If Grooberson was a Shandor, then I would imagine he'd know exactly what was causing the Earthquakes and would be keeping a low profile so as not to be interfered with in his attempt to bring Gozer back (assuming that's the goal).
I think he represents us, the fans. A super geekyly obsessed fan of the Ghostbusters. He knows all the details of their adventures, he knows what they were using to do their busting (only on a superficial level, he doesn't know all the technical aspects of the equipment), so when disaster strikes he's super excited to help the kids find their way in the ghost busting world. Obviously he'll freak out when he'll discover that the family is a whole bunch of Spenglers.
There was a photo (https://media.vanityfair.com/photos/5e2 ... mbed03.jpg) showing Grooberson and Callie looking at a map. If you look in the foreground, there are a bunch of 80s era gadgets. I think this is stuff from Egon's underground lab. My theory is that Grooberson finds a map detailing the Shandor mine, and Grooberson figures that must be the source of the earthquakes. I think he will go to the mine and get's chased back to his car by a terror dog.
