这是因为地震级数是按对数计算的。
That's because quake magnitudes are calculated on a logarithmic scale.
地震级数是如何测量的？
因此，第一次报道的地震级数通常基于很小一部分的数据。
As a result, the first magnitude reported is usually based on a small number of recordings.
但由于许多地震发生在偏远地区抑或地震级数很小，他们就未报道。
However, many go undetected because they hit remote areas or have very small magnitudes.
地震是如何被记录下来的？地震是如何测量的？地震级数是如何确定的？
How are earthquakes recorded? How are earthquakes measured? How is the magnitude of an earthquake determined?
即使地震级数和烈度远高于七级，此建筑也能够以一种有利的变形方式来抵抗。
Even if the magnitude and intensity of earthquake is far greater than that in level 7, the building is still able to deform in an advantageous way to resist the seismic activity.
