Timeline
Canterbury mainshock reshapes the city
**2010-09-04** — A magnitude-7.1 earthquake strikes the Canterbury region and damages Christchurch, starting a prolonged sequence of aftershocks and inspections. The event does not kill in the same numbers as February, but it weakens structures, unsettles confidence, and sets the stage for the later disaster.
Shallow rupture beneath the Port Hills
**2011-02-22** — A magnitude-6.2 earthquake ruptures at shallow depth near Christchurch, producing intense ground motion in the central city. Its proximity and vertical acceleration make it more destructive than its magnitude suggests.
Lunch-hour collapse of the CTV Building
**2011-02-22** — The CTV Building collapses and becomes the deadliest single structure in the disaster. The failure traps occupants and later becomes a focus of the Royal Commission's inquiry into design and construction.
Central city buckles and glass storms the streets
**2011-02-22** — Façades fall, roads crack, and dust fills the CBD as the earthquake spreads damage across the urban core. The shaking lasts only seconds, but it leaves the center of the city functionally shattered.
Search and rescue begins under unstable ruins
**2011-02-22** — Emergency crews, police, firefighters, and volunteers begin searching collapsed buildings while aftershocks and unstable structures remain a threat. Triage, cordons, and improvised coordination define the first rescue phase.
Mass evacuation from the CBD
**2011-02-22** — Workers, residents, and visitors are moved out of damaged areas as authorities close roads and clear unstable buildings. The evacuation exposes how many people had been concentrated in the city center at the time of the quake.
First casualty counts and missing lists
**2011-02-24** — Officials begin assembling the dead and missing as hospitals and police try to reconcile names, locations, and recovery sites. The count remains provisional for days as identification and searches continue.
Royal Commission hearings open
**2011-04** — The Royal Commission begins examining building failure, design choices, and regulatory oversight. Testimony and engineering evidence establish the inquiry as central to understanding why the disaster was so lethal.
Commission findings on building failure
**2012-11** — The Royal Commission releases conclusions that reshape public understanding of the CTV Building collapse and other failures. The report drives changes in assessment, strengthening, and the handling of seismic risk in buildings.
Urban rebuild and seismic reform
**2012-2013** — Christchurch and New Zealand revise building practices, engineering assumptions, and recovery policy in response to the earthquake. The city center remains a landscape of demolition and reconstruction while national standards evolve.
Fourth anniversary remembrance
**2015-02-22** — Public commemorations honor the dead and the survivors while the city continues its long recovery. The anniversary becomes part of Christchurch's collective memory and a reminder of the disaster's continuing presence.
Official death toll rises toward 185
**2011-02-23** — As recovery and identification continue, the death toll climbs to the final officially recorded number of 185. The figure becomes the central measure of the earthquake's human cost, though it only begins to describe the wider damage.
