“The point on the fault plane where the earthquake rupture is initiated is called the focus or hypocentre.”

“The starting point of an earthquake under ground is called the hypocentre or focus.”

“Displacement at the hypocentre of the earthquake must be sufficiently large to propagate to the surface.”

“Only two small communities are located within miles of the hypocenter.”

“Magnitude is a measure of the energy released by a quake at its hypocenter, the point underground where movement first occurs along a fault.”

“The degree of damage depends upon the distance from the center of the bomb blast, which is called the hypocenter or ground zero.”
