Puerto Rico Trench Gravity Anomaly

Tectonic Parameters

Subduction Angle (θ) 45°

Dip angle of the subducting North American plate.

Oceanic Crust Density (ρ_c) 2.9 g/cm³

Density of the subducting oceanic crust.

Asthenosphere Density (ρ_m) 3.3 g/cm³

Density of the surrounding mantle material.

Trench Depth (z) 8.4 km

Maximum depth of the oceanic trench.

The Puerto Rico Trench exhibits the largest negative free-air gravity anomaly on Earth (-380 mGal). Can your model reproduce this extreme value?
