A magnitude 6.5 earthquake struck central Botswana on Monday, 3 April 2017 at 7h40pm, the largest to occur on this con-tinent in 11 years. The location was unusual as most large tectonic quakes in southern Africa are closely associated with the East African Rift System, an extension failure zone stretching from Djibouti by the Red Sea all the way to southern Mozambique. The key words here are ‘most tectonic’: the most seismically active regions in Africa are the gold mining dis-tricts along the edge of the Witwatersrand Basin, but these events are associated with mining and not with plate tectonics.

As with every New Year, we start very positive, setting new resolutions. I found that I need to set goals for myself to ensure that I stay focussed and determined to achieve my goals in the anticipated time period. These include personal, work, academic and fitness goals.
WELL DONE to all the teams that took part in the first ever SANIRE Rockbowl last year. The Event was well attended by members and contestants, with teams taking each other on in a knock out format.
The event was hosted at the Sibanye Kloof Training Centre on the 18th November 2017. A total of 7 Young Members teams entered and participated with the overall Winners being the #ROCKSMUSTNOTFALL team from SRK Consulting.
WELL DONE everyone for surviving 2016! It was one very busy year for the Western Bushveld mines, with everyone in the Rock Engineering Departments just trying to stay afloat – but we all managed to scrape though still intact.
SANIRE still remains very active in this region. At the Western Bushveld Branch meeting for 2016, a new committee and chairperson were elected. This truly was a challenge, as the previous chairperson, Naomi Ayres, had left big shoes to fill!
While trying to scout for something a little more unconventional for the year-end event, and thinking of the wealth of mining source material at our fingertips in Gauteng, we stumbled upon the KLOOFENDAL NATURE RESERVE where the Friends of Kloofendal happen to be none other than Steve and Karin Spottiswoode with Rod Kruger, so naturally the decision was made for itself!
In spite of a Saturday morning time slot, there were stalwart enthusiasts as well as newbies (thanks to our SAICE and SAIEG communication channels) who all trekked together for a geological, nature and mining history adventure. The local geology comprises somewhat disturbed quartzites, sandstone and shale (yes, indicating promises of gold-bearing reefs!). Steve was our conductor here while Karin revealed the magic of fauna and flora. Rod then gave us a tour into the early diggings of the Struben brothers, amazingly excavated by hand drills, pickaxes, shovels and explosives, and are largely still intact. Being intelligent rock engineers, we all assessed the safety of the strata and decided it was perfectly acceptable to enter and exit unscathed. Which is what we did!
