Witwatersrand Local Tremors


IN an article on “The Earthquake in Turkey”1 Mr. E. Tillotson refers to the idea that violent earthquake shocks appear to be followed almost immediately by sympathetic shocks in various parts of the world. In this relation he points out that on the same day as that on which the earthquake occurred in Turkey, December 27, 1939, earthquakes occurred in San Salvador, Los Angeles, Tangier and “Between December 27 and 28, twenty-five earthquakes and earth tremors shook the gold mining district of the Rand near Johannesburg in South Africa”.
