Supplementary worked examples · no numerical question found in the available 12 TEE sittings

**What the available papers show:** the 12 recovered TEE sittings (1 December 2022 to 10 July 2026), containing 194 question parts, ask for explanations, comparisons, sketches, measures, checklists and case applications. No question in that set supplies values and requires a numerical calculation. The 1 December 2022 Q2A [10 marks] asks for the disaster equation and its components with an example; it is a theory question. This describes the available papers, not a restriction on a future examiner.

These examples can make a taught formula easier to understand. They are not a required numerical paper pattern and carry no claimed exam marks. For TEE, finish the core theory, diagrams, case answers and actual PYQs before spending time on the extended sums.

| Examples | Source status |
| --- | --- |
| Magnitude comparisons — optional authored practice | M2 PDF p 55 teaches the tenfold amplitude relation. The numerical values below were added for explanation; none is a recovered PYQ. The approximate energy-ratio relation is an external scientific extension (USGS), not a formula explicitly found in the supplied lecture text. |
| Seismic moment — optional lecture-formula practice | M2 PDF p 55 teaches seismic moment and moment magnitude. The three sets of values below were authored for practice, not taken from a recovered question paper. SI conversion and explicit unit conditions clarify the lecture formula. |
| Runoff — lecture-adapted and authored examples | The first two examples adapt the barren-land and township values in M2 PDF p 88, with the unit error corrected. The percentage-increase request, time conversion and 20-hectare example add practice. These are lecture examples or authored extensions, not PYQs. |
| Channel discharge — optional lecture-formula practice | M2 PDF p 100 prints Q = A × V in the desilting discussion. It supplies no drain dimensions or worked numerical. All three numerical scenarios below were authored for understanding, not recovered from exam papers. |
| Risk relationships — optional illustrative arithmetic | M1 PDF p 33 gives probability × impact; pp 34–40 explain disaster-risk components and capacity. All numbers below were authored as illustrations. The actual 1 December 2022 Q2A [10 marks] requires a conceptual explanation and example, not a numerical answer. |
