Seismic Wave Transmission

1956
When an earthquake occurs, energy, which may reach the order of 1025 ergs in the greatest earthquakes is released, within a few seconds or less, from a focal region inside the Earth whose linear dimensions may be of the order of several kilometres. The (somewhat indefinite) centre of the focal region is called the focus.

Seismic waves and seismic barriers

Acoustical Physics, 2011
The basic idea of seismic barrier is to protect an area occupied by a building or a group of buildings from seismic waves. Depending on nature of seismic waves that are most probable in a specific region, different kinds of seismic barriers are suggested.
