Variability in subduction angles

Question 1

What is there a weak correlation between?

Answer 1

Weak correlation with subduction velocity and the subduction angle

Question 2

What is steep subduction?

Answer 2

Steep subduction is where the angle is steeper than 30° (30°-90°)

Question 3

What is flat and low-angle subduction?

Answer 3

Flat and low-angle subduction means its between 0-30°

Question 4

What can be used to generate images of subduction structures?

Answer 4

Seismic techniques are powerful in generating images of subduction zone structures and fault processes, complemented by magnototelluric imaging
