Resources Laboratory -
- The Air Resources Laboratory, conducts research on processes
that relate to air quality and climate, concentrating on the
transport, dispersion, transformation, and removal of trace
gases and aerosols, their climatic and ecological influences,
and exchange between the atmosphere and biological and non-biological
surfaces. The time frame of interest ranges from minutes and
hours to that of the global climate. Research in all of these
areas involves physical and numerical studies, leading to the
development of air quality simulation models. ARL provides scientific
and technical advice to elements of NOAA and other Government
agencies on atmospheric science, environmental problems, emergency
assistance, and climate change.
- The Alaska Volcano Observatory (AVO) is a joint program of
the United States Geological Survey (USGS), the Geophysical
Institute of the University of Alaska Fairbanks (UAFGI), and
the State of Alaska Division of Geological and Geophysical Surveys
(ADGGS). AVO was formed in 1988, and uses federal, state, and
university resources to monitor and study Alaska's hazardous
volcanoes, to predict and record eruptive activity, and to mitigate
volcanic hazards to life and property.
- Alaska contains more than 40 active volcanoes, many of which
have erupted violently and repeatedly over the past 200 years.
Alaska also boasts the largest eruption on the planet in the
last 100 years: the Katmai eruption of 1912 which formed the
famous Valley of Ten Thousand Smokes, now part of Katmai National
Park and Preserve.
Volcanic Past -
- Though few people in the United States may actually experience
an erupting volcano, the evidence for earlier volcanism is preserved
in many rocks of North America. Features seen in volcanic rocks
only hours old are also present in ancient volcanic rocks, both
at the surface and buried beneath younger deposits. A thick
ash deposit sandwiched between layer of sandstone in Nebraska,
the massive granite peaks of the Sierra Nevada mountain range,
and a variety of volcanic layers found in eastern Maine are
but a few of the striking clues of past volcanism. With this
perspective, an erupting volcano is not only an exciting and
awesome spectacle in its own right but a window into a natural
process that has happened over and over again throughout Earth's
history. -- From: Brantley, 1994

on active volcanoes. From here you can find many types of materials
on active volcanoes worldwide, such as maps, photographs and
full texts of dissertations and a few elusive documents. The
Electronic Volcano will guide you to resources in libraries
or resources on other information servers.

to folks, not only in improving agriculture or as an energy
source, but also economically in business opportunities and
recreation and tourism ... includes Fertile Soils, Geothermal

St. Helens National Monument Hiking -
- Courtesy of the Blue Heron Inn. There are many trails on the
east side of Mount St. Helens, leading hikers into the heart
of the blast area. They provide outstanding views of the new
lava dome. The south side of Mount St. Helens provides outstanding
opportunities to discover the ancient lava flows and recent
mudflows that scoured down the slopes of Mount St. Helens. Trails
on the west side of Mount St. Helens are few but what is lacking
in number is made up with unparalleled views of this volcanic
landscape. Trails, campgrounds, and old growth forests can all
be found just north of the National Volcanic Monument in the
Randle Ranger District. These areas relatively unaffected by
the volcano offer a sharp contrast to the blast area just a
few miles to the south. And there are a number of trails which
skirt the perimeter of the Mount St. Helens Volcano. A climbing
permit is required for these trails. To ensure a quality hiking
experience and your safety, wear sturdy shoes, bring sunscreen,
and carry one quart or more of water per person.
St. Helens -
- The morning of May 18, 1980 my sister came into my home excitedly
telling me that the mountain was exploding. Well, I didn't want
to miss that so I drove to the top of the hill where I could
see that she was right. I went back to the house, grabbed my
camera, jumped into my car and sped to the Kelso airport. I
quickly got into my Cessna 172 plane with three friends that
were standing by and headed for Mt.St. Helens ......

Geological Survey -
- Created by an act of Congress in 1879, the USGS has evolved
over the ensuing 120 years, matching its talent and knowledge
to the progress of science and technology. Today, the USGS stands
as the sole science agency for the Department of the Interior.
It is sought out by thousands of partners and customers for
its natural science expertise and its vast earth and biological
data holdings. The USGS is the science provider of choice in
accessing the information and understanding to help resolve
complex natural resource problems across the Nation and around

- Volcanoes destroy and volcanoes create. The catastrophic eruption
of Mount St. Helens on May 18, 1980, made clear the awesome
destructive power of a volcano. Yet, over a time span longer
than human memory and record, volcanoes have played a key role
in forming and modifying the planet upon which we live.

of Canada -
- Canada has examples of almost every type of volcano. Although
none are erupting now, at least 3 did in the last few hundred
years and numerous others have the potential to erupt in the
near future. Other countries volcanoes also can affect Canadians:
eruptions in Alaska or along the west coast of the U.S.A. can
impact agriculture and air travel across western Canada. Mt.
Baker in particular has the potential to affect the Fraser Valley.
In addition, large-magnitude eruptions anywhere in the world
may affect our weather.
- FEMA for Kids -
- A volcano is a mountain that opens downward to a pool of molten
rock below the surface of the earth. When pressure builds up,
eruptions occur. Gases and rock shoot up through the opening
and spill over or fill the air with lava fragments. Eruptions
can cause lateral blasts, lava flows, hot ash flows, mudslides,
avalanches, falling ash and floods. Volcano eruptions have been
known to knock down entire forests. An erupting volcano can
trigger tsunamis, flashfloods, earthquakes, mudflows and rockfalls.
of Guatemala -

There are hundreds of ancient volcanic vents and sites of past
volcanic activity in Guatemala but only some 35 of these are
officially recognized as "volcanoes."
