When measuring the epicentral distance of an earthquake with a small epicentral distance, first measure the reading of the initial motion of P wave, and then confirm the arrival of S wave. [Notes 3] The value of the epicenter distance Δ is found on the travel timetable according to the arrival time difference between the P wave and S wave. [4]
During an earthquake, seismic waves propagates in all directions from the hypocenter. Seismic shadowing occurs on the opposite side of the Earth from the earthquake epicenter because the planet's liquid outer core refracts the longitudinal or compressional while it absorbs the transverse or shear waves . Outside the seismic shadow zone, both ...

The earthquake will be strongest at its epicenter, the point on the surface directly above where the quake started, and the effects will be diminished as they spread further.
Thurston's earthquake theorem states that for any two points x, y of a Teichmüller space there is a unique left earthquake from x to y.It was proved by William Thurston in a course in Princeton in 1976–1977, but at the time he did not publish it, and the first published statement and proof was given by Kerckhoff (1983), who used it to solve the Nielsen realization problem.
“Drop, Cover, Hold on. Protect yourself,” the U.S. Geological Survey warned moment before the eathquake struck.
The moment tensor solution is displayed graphically using a so-called beachball diagram. The pattern of energy radiated during an earthquake with a single direction of motion on a single fault plane may be modelled as a double couple, which is described mathematically as a special case of a second order tensor (similar to those for stress and strain) known as the moment tensor.
Roadways closest to the epicenter were full of people driving away from the coast. Tsunamis can occur when an underwater earthquake rapidly displaces massive amounts of water, leading to a large ...
