What does the term earthquake epicentre mean?
The tectonic plates placed deep inside earth's crust [range may vary, say 5-100km]. As such, epicentre is defined as the centre point of the tectonic activity projected on earth's surface. Thus the epicentre can also lie on the surface of Sea/ Ocean also. Ocean water remains only up to 10 to 12 km deep [maximum being Marina Trench]The tectonic activity lies much below !!The epicentre is the point on the earth's surface directly above the earthquake's focus or hypocentre (the point within the earth where the fault rupture or movement actually occurs).As such, the seismic waves produced by an earthquake radiate away from this point. This is similar to the way waves or ripples in a pond move outwards in concentric circles from the point where you throw a stone into the water.
How many seismographs must be used to locate the epicenter of an earthquake?
Three sizemographs are needed to accuratley locate the earthquake's epicentre, the way to work it out is you draw three radi from the siesmographs to where the earthquake roughly is then you draw circles from that, the point where the three circles overlap is the epicentre.

The red giant star Betelgeuse, in the shoulder of the constellation Orion, is one of the brightest stars in the winter sky. It has been known since antiquity. We really have no way of knowing "who was first" or "what year..." for things that happened over 3,000 years ago. Mostly, the records were lost, or destroyed, or for things THAT long ago, they were never "recorded" at all.
