好像这次都是记录的高限了，而且是几百年才有的一次。
所以，下次比这次厉害的几率应该小点了。

Does a small earthquake mean that a larger earthquake is coming?
No, except for very rare exceptions. Every year, hundreds of earthquakes occur in Canada. Only a very tiny minority of these precede a larger earthquake.
Although a large earthquake may be preceded by a foreshock (the Saguenay earthquake of November 1988 is an example), the occurrence of a small earthquake is not in itself a typical sign. Hundreds of small earthquakes occur every year in Canada, whereas major earthquakes have occurred only a few times in this century.
A small earthquake, however, provides an ideal opportunity to offer reminders about safety measures to take before, during and after an earthquake.
