This resource provides an abstract. This study examines seismic waves from a segment of the Middle America subduction zone below Central America that are capable of producing strong earthquakes. Results confirmed the depth of the crust-mantle boundary and mantle seismic velocities in the region. It was found that decreased seismic velocities are evidence that fluid affected nearly 15-25 percent of the mineral structure, leading to serpentinization. This data can contribute to improving earthquake hazard estimates for the area.
