官方称地震过后约有200余次余震发生，其中大部分震级较低。
Officials said that about 200 aftershocks were registered after the fatal one, the majority of which were of low magnitude.
但余震震级大于主震，这实属罕见，虽然之前也听说过。
It is rare, though not unheard of, to have an earthquake followed by a larger aftershock.
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.
历史记录的最高震级只有7.2到7.3，所以我想他们已经尽力了。
In the historical record the maximum magnitude is only 7.2 or 7.3. I think they \ \ \ 're doing as much as they can.
