Historical earthquakes is a list of significant earthquakes known to have occurred prior to the early 20th century. As the events listed here occurred before routine instrumental recordings — later followed by seismotomography imaging technique, [1] observations using space satellites from outer space, [2] artificial intelligence (AI)-based earthquake warning systems [3] — they rely mainly ...
