The magnitude 8.8 earthquake in Chile was so powerful that it may have shortened the length of the day by 1.26 microseconds and moved the Earth’s figure axis by 8 cm or 2.7 milliarcseconds. The largest earthquake in recent times, a massive 90 second quake on Feb 27 in Chile, generated a blackout that affected 93 percent of the country.
Chile’s 8.8 earthquake moved the entire city of Concepción 3.04 metres or 10 feet to the west. The capital Santiago shifted almost 24 centimetres or 10 inches west. Chile’s territory could have expanded 1.2 km² as a result.
