Environment - Non Weather Related; Procedure
On the Janny 5 arrival into BUR on radar vectors off of wabbit. ATC vectored us to cross over the hills/mountains at 5;000 ft. The aircraft gave an aural 'terrain pull up' message and then promptly went away. I saw the RA come down to 1400 ft. which would have caused the warning as the aircraft was in a clean configuration. We were in VMC conditions.Crossing the peaks of the hills/mountains on radar vectors in the clean configuration at 5;000 ft. caused the warning.Maybe the MVA needs to be raised in that location to prevent RA's from occurring. We need 2;000 ft. separation from terrain in mountainous areas and the RA will set off the terrain warning in a clean configuration when less than 1;500 ft. above the ground.
Air carrier Captain reported receiving a GPWS terrain warning on descent into BUR; and recommended ATC use a higher altitude for arrivals over terrain.
