How it's used
Distinguish this clearly from 震央, which refers to the point on the surface directly above the hypocenter. While 震源 is the actual location of the rupture deep underground, 震央 is the term most commonly cited in news reports and public warnings because it is easier to map geographically.

Common mistake
Learners often confuse 震源 with 震央, using them interchangeably when describing the location of an earthquake. Remember that 震源 is the deep source, whereas 震央 is the surface projection.
