What is the Seismogenic Zone Experiment?

Most of the world’s great earthquakes occur in subduction zones. Although plate tectonics provides the underlying explanation, only a small portion of the plate contact generates earthquakes; this portion is the Seismogenic Zone Initiative (SEIZE). The seismogenic zone provides both fundamental scientific challenges and is of great societal relevance. SEIZE will address the following questions:

What is the nature of strong, locked parts of seismogenic zones?
What are the temporal relationships among stress, strain, and fluid composition throughout the earthquake cycle?
What controls the up- and down-dip limits of the seismogenic zone?
What is the nature of tsunamigenic earthquake zone?
What is the role of large thrust earthquakes in mass flux of material in the subduction system?

The Central American and Nankai Trough (Japan) areas were selected for focussed study by the geoscientific community during a workshop in 1997 (see the SEIZE science plan for selection procedure and criteria).
