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).
