Aftershocks are smaller earthquakes that occur after the main or larger one. Normally
after shocks are a sequence of minor earthquakes that can be composed of only few
or several hundred ones. Aftershocks can be repeated several times during minutes,
hours, weeks, months and even years after a main earthquake event.
Also known as magnitude is in how strong an earthquake was and it is normally referred
to the Richter scale.
Body waves are earthquake waves that travel in the interior of the earth, the most
important body waves are the P and S waves called in this manner because the way
they move, each one has a different effect on how they shake the ground.
Blind Thrust Fault
A blind thrust fault is a fault hidden under the surface of the earth, In other words
this rupture is not visible in the surface, therefore could be more dangerous than
the obviously visible faults because not always are properly detected and known.
Blind Thrust Faults (Hidden Fault From the Surface)
Is the deeper or innermost part of the earth, the outside diameter reach about 3000
miles below earth’s surface and it is primarily made of liquid metal mostly iron.
The central or inner core is made of solid metal also mostly made of iron.
Is the skin of the earth and has a thickness of about ten to more than 60 Km depending
of the world geographical location. In this upper layer is were most earthquakes
are produced due to it fragility
Epicenter Epicenter is the direct vertical location on the surface of the earth where
the earthquake focus occurred.
A=Earth diameter from poles =12,713 Km
B=Liquid core = 3059 Km
C=Inner Core = 804 Km
Is when two earth plates collide or when the earth crust is compressed at one point
by opposite forces
Is when the earth crust is pulled apart
Is when two earth plates are pulled on opposite directions
