One such scenario that could require the use of SOS is in the aftermath of an earthquake. Knowing how to signal for help in an emergency situation - even when tapping out SOS in morse code is the only option - can lead to being rescued. In 1927, SOS was replaced by the spoken word “mayday” due to advancements in technology and the phasing out of the telegram.ĭespite being replaced, SOS is still a commonly used signal for help around the world. Before then, each country used its own emergency alert signals, which understandably led to some confusion. SOS wasn’t even supposed to be used in letters originally, but rather in morse code (… – – – …).ĭuring a radiotelegraph conference on November 3, 1906, SOS became the internationally recognized sign of distress. Many people believe SOS stands for “save our souls” or “save our ship” however, in truth, it isn’t an abbreviation for anything.
