what is Epicentre???

Answer:
the point on the earth’s surface where the effects of a sudden movement (earthquake) are felt most strongly
पृथ्वी का वह भाग जहाँ भूकंप का झटका सबसे अधिक महसूस किया जाता है; अधिकेंद्र
Answer:
The epicenter, epicentre /ˈɛpɪsɛntər/ or epicentrum[1] in seismology is the point on the Earth's surface directly above a hypocenter or focus, the point where an earthquake or an underground explosion originates.During an earthquake, seismic waves propagate in all directions from the hypocenter. Seismic shadowing occurs on the opposite side of the Earth from the earthquake epicenter because the planet's liquid outer core refracts the longitudinal or compressional (P-waves) while it absorbs the transverse or shear waves (S-waves). Outside the seismic shadow zone, both types of wave can be detected but, because of their different velocities and paths through the Earth, they arrive at different times. By measuring the time difference on any seismograph and the distance on a travel-time graph on which the P-wave and S-wave have the same separation, geologists can calculate the distance to the quake's epicenter. This distance is called the epicentral distance,
