ep·i·cen·ter

 (ĕp′ĭ-sĕn′tər)
n.
1. The point on the earth's surface directly above the focus of an earthquake.
2. The focal point of a usually harmful or unpleasant phenomenon or event; the center: stood at the epicenter of the international crisis.

ep′i·cen′tral adj.
Usage Note: Epicenter is properly a geological term identifying the point of the earth's surface directly above the focus of an earthquake. No doubt this is why the Usage Panel approves of figurative extensions of its use in dangerous, destructive, or negative contexts. In our 2008 survey, 74 percent accepted the sentence identifying a country as the epicenter for terrorist financing. The Panel is less fond but still accepting of epicenter when it is used to refer to the focal point of neutral or positive events. Fifty percent approved of the word in a sentence identifying New York City as the epicenter of European immigration. These percentages are both down a little from those in our 1996 survey, but not significantly.
