Question

3. Smaller quakes that happen after a big earthquake has
occurred​

Answer 1

Answer:

Aftershocks are smaller earthquakes that occur in the same general area during the days to years following a larger event or “mainshock”.

Answer 2

Explanation:

Fault lines or different portions of the same fault can be classified as locked or creeping. Creeping faults shift slowly over time, and may undergo smaller quakes like the ones observed this week. Locked faults, however, don't move, causing pressure to build until a large-magnitude earthquake releases it.
