[During] approach; RNAV RWY 30 HTS in VMC night conditions; [we received a] terrain caution. [Position was] approximately 2-3 nm from HIBTI; our altitude was 2;200 feet descending to 2;100 feet. At the same time the Tower gave us a 'low altitude alert; check your altitude'. The escape maneuver was initiated; but almost immediately; the terrain caution stopped and we were able to finish the approach.EGPWS Caution; Tower low altitude alert.Started escape maneuver; almost immediately terrain caution stopped. At this point; we were able to continue a stable approach. We were in VMC conditions night with runway in sight at the time of this occurrence. The RNAV approach was being accomplished due to the GS out LOC only 30 was other option. After a discussion with other crew members about the terrain caution; I was told that that caution on that approach was a normal occurrence; due to a rise in the terrain in that area or possibly the Tower that is just slightly south of the final approximately 3 nm from HIBTI. We need to investigate this approach and also the LOC 30 approach and if needed the approach procedure should be changed.
EMB-145 Captain reported a GPWS terrain warning and an ATC low altitude alert on a night visual approach to Runway 30 at HTS.
