Narrative:
I was working two sectors combined with a lot of popcorn style weather popping up all over. There was a very high volume of IFR traffic with many VFR aircraft both talking to center and not. Many aircraft were deviating and asking for deviations and I had many traffic calls to make. Multiple times before the incident took place; I had to use merging target procedures to make sure that VFR targets did not merge with each other at the same altitude. At the time the incident took place; I was specifically focused on 2 VFR aircraft merging at the same altitude. While this was going on; aircraft X flew into an area where the MVA (minimum vectoring altitude) was 6;400 feet at 6;000 feet. When I noticed this; I issued a low altitude alert and climbed it to 7;000 feet. To prevent this event from happening again; I have to be much more aware of aircraft flying southbound in hazard below 7;000 feet. Be more aware of my limitations as a controller and request a tracker when the traffic is very high and complex. Dwell lock all southbound aircraft below 7;000 feet traveling southbound in hazard.
