Uneventful flight to PDX; assigned the HHOOD RNAV arrival by Seattle Center. When told to contact PDX Approach was taken off the HHOOD arrival just after HHOOD and to continue descent to 5;300 FT and go direct HANAH on the [Runway] 28L approach. Reset altitude from 6;700 to 5;300 and proceeded direct HANAH. While level at 5;300 prior to HANAH received GPWS warning TERRAIN; TERRAIN; PULL UP. I selected TOGA autopilot OFF and climbed to approximately 6;300. Event over; advised ATC; and was re-cleared to 4;000 FT. Uneventful approach and landing.I noticed radio altimeter came into view and rapidly went from 2;500 to 1;400 just before warning. ATC said highest obstruction was about 4;300 and MVA was 5;300. Suspect rapid terrain increase was the reason for the warning.
An A320 received an EGPWS TERRAIN; PULL UP warning and executed the escape maneuver at 5;300 FT on the PDX Runway 28L ILS prior to HANAH. ATC reported a 4;300 FT terrain feature at that point and a MVA of 5;300 FT.
