Have you been in Epicenter?

I haven't. Epicenter is a commonly misused word...

It seems that we use it when we want to express being in the center of some event, happening, or some mass gathering…

But epicenter does not mean the center. It is the projection from the center to the earth’s surface. Often used in seismology, the term would describe the point, which is the shortest distance from the hypocenter (or focus) to the point on the surface. So it is more like being above, not in the midst of something, and this is not the meaning people imply when using the word.

Here is how it is defined in the WikiPedia

"The epicenter, epicentre /ˈɛpɪsɛntər/ or epicentrum[1] is the point on the Earth's surface that is directly above the hypocenter or focus, the point where an earthquake or underground explosion originates."

So, when you read in the newspaper that the journalist was in the epicenter of the event, don't trust the guy or the gal. They sure weren't :)
