Example from Hong Kong

Hong Kong

The tasks is based on arrival time of P-waves and S-waves and using the information to determine how far one is from the epicentre and hypocentre. Information about epicentre and hypocentre.

This is suitable for secondary level when students are learning simultaneous equations, trigonometry and Pythagoras theorem as well as locus.

The e-textbook may embed geometry tools such as GSP to allow students to do geometric construction using technological tools and explore the general case.

Patsy Wang also suggested including videos / interviews of actual work done by professionals in determining epicentres of earthquakes. How geologists use trilateration and other techniques can show how mathematics is used by different professions - in this case by geologists.
