Earthquake measurer.

Due to the scale at which they take place, natural disasters can be challenging to measure. Consider earthquakes: you can't ask how high an earthquake is, or quantify the weight of tectonic plates shifting against one another. What seismologists try to do instead is to measure the energy released by a quake.
