Expect more tremors - experts

2014-08-09 19:11

Johannesburg - Seismologists said more tremors are expected to hit the country again over the next few days, the Saturday Star reported.

"I expect there would be at least two or three magnitude four events coming up within the next week or two," technical director of earth science consulting company Umvoto Africa, Dr Chris Hartnady told the newspaper.

"Very often one finds in quake areas the main shot delivers a damage blow to some buildings but then quite often it’s the smaller aftershocks that finish them off."

Hartnady said if people reoccupied damaged buildings before the aftershock sequence closed, they would be putting their lives in danger.

Council of Geoscience seismologist Michelle Grobbelaar agreed that more earthquakes were expected, the publication reported.

"The rule of thumb in seismology is that history repeats itself. We can get those magnitudes (of 5.5) coming back. We can't say when it will happen but we can expect another one," she was quoted as saying.

A 31-year-old man was killed in a mining village near Orkney, North West on Tuesday when the 5.5 magnitude earthquake struck the region.

At least 34 miners were injured by the earthquake, and more than 600 houses were damaged.

Grobbelaar said mining areas like the North West province had more than 80% seismicity.

Aftershocks in the Orkney and Klerksdorp areas were being monitored, she said.

    Apparently Julius Malema is complaining that sum provinces didn't receive the earthquake .this is what he had to say.... It is not fair that some places dd not receive the earthquake, this is how poor the delivery of services in South African has become. The ANC is corrupting us and taking our natural disasters to themselves due to greed . We wil not sit down and watch the president Jacob Zuma and his people take our things .if u voted EFF these things would not happen . We will fight for our rights because we the Economic freedom fighters its our mission to fight against the ANC and its corrupt leaders... #bring back our earthquake#

      At last , someone with a sense of humour. Careful you do not label yourself as racist. There is always one tit out there who cannot see the forest for the trees and will attack your wit with furious misguided stupidity. Otherwise known as a troll. Thanks for the entertaining comment.

    Has no -one been watching this ? No - one in this country been keeping an eye, even though we’re not a country with this kind of incident. Surely someone dropped the ball !

      So far, scientists haven't been able to find a signal for earthquakes - there is no obvious sign to say that an earthquake is coming very soon. Vibrations can be detected just before an earthquake occurs, but this doesn't give enough time for people to escape. The processes that cause earthquakes mostly occur far below the Earth's surface. There are many tectonic plates - sections of the Earth's crust that rub together and cause earthquakes - and their interactions are complex. This makes earthquakes very hard to study.

    If this is true, then they should not send any miners underground in that area for a while. Also find temporary housing for the people who should not move back home. The aftershock can be more dangerous due to the damage from the first quake done.

    Experts expect more tremors or less tremors ,that's why they are called experts

  • Fanie Mthethwa - 2014-08-10 07:43

    My prediction is that there will be more predictions in the next few days.
