seismic waves - Coggle Diagram
seismic waves
Seismic
stress relief
tension builds up
releasing energy in the form of seismic waves
exceeds the strength of the material
se produce un fallo repentinoa sudden failure occurs
epicenter and hypocenter
hipocentro
is the point within the Earth where the failure occurs
epicenter
is the point on the surface directly above the hypocenter
the intensity of the earthquake decreases
as the seismic waves move away from the epicenter
tectonic plates
types of limits
converging limits
plates are approaching and may collide
under the other
subducción
creating
mountains
oceanic fosas
which may cause a plate to shift
deviating limits
separate
magma rises
form a new cortex
as in the oceanic ridges
transforming limits
slide laterally
side by side
movement
move at an average speed
a little centimeters for years
can acumulate a big tension
in the borders of the plates
Tsunami
vertical ground displacement
Tsunami Waves
generate waves
very bigs
can travel at high speed
in the ocean
as it approaches the coast
are more slower
the size aument
occurs under the ocean
in convergent limits
vertical displacement
can cause a large displacement of water
