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.

04The subject
The subject, methods and measures and debates and bodies
The field and its scope
For humanitarian programme staff, coordinators, government counterparts and analysts who plan and deliver assistance to people affected by disasters and conflict, including those displaced from their homes.
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.
05The method
From a displaced population to a funded response: how litres per person, a minimum standard and appeal coverage meet in a camp
The number of displaced people divides the water delivered into litres per person per day; the Sphere benchmark says what that number must reach; the same count times a cost per person gives the appeal; the share funded decides how many are served, and the coordinator allocates the shortfall.
Start with Pictet, then Sphere Association, then Barnett.
12Questions
Questions, answers and key terms
Is study here free?
Yes. Every course and learning material of Risk Academy, led by the Nexus Consortium, is free to study, self-paced or with a cohort. Ordinary participation has no fee; paid work, internships and fellowships are separate arrangements.
What does completing a course give me?
A completion record: the course, its version, the date and what was assessed, private by default and shared by you. It stacks into discipline, department and programme achievements. A record states what was studied and assessed and does not certify competence; it is not a licence, a professional title or an employment status.
Where do the data and the places come from?
Every faculty teaches on a twin of a real place built from open data; each layer carries its provider, licence and date, and every result on the Academy states its source. Maps and figures are indicators for teaching, never an assessment of a place.
How do I take part beyond the courses in humanitarian action and displacement?
Form a competence cell of three to seven people, study a shared pathway, take a supervised assignment in the National Working Groups, or bring a cohort from your institution. For organisations.
