SOLAR SYSTEM

Detailed explanation-1: -The focus is the place inside Earth’s crust where an earthquake originates. The point on the Earth’s surface directly above the focus is the epicenter. When energy is released at the focus, seismic waves travel outward from that point in all directions.

Detailed explanation-2: -The point where an earthquake originates is called the seismic focus. It is also known as hypocenter.

Detailed explanation-3: -The deepest earthquakes occur within the core of subducting slabs-oceanic plates that descend into the Earth’s mantle from convergent plate boundaries, where a dense oceanic plate collides with a less dense continental plate and the former sinks beneath the latter.
