Earthquake prediction is not highly reliable, but geologists do know

choose one:
a) more earthquakes happen along plate boundaries than happen at intraplate locations.
b) that recurrence intervals can provide accurate short-term predictions.
c) that earthquakes never happen outside of seismic belts.
d) that in the long term, earthquakes happen at predictably spaced time intervals.

They do know it is more likely to happen along plate boundaries.

Geologist hardly predict but they can record Earthquake through the instruments called seismographs which works by been sets firmly in the ground with a heavy weight hanging free on it.

In conclusion, they believed earthquakes are more likely to happen along the plate boundaries than happen at intraplate locations.
