You need at least 3. seismic stations provide only a circle around the station. so from geometry 3 circles intersect in a point. that is why you need 3 stations
Oceanic water have latent heat or special heat capacity.
Explanation:
As oceans cover nearly 71% of the earth's surface and help in regulating the climate and weather patterns around places. They have specific heat and contain salt contents.
They trap and absorb the carbon dioxide and thus are called carbon sinks. They take up a large amount of solar energy and heat slowly as compared to the land surfaces.
