Faculty of Hazards, Disasters and Resilience
A disaster is read from the event outward: the source and its shaking, the people in its reach, the minutes a warning could have bought, the response and the loss that follow.

From a rupture to a decision: how shaking becomes loss, and where a warning fits
An earthquake's magnitude and distance set the shaking a place receives; the people and buildings there turn shaking into loss; an alert arriving before the strong shaking buys seconds, and a decision made earlier buys days.

Faculty of Hazards, Disasters and Resilience
The faculty studies how natural and technological hazards become disasters through exposure and vulnerability.
Department
A body of related disciplines within the Faculty of Hazards, Disasters and Resilience, with its own courses and pathways.
Primary discipline
The discipline a course mainly teaches; a course may also teach up to two other disciplines.
Intensity
The strength of shaking at a place on the modified Mercalli scale (MMI), from felt reports and recordings; magnitude is the energy of the source, intensity is what a place experienced.
