About Earthquake Sensitivity
Seismic sensitivity refers to how responsive a seismometer is to ground motion. Different instruments and research applications use different units to measure this sensitivity.
This tool helps convert between common units used in seismology and earthquake engineering.
Understanding Earthquake Sensitivity Measurements
Earthquake sensitivity is a critical parameter in seismology that determines how well a seismic instrument can detect ground motion. The sensitivity of seismometers is typically expressed in various units depending on the measurement context and the type of instrument being used.
Common Units of Seismic Sensitivity
Counts: Digital output units from seismometers, representing the smallest detectable ground motion.
nm/s (nanometers per second): Measures velocity sensitivity, common in broadband seismometers.
m/s² (meters per second squared): Measures acceleration sensitivity, important for strong-motion seismology.
g (gravity): Acceleration relative to Earth’s gravity (1 g = 9.80665 m/s²).
Gal: A unit of acceleration (1 Gal = 1 cm/s²), named after Galileo.
dyne/cm: A CGS unit of force per unit area, sometimes used in older seismological literature.
Why Conversion is Important
Different seismological studies and instruments report sensitivity in different units. Being able to convert between these units is essential for comparing measurements from different sources, integrating data from multiple instruments, and ensuring consistency in seismic analysis.

Earthquake Sensitivity Converter: A Must-Have Tool for Seismic Measurements
March 30, 2025 – Measuring earthquake sensitivity is crucial for seismologists, engineers, and researchers. Different instruments use different units, making conversions necessary. An Earthquake Sensitivity Converter simplifies this process. It helps convert between units like counts, nm/s, m/s², g, Gal, and dyne/cm quickly and accurately.
Why Sensitivity Conversion Matters
Seismic sensors detect ground motion. But they don’t all use the same measurement units. Some record in velocity (nm/s), others in acceleration (m/s² or g). Comparing data becomes difficult without conversion.
A sensitivity converter tool ensures consistency. It allows researchers to:
- Compare data from different instruments
- Standardize measurements for analysis
- Understand sensor performance better
Common Units in Seismic Sensitivity
- Counts – Digital output from seismometers. Represents raw sensor readings.
- Nanometers per second (nm/s) – Measures ground motion speed. Used in broadband seismometers.
- Meters per second squared (m/s²) – Measures acceleration. Important for strong-motion studies.
- Gravity (g) – 1 g = 9.80665 m/s². Used in engineering applications.
- Gal – 1 Gal = 1 cm/s². Named after Galileo.
- Dyne per cm (dyne/cm) – Older unit, still used in some research.
How an Earthquake Sensitivity Converter Works
The tool takes an input value and converts it between units. For example:
- Convert 100 counts to nm/s
- Change 0.5 g to m/s²
- Switch 200 Gal to dyne/cm
The conversion uses mathematical formulas. Each unit has a fixed relationship with others. The tool automates calculations, reducing errors.
