Natural
hazards
such
as
earthquakes,
tsunamis,
and
volcanoes
affect
both
coastal
and
inland
areas.
Long-term
data
from
these
events,
including
photographs,
can
be
used
to
establish
the
past
record
of
natural
hazard
event
occurrences.
These
data
are
also
important
for
planning,
response,
and
mitigation
of
future
events.
The
National
Geophysical
Data
Center
plays
a
major
role
in
post-event
data
collection.

This
site
introduces
the
several
methods
geologists
use
to
monitor
changes
in
a
volcano.
These
methods
assist
in
forecasting
intrusions
and
eruptions
and
consist
of
ground
movements,
seismicity,
gas
geochemistry,
and
geology.
As
a
result
of
this
lesson,
students
will
realize
that
eruptions
have
precursor
activities,
recognize
patterns
in
volcano
behavior,
and
interpret
graphical
data.
This

The glossary has about 60 terms that are primarily types of volcanoes or vents, eruption types, and eruptive products. Clicking on a term displays a captioned photograph illustrating the concept and a glossary definition. Below the photgraph are related glossary terms and sometimes other information or photograph links.

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.

covers
the
progress
of
the
early
1960
Kapoho
eruption
of
Kilauea
Volcano,
Hawaii,
and
the
damage
it
caused.
The
eruption
caused
havoc
in

rural
paradise
until
the
lava
fountains
and

In
1986
the
eruption
of
Kilauea
Volcano
changed
from
the
episodic
fountaining
of
lava
and
gas
at
Pu`u
O`o
cone
every
few
weeks
to
the
continuous
outpouring
of
lava
from
a
new
vent
only
3
kilometers
away.
The
volcano
began
releasing
a
large,
steady
supply
of
sulfur
dioxide
gas
into
the
atmosphere.
During
the
episodic

enough

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

provides
an
explanation
of
why
and
how
volcanoes
form,
zones
of
subduction,
