The Good Friday earthquake of March 27, 1964, hit Anchorage hard at a magnitude of 9.2, killing 115 people and causing $116 million in damages ($750 million in dollars). The earth-shaking event lasted nearly five minutes; most structures that failed remained intact for the first few minutes then failed with repeated flexing. It was the world's second-largest earthquake in recorded history. Broadcaster Genie Chance has been credited with holding Anchorage together, as she immediately rushed to the Anchorage Public Safety Building and stayed on the KENI airwaves for almost 24 continuous hours. Chance, effectively designated as the public safety officer by the city's police chief, was instrumental in Anchorage's relief and recovery efforts as she coordinated response efforts, connected urgent needs with available resources, disseminated information of available shelters and food sources, and passed messages among loved ones over the air, reuniting families. Because the city and surrounding suburban area was built on top ground consisting of glacial silt, the prolonged shaking from the earthquake caused soil liquefaction, leading to massive cracks in roadways and collapse of large swaths of land. One of Anchorage's most affected residential areas, the Turnagain neighborhood, saw dozens of homes originally at 250 to 300 feet above sea level sink to sea level. Rebuilding and recovery dominated the remainder of the 1960s.
