The event
[edit]The seismic sequence began in February 2062, known as the Three-Door Winter., following a magnitude 5.9 foreshock detected near the southern end of █lmarka island.[8] The mainshock, measuring 7.2 on the moment magnitude scale, had its epicenter approximately 12 kilometres offshore from North Harbour.[9] Seismic waves propagated rapidly toward the city center, reaching ██████████ within thirty seconds and Kaelora by minute four.[10] Residents reported a sudden, violent shaking that lasted for about two minutes before transitioning into a long-period rolling motion typical of deep-focus quakes.[11]
Shaking intensity reached peak levels in Marina Heights, where the reinforced structures suffered catastrophic shear failure. Initial reports indicated that the outer perimeter walls of several high-rise towers gave way while the cores remained intact, leading to partial collapses that trapped occupants inside.[12] By 14:36, emergency sirens had activated across ██████████ and Kaelora. A secondary rupture occurred at 14:48 near the industrial zone of North Harbour, damaging pipelines and communication towers but causing no additional structural failures in residential areas.[13] Tremors ceased completely by 15:02, leaving a landscape of debris and emergency vehicles lining the streets of Marina Heights.[14]
