than the formation of typhoons and clouds and rain. And the source is deep and unpredictable. Even the weather forecast is sometimes inaccurate, not to mention the earthquake.
