3rd Biennial Workshop on Subduction Processes emphasizing the KurileKamchatka-Aleutian Arcs
Linkages among tectonism, magma genesis, and eruption in volcanic arcs
Geophysical Institute, University of Alaska, Fairbanks, Alaska
June 9th –15th 2002
SECOND CIRCULAR and CALL FOR ABSTRACTS
The Kurile-Kamchatka-Aleutian volcanic arcs are among the least understood in the world. Yet, their high level of
activity and continuity across continental and oceanic lithosphere provide an exceptional opportunity to understand
the linkages among tectonism, magma genesis, and eruption that characterize subduction zones. The scientific
promise is so great that obstacles of formidable distances and political divisions must now be overcome. This
continuing series of meetings seeks to build a vital international geoscience community in the North Pacific, while at
the same time drawing upon insights from workers in other areas. A special emphasis of the forthcoming meeting
will be to report progress on understanding the Aleutian Arc. This understanding has advanced greatly in recent
years as a result of the rapid growth in monitoring and related research by the Alaska Volcano Observatory, as well
as by other efforts. Field trips will be held before, during, and after the meeting. The intent is to nurture productive
collaborations in monitoring of and research into magma-genic subduction zone processes, both between
geoscientists in Alaska and in the remainder of the United States, and between those of the US and its North Pacific
neighbors.
ABSTRACT DEADLINE APRIL 19th 2002
Abstracts are limited to two pages with figures and references. Please format with a minimum of
2.5 cm margin on all sides, and a minimum font size of 12 points. Submit abstracts
electronically to Jon Dehn (jdehn@gi.alaska.edu). Any common format is acceptable--simple text,
Microsoft Word, Acrobat PDF, with figures as GIF, TIFF, or EPS files. For help with
abstract submittal, please contact the local organizing committee. Please include the attached
registration form and payment. Be sure to specify the excursion and short course preference.
Steering Committee:
Boris Ivanov and Evgenii Gordeev, Petropavlovsk-Kamchatsky, Russia
Minoru Kasahara and Mitsuhiro Nakagawa, Sapporo, Japan
Jonathan Lees, Chapel Hill, NC, and John Eichelberger (chair), Fairbanks, AK, USA
Local Organizing Committee:
Jim Beget, Brandon Browne, Jon Dehn, John Eichelberger (chair), Jeff Freymueller, Jim Gardner, Pavel Izbekov,
Jessica Larsen, Steve McNutt, Tom Miller, Seth Moran, Tina Neal, Richard Waitt
Form of Workshop:
In order to strengthen exchange, all sessions will be interdisciplinary. Invited speakers will begin workshop sessions
with oral presentations designed to bring everyone “up to speed” on major issues concerning this diverse and
dynamic setting. Each session will concentrate on an over-arching theme that will benefit from interdisciplinary and
international discussion. Submitted works will be presented as posters, which will be displayed throughout the
week, giving all participants time to exchange ideas. An abstracts volume will be distributed among participants,
and abstracts will be made publicly available via a web site. A report of the meeting will be published in Eos and
other appropriate locations.
Sponsorship:
The meeting is sponsored by the UAF Geophysical Institute, the Volcano Hazards Program of the US Geological
Survey, the US National Science Foundation, and by the International Association for Volcanology and Chemistry
of Earth’s Interior (IAVCEI) and The International Arctic Research Center (IARC). These funds are being used to
support the attendance of scientists and students from Russia, Japan, the Lower 48 States, and under- developed
countries.
Meeting Venue:
Geophysical Institute, University of Alaska Fairbanks
Transportation:
Fairbanks is served by Alaska and Northwest Airlines. In addition, Delta, United, American, and Magadan Air fly
into Anchorage. Participants wishing to attend the meeting only should book a round trip to Fairbanks. Those who
wish to participate in pre- or post-meeting excursions will need to arrange for a stop Anchorage. (One can also rent
a car and drive from Anchorage to Fairbanks, but this requires about 8 hours.)
Weather:
June in Fairbanks is generally sunny (~22 hours of sunlight per day), with occasional light rain, and temperatures of
20+/-10oC. Field trips will encounter cooler and much wetter and windier conditions. Trip leaders will provide
instructions as to necessary field gear.
Costs:
We anticipate that costs for food and lodging will average about $100/day. There will also be a registration fee of
$300 for professionals and $100 for students to cover group events and transportation. Field trips fees are listed
above. The Fairbanks area trip is included in the registration fee.
Financial support:
The organizers expect to be able to provide a limited amount of financial assistance to those who need support to
participate in the meeting. Participants needing support should so indicate on their registration form.
If you are interested in receiving subsequent circulars concerning this meeting, please return the attached file and
your abstract to Jon Dehn (jdehn@gi.alaska.edu). Few field trips have been conducted in Alaska volcanic areas in
the past, so it is difficult for us to gauge what the level of interest will be. We may find it desirable to modify the
agenda to reflect responses to this announcement.

1964, 1976, 1986. Tephra, pyroclastic flows, dome growth, repeated
landslide/debris avalanche. One of the most active volcanoes in Alaska,
and the longest and most intensively monitored (seismic and real-time
geodetic). Topics for discussion; ezplosive vs. effusive behavior, reposeeruption cycles, eruption triggerin, magma-mixing, behavior and
emplacement of debris avalanches, volcanogenic tsunamis, monitoring

Katmai I: in Katmai National Park on the Alaska Peninsula; Products of the great 1912 eruption- Valley of Ten
Thousand Smokes ignimbrite sheet, Novarupta Dome and 1912 vent
structures, Katmai Caldera formed by collapse in 1912; Southwest
Trident Volcano- lava flows and cone formed during 1950s and 60s; first

followed by day hikes from huts, last night at lodge; Leader: John
Eichelberger, UAF; very strenuous. Topics: Relationships among
associated but chemical distinct magmas, origin of high-silica rhyolite,
magma storage (seismic and petrologic constraints), caldera formation,
pyroclastic flows, plinian eruptions, effusive eruptions, magma mixing.

Maximum of 7 participants. Field trip fee does not include meals at
lodge and air tour (~$300).
The trip will leave from Anchorage on Sunday, June 16, and also end
in Anchorage.
Pre-workshop short course:
1. Remote Sensing Short Course: This short course is design for those interested in using the remote sensing data
acquired by AVO for real time monitoring. AVO is perhaps unique
among volcano observatories in its heavy reliance on remote sensing
data for generating eruption warnings. On the first day, there will be a
series of lectures to familiarize participants with satellite remote
sensing, the types of imagery available, and what volcanic processes
look like from space. Several examples from AVO's vast archive
spanning almost all eruption types will be used. Images will be
manipulated in a "hands-on" environment. The second day will show
participants how to get the imagery themselves (from UAF/GI sources
as well as publicly available imagery such as Landsat, MODIS,
ASTER, etc.), and how AVO monitoring operations function. They
will have the chance to take part in a monitoring session, and see how
the remote sensing alert system works. June 7-8, Fairbanks; Leaders: AVO Remote Sensing Group. Maximum 15
participants. (Fee does not include lodging in Fairbanks, 2 nights at ca. $70 each)
