"Besides it being the biggest strike-slip earthquake ever recorded, the aftershock is the second biggest as far as we can tell," said Sieh.

非走滑型地震情况则复杂得多,既有视应力很高的孤立型地震,也有视应力很低的多震型地震。
For non-strike-slip type earthquake, the situation is more complicated, and there are single-shock earthquake of high apparent stress, and also multiple-shock earthquake of low apparent stress.

本次4.9级地震作出的震源机制解显示为走滑型,与1969年主震的情况较为类似。
The focal mechanism of the M4.9 earthquake shows that it belongs to strike slip type that is similar to the M6.4 earthquake in 1969.
