Pipe could be broken, clogged at its outlet, filled with leaves and such, frozen up - any of those. In many cases sump pups discharge into perforated drain pipe so dischargesome of the water (or maybe all in dry times) into the ground, so if the drain pipe outlet is blocked or the pipe is crushed or such, the water might pressure up and push out through the perforations and well up out of the ground as you are seeing.

Actually, a sump pump should not discharge directly into an underground drain without an airgap (recommended at 4 inch open gap to provide enough area for free flow if the drain clogs or freezes up) at the inlet where it can overflow onto the ground if the drain pipe gets plugged up - because that can cause stalling of the pump which will can it continuously run and ovearheat, not to mention not discharging the water it needs to.

Of course, the area where the overflow would occur should be relatively impervious soil or cover material or surface splash drain or such, and drain away from the house so if the drain does block up the sump pump water will flow away from the house and not risk coming in through the foundation.

OBvious first place to look is at the pipe outlet, and where the water is coming up - pipe is usually at a quite shallow burial depth.
