Epicenter - Shinou (English spelling)

Japanese: 震央 - しんおう（英語表記）epicenter

The point on the Earth directly above the underground epicenter where the earthquake occurred. It is indicated by latitude and longitude. The epicenter reported in newspapers is the epicenter. The distance from the epicenter to the observation point is called the epicentral distance, and if the epicenter distance is calculated, the epicentral distance can also be determined. In addition to being expressed in kilometers, the epicentral distance can also be expressed as the size of the angle between the epicenter and the observation point as viewed from the center of the Earth.

地震が発生した地下の震源の真上にあたる地球上の地点。緯度，経度で示される。新聞などに発表される震源とは震央のことである。震央から観測点までの距離を震央距離といい，震源距離が求められれば，震央距離もわかる。震央距離は km単位のほか，地球の中心から見た震央と観測点の 2点間の角度の大きさで表すこともある。
