give me an example of epicenter

One example of an epicenter is the location of a major earthquake.

For instance, the epicenter of the devastating 2011 Tohoku earthquake in Japan was offshore, near the east coast of Honshu Island. The epicenter was identified to be approximately 70 kilometers east of the Oshika Peninsula, in the Pacific Ocean. This earthquake, with a magnitude of 9.0, caused widespread destruction, triggered a tsunami, and resulted in the loss of thousands of lives.
