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.

N

Required integer. Converter resolution.

FS (V)

Required number in V. Peak-to-peak full-scale voltage.

The cited overview of Seismology supplies background for the terminology and domain context used by this tool.^[1]

Digitizer LSB size and clip voltage from bit depth and full-scale range. Inputs are interpreted exactly in the displayed units and the calculation returns the following fields without presentation rounding.

LSB (µV)

Returned number in µV. Least-significant-bit weight.

Clip (V)

Returned number in V. Positive rail clip level.

Counts

Returned number. Maximum positive code.

• 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.
• N must be at least 1.
• N must be no greater than 52.
• FS must be at least 0.
• Use finite inputs in the displayed units, preserve source measurements and assumptions, and independently verify consequential decisions.

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.
