The Japan-Kamchatka-Alaska portion of the Pacific Rim of Fire is amongst the most geologically active
regions on Earth. This region is home to the largest earthquakes, tsunamis, and volcanic eruptions inrecorded history. Yet, this is a place where human communities have lived for thousands of years,
demonstrating a remarkable resilience to geohazards and adverse climate conditions. This continuing
series of meetings seeks to build upon and continue a vital international geoscience community in the
North Pacific to understand nature of the subduction processes and to better mitigate the associatedhazards posed to our society. The intent of the meeting is to nurture productive international
collaboration in research and monitoring. We welcome scholars from all countries to come and present
results of recent and ongoing research projects and hazard monitoring efforts.

John Eichelberger, Pavel Izbekov, Fairbanks, Alaska, United States
Mitsuhiro Nakagawa, Hiroaki Takahashi, Sapporo, JapanEvgeny Gordeev, Petropavlovsk-Kamchatsky, Russia
Meeting Venue:
University of Alaska Fairbanks
Themes of scientific sessions: Structure and History of North Pacific Subduction Zones
 Volcanism and Volcanic Processes
 Earthquakes
 Tsunamis
 Recent Advances in Monitoring of Volcanic and Seismic Activity
 Human Aspects of Geohazards: Resilience and Resources
Optional field excursions to Katmai National Park, Cook Inlet Volcanoes, Augustine Volcano, and the Chena
Hot Springs Resort will be conducted during, and after the meeting, if there is sufficient interest.
Scientific sessions proposed by February 29, 2016:
Recent Advances in Observing North Pacific Subduction Zones. Great earthquakes are common at
subduction zones worldwide, and even smaller subduction zone earthquakes can pose significant
hazards. Large earthquakes also cause significant long-lasting effects, such as aftershock sequences
and postseismic deformation. This session will feature studies of earthquakes of all types within theJapan – Kamchatka/Kuril – Alaska region around the North Pacific., from all disciplines.
Structure, History and Dynamics of North Pacific Subduction Zones. The structure, history and dynamics
of subduction zones can be probed by many disciplines, including seismology, geodesy, geology, andnumerical modeling. New data and new studies in recent years have greatly expanded our knowledge
about several North Pacific subduction zones, and the EarthScope program in Alaska is supporting afurther explosion of data. This session is appropriate for observational and/or modeling studies of thestructure, geological history, tectonics and dynamics of subduction zones.
This list will be updated.

FIELD TRIPS AND EXCURSIONS
Participants should arrange for their travel to and from the workshop, including stops for the excursions
as needed. Normally a stopover in Anchorage should not increase the total cost of the ticket. For questions
and help arranging travel, please contact the local organizing committee, and visit the meeting website at
http://www.gps.alaska.edu/JKASP/. Please note that some field trips are subject to cancellation if there
are not enough participants, or the cost per participant may increase if fewer than expected sign up. We
will notify registrants promptly of any changes.
AUGUSTINE
Date:
May 22-29, 2016
Trip Leader: TBA
Participants:
7
Cost:$2300** The trip cost includes lodging in Anchorage for two nights (May 22 and May 27), transportation to the field, and all
lodging and food expenses during the trip.

Augustine Volcano is an andesite and dacite dome complex built on Jurassic sedimentary rocks of the
Naknek Formation that forms Augustine Island, a small (~100 km2) unpopulated island located within
Kamishak Bay on the west side of Lower Cook Inlet, 290 km southwest of Anchorage, Alaska and 120 km
southwest of Homer, Alaska. It lies along an active segment of the Aleutian arc. In historical time, it has
produced more eruptions than any other volcano in the Cook Inlet region, with 6 major eruptions in thepast ~125 years (1883, 1935, 1963–64, 1976, 1986, and 2006). Augustine is the most intensively
monitored (seismic and real-time geodetic) volcano in Alaska. Recent eruptions have begun with explosive
generation of tephra and pyroclastic-flow deposits followed by prolonged periods of dome growth andlava-flow extrusion. The 1883 and several prehistoric eruptions additionally produced catastrophic
volcanic landslides that entered the sea and generated tsunamis. Topics to be discussed include
Pyroclastic deposits of the 2006 eruption; Volcanic landslides and tsunami generation; Prehistoric (pre1883) versus historical magma petrogenesis; Eruption triggering and magma mixing.
Tentative Schedule:
May 22:
Participants arrive to Anchorage, stay overnight in UAA dormitory
May 23:Acquire food, visit AVO, drive to Homer, Alaska, and take a chartered floatplane flight to thewest side of Augustine Island.
May 24-27: Examine pyroclastic-flow deposits, landslide deposits, tephra fall deposits, lava flows, anddomes while hiking up to 25 km a day over uneven and steep terrain in highly variable andunpredictable weather conditions carrying 10–15 kg backpacks.
May 28:Take charted floatplane flight from Augustine to Homer, then drive to Anchorage, arriving inlate afternoon, stay overnight in UAA dormitory.
May 29:Participants fly to Fairbanks.
Special Considerations:This field trip will require tent camping on a remote volcanic island and strenuous hiking of distances as
far as 25 km across uneven and steep terrain in unpredictable and potentially dangerous weather. Wind
speeds as great as 60 mph and freezing rain are not uncommon at Augustine in the summer, andparticipants are reminded that they must provide their own gear (sturdy tent, sleeping bag, sleeping pad,boots, backpack, water bottles) to meet the challenges of the weather.

For nearly ten years on Kamchatka, our team of geoscientists has been collecting data on
tsunami deposits, both historical and pre-historical. Abundant Holocene tephra on Kamchatka
permit constraints on the timing of both historical and prehistoric tsunamis, which we take asproxies for subduction-zone earthquakes. Millennial-scale histories are one goal of these studies(e.g., Pinegina and Bourgeois, 2003; Pinegina et al., 2003a&b). Another goal is enhanced
investigation of historical tsunamis (as catalogued by Zayakin and Luchinina, 1987; plus 1997
Krontoskoye), both to generate benchmarks for older tsunami deposits, and also, as shown below,
to elucidate earthquake-tsunami linkages during these remote, recent events.
1969 Ozernoi earthquake and tsunami
On 22 November 1969, 23:09:35 GMT (locally midday, 23 November), an earthquake
jolted the Ozernoi Peninsula, with local shaking of 7-8 MM (Fedotov and Gusev, 1973). The
epicenter was located at 57.8oN, 163.6oE, just off the Ozernoi Peninsula. Fedotov and Gusev(1973) interpreted this earthquake as an oblique slip event with a significant component of left
strike slip, but as early as 1975, it had been reinterpreted as a thrust fault (Cormier, 1975), basedon data from global and Canadian seismograph networks. Using body waveform analysis,
Daughton (1990) also found a thrust fault-plane solution, striking N50o-80oE and dipping 5o10oNW, and assigned a moment magnitude of 7.8. Various magnitude for this earthquake havebeen published (7.3-7.8); a tsunami magnitude Mt=7.7 based on the tsunami height at Hawaii isconsistent with a moment magnitude of 7.7-7.8.
The 1969 Ozernoi earthquake was followed by a tsunami with local runup reported to be
5-7 m from the village of Ivashka south around the Ozernoi Peninsula to the Ozernaya River, anda local maximum of 10-15 m south of Cape Ozernoi (Olkhovaya River) (Zayakin, 1981). Runupwas 1-3 m north to Lavrova Bay and southeast to Bering Island, and the tsunami was recorded ontide gages in the town of Ust’-Kamchatsk and faintly in Petropavlovsk-Kamchatskiy. Based on thepresence of tsunami deposits above the 1964 Shiveluch tephra or the 1956 Bezymianniy tephra,
we have expanded the runup catalogue for this event to all our field sites in the southwest Bering
Sea. Moreover, we have evidence of post-1956 subsidence at the northern and southern extremesof the Ozernoi Peninsula, which we interpret to be co-seismic with 1969 event.
