This
presentation
uses
data
from
several
eruptive
episodes
of
Mount
St.
Helens
in
the
1980's
to
show
the
way
in
which
a
series
of
eruptions
were
accurately
predicted
by
USGS
scientists
as
far
as
3
weeks
before
eruptive
activity
occurred.
Several
modules
demonstrate
the
use
of
earthquakes
and
deformation
of
a
volcano
for
predicting
eruptions
and
allow
you
to
predict
an
actual
eruption
of
Mount
St.

This
resource
provides
general
information
about
volcanoes.
It
illustrates
the
growth
of
a
volcano,
using
Paricutin
and
Mt.
St.
Helens
as
examples
of
an
active
volcano
and
a
lava
dome.
The
terms
extinct
and
dormant
are
also
discussed.
This
site
provides
an
explanation
of
why
and
how
volcanoes
form,
zones
of
subduction,
mid-ocean
ridges,
and
hot
spots.
Deadly
dangers
associated
with
eruptions
are
discussed

In
spite
of
the
unpredictability
of
volcanoes,
scientists
have
learned
to
read
the
many
signs
they
display
prior
to
an
eruption,
in
the
hope
of
minimizing
damage
to
lives
and
personal
property.
This
video
segment
describes
efforts
of
scientists
at
the
Pinatubo
Volcanic
Observatory
to
read
the
signs
presented
by
Mount
Pinatubo,
just
before
it
unleashed
one
of
the
most
powerful
eruptions
of
the
20th

This
volcanoes
site
provides
information
about
volcanoes
as
well
as
a
classroom
activity.
There
are
video
clips
which
show
some
of
the
features
discussed,
such
as
types
of
lava
and
eruptive
styles.
Topics
covered
by
the
text
include
how
rocks
melt,
where
and
why
volcanoes
occur
(plate
tectonics),
hot
spots,
volcanic
hazards,
forecasting
eruptions
and
coping
with
risk.

in
the
U.S.,
the
role
of
the

In
this
lesson,
students
investigate
the
processes
that
build
volcanoes,
the
types
of
rocks
they
create,
the
factors
that
influence
different
eruption
types,
and
the
threats
volcanoes
pose
to
their
surrounding
environments.
They
will
also
create
a
notebook
of
volcano
characteristics
and
use
what
they
have
learned
to
identify
physical
features
and
eruption
types
in
