Earthquake is the shaking and
trembling that results from the
sudden movement of part of the
Earth’s crust.
A Volcano is a place in the Earth’s
surface through which molten rock
and other materials reach the
surface.
A Tsunamis is produce by a
earthquake. It is a giant sea wave.
It can travel at speeds of 700 to 800
kilometers per hour.
Primary Waves
Primary Waves are produced by
Earthquakes.
P-Waves are a type of elastic wave, also
called a seismic waves.
P-waves are recorded by seismometers
Secondary Waves
The S-Wave, secondary wave, or shear
wave is one of the main types of elastic
body waves.
The S-wave moves as a shear or
transverse wave.
Surface Waves
In physics, surface wave can refer to a
mechanical wave that propagates along
the interface between differing media,
usually two fluids with different
densities.
Cinder Cones
A Cinder Cone or Scoria Cone is a steep
conical hill if volcanic fragments that
accumulate around and downwind from
a volcanic vent.
Shield Volcanoes
A Shield Volcano is a large volcano with
shallow sloping sides.
The name derives from a translation of
“Skjaldbeiour” an Icelandic shield
volcano whose name means “broad
Shield,” from its resemblance to a
warrior’s shield.
Composite Volcanoes
Composite Volcanoes also called strato
volcanoes are formed by alternating
layers of lava and rock fragments. This
is the reason they are and composite.
