A snapshot to learn from, not a warning service

Everything here is a copy of open feeds and datasets taken when the site was last built, with its date beside it. Nothing updates by itself and nothing here is an alert. For warnings, follow your national meteorological, hydrological and civil-protection authorities.

03Recent events

Earthquakes and natural events, as of the snapshot

Earthquakes of magnitude 4.5 and above from the U.S.

  • Snapshot: copied from the feed on the date shown, not live.
  • Verified: reviewed by USGS. To verify: an automatic USGS solution that may be revised.
  • Secondary: relayed by NASA EONET from another agency; each event keeps its original source.

04The layer stack

Eleven layers that describe the same ground

Land, residents, water stress, agricultural water risk, generating capacity, heat exposure, relief, elevation, land cover, night lights and the satellite view, on one map you can filter and read.

  • Observed: measured by an instrument. Reported: stated by the operator. Modelled: computed by a published model. Estimated: derived with stated assumptions.
  • Heat exposure is ground skin temperature, not air temperature and not a heat warning.

Earth observation

The layers that describe the world

11 layers over the same ground: licensed products committed with this site, and NASA imagery loaded on request. Each keeps its measure, unit, date, source and label; none is added to another.

06Questions

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 every course?
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.
