What are
earthquakes?
An earthquake is the
result of a sudden
release of energy in the
Earth's crust that creates
seismic wave.
Where do they
occur most often?
Why?
The most recent earthquakes
occur in Alaska . The center is in
a molten state,
under tremendous temperature
and pressure. Moving
outwardly,
each layer becomes cooler and
more firm until the crustal layer
is reached. Although solid in
texture, the crust is fractured
into
unknown numbers of cracks,
faults and fissures throughout
the
world. A fault is considered
active if slow creep or periodic
movement occurs. This constant
movement is the result of
energy forces swirling deep
within the earth.
How likely is it
Anderson , Indiana
will experience an
earthquake?
Although earthquakes are not a
regular occurrence in our area
it is believed a strong
earthquake could soon hit our
region
What are the effects
