Thanks for the map - however - on the seismic charts,
including this other one
http://neic.usgs.gov/neis/qed/

there are depths such as
235.7 PERU-BOLIVIA BORDER REGION
69.5 NEAR COAST OF NICARAGUA
111.6 ECUADOR

so why the consistently 'rounded-off' figures such as 10 and 35???
Surely not all faults occur at these consistent depths?
Something is wrong with the system?
