Education in physics and geosciences can be effectively illustrated by the analysis of earthquakes
and the subsequent propagation of seismic waves in the Earth. Educational seismology has matured to
a level where both the hard- and software are robust and user friendly. This has resulted in
successful implementation of educational networks around the world. Seismic data recorded by
students are of such quality that these can be used in classic earthquake location exercises, for
example. But even ocean waves weakly coupled into the Earth’s crust can now be recorded on
educational seismometers. These signals are not just noise, but form the basis of more recent
developments in seismology, such as seismic interferometry, where seismic waves generated by ocean
waves—instead of earthquakes—can be used to infer information about the Earth’s interior. Here, we
introduce an earthquake location exercise and an analysis of ambient seismic noise, and present
examples. Data are provided, an…
