Final answer:
The moment magnitude scale is superior to the Richter scale for measuring large earthquakes as it offers a more accurate depiction of the energy discharged during the event.
Step-by-step explanation:
True, the moment magnitude scale (Mw) is better for measuring the magnitude of very large earthquakes compared to the Richter scale. The Richter scale, while effective for smaller, local quakes, can saturate and 'cap' the measurement of very large earthquakes. This scale uses a semi-log plot with its logarithmic nature relating to the amplitude of the seismic waves and the energy they carry.
On the other hand, the moment magnitude scale gives a more accurate measure of the total energy released by large earthquakes. This scale is a logarithmic scale as well but is designed to not saturate or 'cap' at an upper limit. As a result, the moment magnitude scale is more representative of the actual size of large earthquakes, rendering it more suitable for measuring very large seismic activities.
