Quick Answer

The Earthquake Magnitude Comparator is a free, no-sign-up utility that instantly compares earthquake sizes by revealing how much stronger one is than another—a magnitude 6 releases about 31.7 times more energy than a magnitude 5.[2][5] Use it to convert magnitudes into intuitive equivalents like 30,000 tons of TNT for a magnitude 6, helping residents, responders, and educators grasp logarithmic scales effortlessly.[2]

Why You Need This

Earthquake magnitudes are logarithmic, meaning each whole number increase amplifies wave amplitude by 10 times and energy by 31.7 times—a common source of public confusion amid 500,000 annual quakes, 100,000 felt by humans, and 20+ causing major damage.[1][2][5][6] For instance, a magnitude 6 ML equals 30,000 tons of TNT (like a 30-kiloton nuke), dwarfing a magnitude 5's 1,000 tons.[2]

Multiple scales exacerbate issues: Richter (ML) suits local events up to 600 km but saturates for giants, while moment magnitude (Mw) excels for all sizes, handling the record Mw 9.5 in 1960 Chile without limits.[1][3][4] Seismic zones like California, Japan, and Turkey demand this for risk assessment; emergency planners link it to peak ground acceleration (PGA), educators debunk myths, and journalists clarify magnitude vs. intensity.[1][3][7]

How It Works

Enter two magnitudes (e.g., 5.8 vs. 7.1) into this free online tool—it outputs relative strength, energy ratios, and equivalents like atomic bombs or eruptions, prioritizing Mw for accuracy on large events.[1][3] No downloads or accounts needed; results highlight 32x energy jumps per unit for quick insights.[3][4]

Tips for Best Results

  • Choose Mw for global or large quakes (>8), as scales like Ms saturate; verify via USGS.[1][2][4][6]
  • Compare energy (31.7x) separately from amplitude (10x) using verified data—cross-check ML vs. Mw for mediums (4.5-7.5).[5]
  • Pair with intensity maps and PGA for damage predictions; avoid equating magnitude directly to local impact.[3][5][7]
  • Share visuals for education, like 1906 San Francisco's Mw 7.9, to inform preparedness in high-risk areas.[1]
