Earthquake Destruction | National Geographic

when we least expected when release
prepared disaster can strike and few
disasters are as unsettling as an
earthquake
my guess is that earthquakes are really
so scary because you don’t have any
warning it’s the only thing besides a
nuclear war that can really one second
you’re living in a big beautiful city in
ten seconds later it’s flat every day
the earth is shaken by hundreds of small
earthquakes most go unnoticed they
usually occur along the boundaries of
the thin plates that cover the earth
like an eggshell driven by the heat deep
within the Earth’s core the plates grind
against each other on long lines called
faults when the plates find their motion
blocked stress builds up finally the
fault gives way
the released energy races through the
earth in the form of seismic waves for
much of the world the movement of plates
like these is also an indispensable
creative force we didn’t have
earthquakes if we didn’t have this great
flow of heat from the interior of the
earth the earth would be a cold dead
place if it wasn’t for this great flow
of heat
there’d be no continents no oceans no
atmospheres the earth would be as dead
and dry and cold as the moon it’s really
the earthquakes that create the
topography the valleys the mountains
earthquakes have been shaping landscapes
for eons it’s only in the last few
hundred years that civilization has
gotten in the way and when it does
this is just an excerpt from nature’s
fury
