Where will Mauna Loa erupt from?

Scientists can't tell far in advance when and where Mauna Loa will open new vents and erupt. Vents generally form along the volcano's rift zone. That's where the mountain is splitting apart, the rock is cracked and relatively weak and it's easier for magma to emerge.
