The Richter scale was created solely for the purpose of measuring earthquakes, not tsunamis.
The Richter scale measures the magnitude of an earthquake which is another way of describing the energy released in the earthquake.

Richter Scale .
An earthquake is measured by a seismometer to determine its magnitude on the Richter Scale. The Richter is based on a base 10 logarithm. The scale defines magnitude by a logirithm of the ratio of the amplitude of seismic waves.
The Richter Scale—more appropriately called the magnitude scale—is one means of expressing the magnitude of an earthquake (i.e., the amount of energy released).
