There seems to be one more informed that my friend Google and that is regular PEDP reader Grant Slater. He sent me the following:
It is called “Moregrove Quarry” owned by Lafarge Aggregates. A brochure titled “Moregrove Quarry: 50 Years” was published in 1992. Which would make the quarry 71 years old this year. The quarry is on the Moregrove Fault.
He also sent me a link to an online article on the Moregrove Fault and I quote the following from it.
“There are three ancient fault lines in Port Elizabeth where some slight movements can still occur. One of them, the Moregrove fault, runs along the Port Elizabeth beachfront from Pollok Beach, Summerstrand, along the shoreline, through the Baakens Valley and ending at the Moregrove quarry near the Kragga Kamma interchange. The water which continually runs across Lower Valley Road near the old PE Tramways building is underground water seeping to the surface through the Moregrove fault. Another, the so-called Chelsea- Noordhoek fault, runs parallel to the Schoenmakerskop coast, while a third fault runs in the Coega area.”
You are just so good with this geocaching. I don't even know the first thing about it. (Just as well, my husband would never get a meal or clean clothes if I latched onto another hobby, LOL!) Greetings, Jo

Thanks Grant. I'll update the post with the info
Very interesting article, Grant. I come from Joubertina myself and we had a tremor there in September 2001, also just enough to rattle Ouma's portrait on the wall.
PS would someone be able to plot these faults on a map for interest's sake?
