All oral and poster presentations concern deep seismic techniques for imaging and constraining the structure, composition and tectonics of the continental lithosphere. The focus of the scientific program will be on studies of the Earth°«s crust and lithosphere using the full range of seismic imaging methods, and on the integration of these studies with other geophysical techniques (e.g., MT and passive seismology) and geological data.

Science Themes

1. Japan Session
Outlines of geophysical features and geological evolution of Japanese islands (Key note only).

2. Active Continental Margins
Including results from subduction zones, accretionary complexes, forearc basins, volcanic island arcs, back arc basins / ridges and vertical transform orogens. Including, but not limited to, reflection, refraction and OBS studies in these terrains.

3. Intra-continental Collision and Accretion
Continent-continent collisional belts. Involving crustal thickening, heating and internal deformation, the dynamics at the crust-mantle interface, and faults and fault zones which may define major discontinuities.

4. Continental Rifts and Basins
The geometry of rift basins, their extensional fault systems, bounding faults and internal structures. Also including features of the underlying layered lower crust.

5. Passive Continental Margins
Focusing on the geometry of passive margins (symmetrical or asymmetrical) their internal faults, the role of the middle / lower crust, the amount and distribution of extension on a crustal and lithospheric scale, deformation (pure shear versus simple shear). Including, but not limited to, reflection, refraction and OBS studies in these terrains.

6. Integrated Multidisciplinary Case Studies
Case studies that show the use of the wide angle range of seismic imaging studies that have been coupled with other disciplinary techniques. These techniques include, but are not limited to, magneto-telluric studies, potential field surveys, geochronological studies, thermo-mechanical modeling and rock properties analysis. The seismic imaging can include a range of techniques including °∆high-resolution°« surveys, passive and active source surveys, two- and three-dimensional tomography studies.

7. The Continental Mantle
Studies of the deep lithosphere using the range of seismic techniques available. Also including studies involving mantle xenoliths and the core, and addressing issues such as nature of Moho, intra-mantle reflections and mantle characteristics.

8. Numerical Modeling of Heterogeneity and Anisotropy
Forward and inverse modeling of seismic attributes; synthetic seismogram modeling, and other numerical techniques.

9. Innovative Seismic Acquisition and Processing Techniques.
Those topics related to data collection and processing. Covering deep seismic survey design, 3D deep seismic data collection and processing, full wave-field recording and processing, wide-angle surveys and three component data. Including topics such as the meaning of deep reflectivity, differences between vertical-incident and wide-angle data sets, velocity differences, imaging steep faults, improving single/noise and active and passive sources.

10. Seismic Investigations Related to Mineral Resources and Volcano-plutonic System
The role of deep seismic surveys in understanding the role of the deeper crust in mineral and energy distribution. Including issues involving global metallogeny, geodynamics and ore deposit evolution, beyond oil exploration ? the basement, mineral deposits and seismic studies. Also addressing the fundamental issues of imaging and modeling of field systems.

11. Subduction Structures of Megathrust Zones (sponsored by JAMSTEC and NIED)
Seismic images at the subduction megathrust zones from reflection and wide-angle reflection/refraction surveys, and tomography studies. Addressing the detailed mapping of the source areas of megathrust earthquake.

12. Seismic Investigations for Disastrous Earthquake Areas (sponsored by NIED, ERI and JAMSTEC)
Results from seismic investigation in disastrous earthquake areas. Imaging and mapping of source and active faults and regional characterization in disastrous earthquake areas by seismic surveys using active and passive sources.

13. Classic Transect (sponsored by IGCP 474 project)
The process of documentation and description of °∆Classic°« seismic transects throughout the world. Covering issues including °∆what are their characteristics°« and °∆what we have learnt from them°«.

14. Japan Transect (poster session only)
Results of seismic imaging and geological surveys in Japan to traverse Japanese islands from trench to back arc. The seismic imaging with high-resolution surveys, passive and active source surveys, two- and three-dimensional tomography studies. This is a poster session only.

Oral Presentations

Program of oral presentation is click here.(pdf 342KB)

All talks will be held in the auditorium (at the Conference floor, see the map of Shonan Village Center). The time allotted to each presentation is 20 minutes including the short questions (except for Japan session).

Audio-visual equipment

°°The Conference Center is equipped with one projector for digital computer presentations (e.g., Powerpoint), one 35 mm slide projector, one overhead projector and two screens.

Speaker ready room

°°A room in the Conference Center is available for pre-projection. Speakers should bring the file containing their talk to a meeting organizer in the pre-projection room via CD or memory stick. Speakers presenting in the morning should hand in their file at least a day before their presentation. Speakers presenting in the afternoon should hand in their file before the beginning of lunch break.

Poster displays

Posters will be displayed in the Conference Center. All posters are allocated one side of 2.40 m width x 1.20 m height board (The exact size of the poster board is 2.40m x 0.9m, however a poster with a size of 2.40 m width x 1.20 m height can be displayed). Poster presentations will be held in two periods. In Poster Session 1, posters should be put up on Monday 25th morning and must be taken down before 22:00 on Tuesday 26th. In Poster Session 2, posters should be put up on Wednesday 27th morning and must be taken down before 12:00 on Friday 29th. Poster presenters may locate their poster board by their number in the program.

Ad hoc meetings and presentations

Following previous Symposia as in Mont-Tremblant/2004, it is also our aim to stimulate debate on key points that can have important influence in our future research. Therefore, three special interest group discussions have been planned. Anyone wishing to raise additional topics for discussion should contact one of the conference organizers before dinner on the Monday night.

Monday 25, 20:00-21:30 Seismic investigations in Asia: upcoming efforts and opportunities for collaborations (Hiroshi Sato and David Okaya).
Tuesday 26, 20:00-20:30 Next and Future Meetings (Organizing Committee)
20:45-22:00 TopoEurope and EuroArray (Hans Tybo)
Wednesday 27, 21:30-23:00 Organizing the next CCSS workshop (Colin Zelt and John Hole)
The subject of our meeting would be to discuss plans for organizing the next "CCSS" workshop (Commission on Controlled-Source Seismology). This meeting has been going for many years and is the "techniques" meeting for the deep seismic community. J. Hole and C. Zelt organized the previous workshop in 2003 (http://crust.geol.vt.edu/hole/ccss/) and they need to find someone (or group) who would be interested to host the next meeting.
Thursday 28, 20:15-22:00 IGCP474 Business Meeting (Bruce Goleby)
IGCP Project 474, "Images of the Earth's Crust & Upper Mantle" is aimed at providing ready access to seismic images of the Earth's basement geology, deep crust and upper mantle, with interpretations of these data contributing to more informed debate on tectonic processes, the natural environment, natural hazards and the sustainable use of natural resources. IGCP Project 474's seismic images of the Earth's basement geology, deep crust and upper mantle are available via its web site http://www.earthscrust.org/. This business meeting will discuss IGCP Project 474 future plans.

Publication of meeting volume

The Organizing Committee has made preliminary arrangements with the publisher of Elsevier journal Tectonophysics for a Special Symposium Proceedings issue. This issue will be similar to those already published from previous Symposia. In order to ensure the widest dissemination of the results presented in this Symposium we strongly encourage the participants to publish their presentations.
°°All those planning to submit a paper to the Proceedings Volume will be asked to indicate the probable authorship and title during the meeting.
°°Because the time to publication is controlled mainly by the speed on initial submission and because we wish to publish the volume one year after the meeting, we require the papers be submitted no later than December 15th. All manuscripts will undergo rigorous external review, following the standard Tectonophysics procedure.
