Is this the service entrance panel?
Are those the service entrance wires?
If so, is there an extra ground wire, no. 4 copper, possibly green or bare running out of the panel?
The picture doesn't quite say enough to reveal whether or not the ground means is inadequate. In ordinary service, only three wires come from the poco and the neutral is bonded to ground at the main panel using a ground rod and/or a water pipe.

If this is the main panel, it only requires three wires running from the service drop (hot, hot & neutral). Ground doesn’t go back to the pole… Four wires would be required if this is the feed from the main panel to a sub panel…
– Those that say it cannot be done should stop interupting those of us who are hard at work, doing it…

One thing that you should understand. Your 3 light tester, shuretest or whatever is not checking the “ground”. It only tests the equipment grounding conductor back to the service disconnect enclosure and the main bonding jumper to the service neutral. You don’t really have a way to check the “ground” other than to look at it.
