This is the inner core of the earth.

它就是地球的内核。

And it's all driven by the core of the earth machine.

其动力就来源于地球机器的核心。

This earthquake was shallow that means the effects are going to be felt much more severely than if it were much further down into the core of the earth.

这次地震的震源较浅，意味着地震造成的影响要比深入地核造成的影响严重得多。
