This is caused by the density variations in the earth which cause the velocity of seismic waves to change as they move between them which in turn causes refraction of the waves.
Further to this, the earth's outer core is a liquid which prevents seismic S-waves from travelling through it. This leads to a zone on the opposite side of the earth from an earthquake where S-waves are not detected.
depends on the focus and epicenter depends on the focus and epicenter
Earthquakes happen everyday everywhere so yes thialand often has earth quakes.
refraction
Divergent plate boundaries.
The shadow zone
Spreading center earthquakes are always shallow, subduction zone earthquakes can be very deep.Spreading center earthquakes are typically of lower magnitude than subduction zone earthquakes.
The shadow zone, located at a distance of 103 to 143 degrees from the earthquake epicenter, is the area on Earth's surface where both P and S waves are completely absorbed and do not arrive due to the core's properties.
In shadow zone, seismograph does not record signals. For P-wave it is b/w 104-145 degress.These earthquake waves exhibit same properties as other waves like reflection, refraction etc.As core has denser matter so P-waves will bend inward and hences they will form a shadow zone. S-waves don't pass through liquid phase, core. So, shadow zone is larger here.
the shadow zone is a result of the core stopping
An active zone is where earthquakes happen and inactive is where they don't.
a place were earthquakes are found
no, an s-wave shadow zone is way larger
depends on the focus and epicenter depends on the focus and epicenter
i finished the game, and never once did i ever come across anything called a shadow zone
S waves do not pass through Earth's liquid outer core, which causes a shadow zone on the opposite side of the Earth from an earthquake. The liquid outer core absorbs and blocks S waves, preventing them from reaching the surface beyond the shadow zone.
It depends on where the earthquake occurs.
There no way.
