Q # 1: Why do plates move with different velocities?

A # 1: I believe that the two forces, namely slab pull and slab suction that causes plates to move at subduction zones are responsible for plates moving at different velocities. At subduction zones plates are being subducted faster and thus the plates move with relatively larger velocities. Whereas at divergent boundaries, the slab pull effect is minimal because it is remote and thus we observe smaller values for the plate velocities.

Q # 2: Don’t you think that the results obtained for Arabia is less accurate, and this less reliable than other regions in this study?

A # 2: Due to the fact that Arabia is an area on minimal seismic activity relative to the region, it is not as widely covered by seismic stations and other areas such as Turkey. Therefore I would tend to be suspicious about the results concluded for Arabia.

Q # 3: Why is the DSF rate higher in comparison with regional GPS studies?

A # 3: This could be due to an active opening of the gulf of Suez rift but it could also be due to miscalculation of the DSF using the available data.
