Narrative:

Arrival sectors were de-combined due to complexity since a runway is closed at sju. I was working one of the arrival sectors at the time of the event. When I expanded my scope I observed that aircraft X was at 3000 feet in a 4000 foot MVA (minimum vectoring altitude). The other arrival controller also noticed and gave aircraft X a 050 heading to a lower MVA area. The supervisor was right behind the controller monitoring the operation and I am pretty sure he saw the whole thing and did not say anything at the time. I did not hear that aircraft X was given a low altitude alert. This is a safety problem that I think we are drifting from because we are forgetting the importance of safety alerts and that the MVA's are there for a reason. We need to be reminded of the importance of issuing safety alerts and safety flow of traffic.
