When a large earthquake occurs, geophysicists have many tools at their disposal to determine the properties of the fault (or faults) that ruptured during the earthquake. The fields of seismology, which is the study of ground motions, and geodesy, the study of ground positions, are two of the main ways that geophysics researchers investigate earthquakes. Often, these efforts produce data sets which are complimentary to each other, with observations from one field confirming observations from the other. In the case of the magnitude 7.9 Offshore Kodiak Earthquake on January 23, 2018, however, these efforts have produced competing observations. This is not a bad thing – researchers often learn interesting things when observations appear to be at odds with each other.
