 Context: The oldest evidence of earthquakes was discovered in 3.3 billion-year-old rocks from Africa, indicating early plate tectonics.

 

What is the Barberton Greenstone Belt?

The Barberton Greenstone Belt (similar to New Zealand’s geological features) is a geological formation in southern Africa (on the eastern boundary of the Kaapvaal Craton in South Africa.) that provides one of the most extensive geological records for Earth between 3.2 billion and 3.6 billion years ago. It consists of ancient rocks and provides evidence of early Earth conditions, including signs of seismic activity, early plate tectonics, and potential impact on the evolution of life.

The Barberton Greenstone Belt’s outcrops were added to UNESCO’s World Heritage Sites list in 2008 under the name ‘Barberton Makhonjwa Mountains’.
