AGU Town Meeting: The Nankai Subduction Zone, southwest Japa, December 2000
Friday, 15 Dec., 2000 5:30-8:00 PM Rooms 270 & 272, Moscone Center. Refreshments Provided.
The Nankai subduction zone produced destructive great earthquakes in the 1940's and remains a significant societal hazard. It is one of the focus areas of the Seismogenic Zone Experiment (SEIZE) (http://www.soest.hawaii.edu/margins/SeismZone.html) and the locale of intensive recent geophysical and geological investigations. In order to inform the community about on-going projects, to highlight outstanding problems, and to encourage new collaborations we are sponsoring a discussion of current and planned research in the Nankai subduction zone. We will briefly review current 3D seismic reflection, Ocean Bottom Seismometer, and GPS programs plus recently completed and planned ODP drilling. We will follow with short presentations from the floor on current or planned research in the Nankai subduction zone and end with a freeform general discussion.
We invite all interested geoscientists to come, listen, and contribute. We are especially interested in attracting new collaborators with scientific approaches and agendas not currently being pursued.

Seismic Reflection Data from Nankai and Costa Rica/Nicaragua available via the UTIG web site August 2000
UTIG has maintained this archive since 1975 with internal funding. Because many of the original investigations were publicly funded, the majority of these data are in the public domain. In 1998, The National Science Foundation provided funds for the media costs associated with our transcription from Exabyte to Digital Linear Tape (DLT). In order to make the data publicly available, and to preserve the integrity of the data over the long term, UTIG has created this database. Currently, there are approximately 23,000 files of data, of which 3000 of the files are stacked and processed data, and the remainder being shot gathers. The data is mostly in SEG-Y or SEG-D formats.

SEIZE Article, July 1997
"The Seismogenic Zone Experiment (SEIZE) Workshop Draft Report" written by Greg Moore
"Most of the world's great earthquakes and tsunamis initiate in the zone of underthrusting or seismogenic zone of subduction zones. The Seismogenic Zone Experiment (SEIZE) hopes to understand the relationship between earthquakes, deformation, and fluid flow in this environment. SEIZE will address the following questions: 1) What is the nature of asperities? What are the temporal relationships between stress, strain, and fluid composition throughout the earthquake cycle? 3) What controls the up-and downdip limits of the seismogenic zone? 4) What is the nature of tsunamigenic earthquake zone? 5) What is the role of large thrust earthquakes in mass flux of material into (and out of) the subduction system?..."
