Radially, that is in every direction.
Seismic Waves
Seismic waves are the forms of energy produced by an earthquake.
The point of origin of seismic waves during an earthquake is called the "focus" or "hypocenter." This is the location within the Earth where the seismic energy is released. The point directly above the focus on the Earth's surface is known as the "epicenter."
Seismic waves move in all directions away from the point of earthquake origin, traveling through the Earth's interior in a wave-like pattern. The waves can be categorized as body waves (P-waves and S-waves) that travel through the Earth's interior and surface waves that travel along the Earth's surface.
The underground point of origin of an earthquake is called the hypocenter or focus. At this point, the seismic waves are first generated and then spread out in all directions, causing the shaking felt on the surface.

Seismic wave is mostly referred to earthquake impact ,so the word epicentre can be applied to its origin or point of impact.
This idea was derived from the behavior of seismic waves as they travel through the Earth. Their direction and speed from their point of origin indicate a molten outer core and a solid inner core.
The point of origin of an Earthquake within the earth is known as the hypocentre. It can also be called the focus.Directly above this on the surface is the earthquake's epicenter.
Depends on your point of origin.
If there is a congestion in one direction, the FECN (forward explicit congestion notification) bit is set to inform routers in the forward direction (from the point of view of the traffic) about the congestion. Also, eventually some frames will travel back to the origin; in that case, the BECN (backword explicit congestion notification) bit is also set to inform the origin about the congestion.
They propagate spherically outwards from their point of origin, except in unusually cases, such as the laser, when the light is contained within a column and disperses very gradually.
