Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Seismological studies consistently show that earthquake magnitudes, including Richter and local magnitudes, can be reliably estimated and calibrated using empirical formulas and seismic wave measurements.

The analysis

The claim is a specific, empirically testable statement about earthquake seismology. Multiple papers in the literature discuss methods for calculating, calibrating, and estimating earthquake magnitudes (including Richter or local magnitude scales) from seismic data. No papers refute the core claim that these magnitudes can be estimated.
