Eastern Lau Spreading Center (ELSC)
ELSC is a one-year deployment of 16 broadband seismometers on the islands of Fiji and Tonga and 52 Ocean Bottom Seismometers (OBS) on and around the Eastern Lau Spreading Center. The Fiji array will help us to better understand processes that occur as the slab moves through the transition zone, the Tonga array will provide insight into shallow processes near the trench, and the Lau array will allow us to image and understand the links between the subducting slab and the backarc spreading center. Together, the three arrays will provide important constraints on subduction zone processes such as slab dehydration, volatile migration, melt generation, mantle flow in the Tonga Subduction Zone/Eastern Lau Spreading Center, coupling between the overriding plate and the downgoing slab, and transition zone mineral physics.
This project is funded through the National Science Foundation's Ridge 2000 program.
