Earthquake Magnitude and Energy Comparison
Magnitude-to-energy explorer
Earthquake Energy Comparator
Convert earthquake magnitude into estimated seismic energy and compare the exponential scale with familiar energy equivalents.
Listening to the Earth…
Why magnitude feels nonlinear
The estimate uses log₁₀(E joules) = 1.5M + 4.8. Each whole-number increase represents about 31.6 times more released energy. Comparisons describe energy only and do not predict damage, which depends on depth, distance, geology, buildings, and duration.

How the earthquake energy comparator works
Choose a time range, magnitude, location, or comparison value.
Tool Nova loads normalized earthquake data through a cached server route using official USGS public feeds.
Explore the map, timeline, distance, energy, or event details and open the USGS source when needed.
Frequently Asked Questions
Does this require an API key?
No. The USGS earthquake feeds and event service used by these tools do not require a visitor API key.
Can this replace an official emergency warning?
No. These tools visualize public earthquake records. Follow local emergency agencies and official tsunami warning centers for safety decisions.
