Epidemics and biological hazards inside disaster risk management
Biological and epidemic hazards in disaster risk management
The Sendai Framework names biological hazards beside natural and technological ones, and the Bangkok Principles of 2016 turned that into practice.

- Terrain Surface height in whole metres on the plan's grid of cells about 785 by 985 metres; the Taurus foothills and the Amanos range frame the fault valley, the box rises from 59 to 3,044 m. Produced using Copernicus WorldDEM-30 © DLR e.V. 2010–2014 and © Airbus Defence and Space GmbH 2014–2018 provided under COPERNICUS by the European Union and ESA; all rights reserved. read 2026-10-17. Estimate: A digital surface model: trees and roofs are in the heights. Relief exaggeration is printed on the stage.
- Reference earthquakes The two main shocks of 6 February 2023: origin, magnitude, depth, time and review status from the USGS detail record, the hypocentre drawn below the ground. U.S. Geological Survey Earthquake Hazards Program. read 2026-10-17. Estimate: Reported solutions as reviewed by the USGS; magnitudes and depths carry the USGS stated uncertainties, which the event page links rather than restates.
- Population count 2020, WorldPop 1 km People per cell in 2020, summed from the national 1 km raster of Turkiye on a grid of 160 by 120 cells; the Syrian part of the box, south of the border, is empty because the national file stops there. WorldPop (www.worldpop.org), University of Southampton, 2020 UN-adjusted 1 km, CC BY 4.0; summed per cell. read 2026-10-17. Estimate: A modelled 2020 estimate adjusted to UN totals; never a count of people affected; cells outside the national file are empty.
- Earthquakes M4.5 and above, past week (live) Reviewed and automatic seismic solutions of the past week inside the box, with magnitude and depth, read from the world feed and filtered to the box in your browser. U.S. Geological Survey; reported detections, automatic solutions preliminary; never a warning. Live: this page requests earthquake.usgs.gov when the layer is opened; the data date is printed with it. Estimate: Reported detections; automatic solutions are preliminary; never a warning.
- USGS ShakeMap intensity contours The ShakeMap MMI contours of each main shock draped on the terrain, read from the cont_mmi.json file the event's detail record names; the exposure instrument reads the PAGER exposure table the same record names. U.S. Geological Survey ShakeMap and U.S. Geological Survey PAGER (preliminary, automatically generated; see the USGS disclaimers), with the product version and time. Live: this page requests earthquake.usgs.gov when the layer is opened; the data date is printed with it. Estimate: Preliminary and automatically generated; PAGER levels and exposures are USGS estimates with stated uncertainty, never a warning or a loss figure of the Academy.
Why this place: The sequence of 6 February 2023 put two events of M7 and above on the East Anatolian fault within nine hours, with reviewed USGS solutions, ShakeMap, PAGER and ground-failure products and a red PAGER alert. One box of about 140 by 130 kilometres holds both epicentres, Kahramanmaras and Gaziantep and the fault valley between the Taurus foothills and the Amanos range, so intensity against distance, exposure and warning lead time are taught on one place. Copernicus DEM GLO-30 covers the box in six tiles and WorldPop gives a 2020 count per cell for the Turkiye part.
Flat plan of the same data: relief, the two epicentres with magnitude and depth, the WorldPop count grid and the numbers below. The 3D twin opens on devices that can draw it, once its data and code have been checked.

The subject, methods and measures and debates and bodies
The field and its scope
For disaster managers, public health emergency officers and planners who must assess epidemics alongside natural hazards and keep health services running when the two coincide.
Quantities and units
Methods and their limits
Each method is listed with what it assumes and where it fails.
What the field debates
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.
From shelter crowding to an outbreak size: how space per person sets the reproduction number, the attack rate and the care a shelter needs
The number of displaced people and the space each has set the contact rate; the contact rate scales the reproduction number; the reproduction number through the SIR dynamics sets the attack rate; the attack rate times the population and a severity share gives the care the health cluster must plan for.
