The Richter Scale was first developed in the 1930's by Charles Francis Richter to measure the magnitude of earthquakes in order to be prepared for the amount of damage. The Richter Scale is a base-10 scale which defines the magnitude, or amount of energy released by an earthquake. A 7.0 on the Richter Scale is a major earthquake. Each whole number on the Richter Scale represents an increase of about 10 times more energy released than the previous whole number.
In the 1970's, a scale was created to replace the Richter Scale. This was called the Moment Magnitude Scale, created by ts Thomas C. Hanks and Hiroo Kanamori to address the shortcomings of the Richter scale while maintaining consistency. Unlike other scales, there is no upper limit to the possible measurable magnitudes.

The 3 Broad Types of Tsunamis
Local Tsunami:
-Very dangerous
-Little preparation time
-Generally reaches shore within 1 hour
Regional Tsunami:
-Medium preparation time
-Generally reaches shore within 1-3 hours
Distant/Ocean-Wide Tsunami:
-Most preparation time
-Generally reaches shore in over 3 hours
