Why would a similar earthquake in Los Angeles be less destructive than in Sichuan?

The destruction caused by an earthquake is largely determined by the type of soil and rock that the earthquake occurs in. In Los Angeles, the soil and rock are much more stable than in Sichuan, which is located in a seismically active region. This means that the shaking from an earthquake in Los Angeles would be less intense and less likely to cause damage than an earthquake in Sichuan. Additionally, Los Angeles has stricter building codes and more earthquake-resistant structures, which would help to reduce the destruction caused by an earthquake.
