Answer:
The epicenter to a biologically impaired person is simply, the point where the devastation is much. The point where the earthquake originates.
Explanation:
I will further explain thus, between California and Los Angeles is about 50 miles apart. That is about 190 towns in between. So, whatever devastation we feel hear, will be triple what they will feel at the epicenter. Epicenter is where the damages to structures and environment are most.
I can go further to use what happens bomb exploxion to further drive home the meaning. If there is a bomb {grenade} explosion, the point where the explosion occurs has more devastation than areas about 100 meters away.
