This
online
simulator
lets
students
observe
what
happens
to
volcanic
eruptions
as
the
silica
content
of
the
magma
changes.
Operating
a
slider
changes
the
percentage
of
silica,
and
the
display
shows
the
rock
type,
type
of
eruption,
and
type
of
volcanic
edifice.
It
also
displays
temperature,
pressure,
viscosity
of
the
lava,
and
seismic
activity.
A
brief
tutorial
describes
how
to
use
the
simulator

This

is
an
active
simulation
of
an
explosive
volcanic
eruption.
The
model
volcano
is
a
plastic
35
mm
film
cannister
that
erupts
(the
lid
blows
off)
when
gas
pressure
generated
by
dissolving
alka
seltzer
is
sufficiently
high.
It
is
realistic
in
that
the
timing
of
the
eruption
is
difficult
to
predict
precisely
and
in
that
the
eruption
occurs

Major
volcanic
eruptions
alter
the
Earth's
radiative
balance,
as
volcanic
ash
and
gas
clouds
absorb
terrestrial
radiation
and
scatter
a
significant
amount
of
the
incoming
solar
radiation,
an
effect
known
as
"radiative
forcing"
that
can
last
from
two
to
three
years
following
a
volcanic
eruption.
This
results
in
reduced
temperatures
in
the
troposphere,
and
changes
in
atmospheric
circulation
patterns.

Eruption!
is

people
and
as
much
property
as
possible
in
spite
of
the
threat
from
the
volcano.
