03The discipline

The field and its scope

For emergency managers, incident commanders, continuity planners and public communicators who prepare organisations and authorities to coordinate and lead through an emergency.

04Measures

Quantities and units

05Methods

Methods and their limits

Each method is listed with what it assumes and where it fails.

06Debates

What the field debates

07Bodies and data

Bodies that set practice, and the data they publish

Bodies and standards are named so learners can find and apply their published work; the Academy teaches their use and links to the publisher, and no affiliation is implied.

08Simulator

Run the discipline's simulator

Preparedness, emergency and crisis management's own model, as a live chart: move each parameter and read how the outputs respond.

09Maps

Build a twin of any place

Search any place or open the world; the layers and generators follow preparedness, emergency and crisis management on the planet map, the globe and in 3D.

The Kahramanmaras earthquake sequence of 2023: a flat plan of the faculty twin. Terrain 59 to 3,044 m; 2 reference earthquakes, M7.5 to M7.8; 3,643,786 people in the box, 2020; Earthquakes M4.5 and above, past week: read live when the 3D twin opens; USGS ShakeMap intensity contours: read live when the 3D twin opens. Contours every 500 metres from the elevation grid; population count 2020, worldpop 1 km as four classes per cell (edges 11, 47, 405); reference earthquakes as marks.
