Magnitude Scaling Saturation Check Tool
Flag whether a rupture length implies magnitude beyond the empirical saturation limit (~M7.8) of simple linear scaling.
Description
Flag whether a rupture length implies magnitude beyond the empirical saturation limit (~M7.8) of simple linear scaling.
Magnitude Scaling Saturation Check Tool is a focused tool for the following task. Flag whether a rupture length implies magnitude beyond the empirical saturation limit (~M7.8) of simple linear scaling. It reports M_linear, Saturated from the values you provide rather than inventing measurements, coefficients, or professional judgment that are not part of the input.
When to use Magnitude Scaling Saturation Check Tool
Use this seismology calculation to reproduce a stated convention, screen observations, or compare scenarios whose units, coordinate conventions, catalog selection, and model assumptions are known.
- L (km)
- Required number in km. Rupture length.
- M_sat
- Optional number. Saturation magnitude cap.
The cited overview of Seismic magnitude scales supplies background for the terminology and domain context used by this tool.1
How Magnitude Scaling Saturation Check Tool works
Flag whether a rupture length implies magnitude beyond the empirical saturation limit (~M7.8) of simple linear scaling. Inputs are interpreted exactly in the displayed units and the calculation returns the following fields without presentation rounding.
- M_linear
- Returned number. Uncapped linear-scaling magnitude.
- Saturated
- Returned boolean. Whether the estimate exceeds the cap.
Limitations and assumptions
- Earth structure, source geometry, path effects, site response, instrument response, catalog completeness, uncertainty, and the fitted range can dominate the accuracy of simplified seismic calculations.
- L must be at least 0.
- Use finite inputs in the displayed units, preserve source measurements and assumptions, and independently verify consequential decisions.
Alternative or Complementary approaches
For analysis or hazard decisions, retain uncertainty and provenance and compare the result with waveform processing, calibrated regional models, and guidance from qualified seismologists or the responsible agency.
