How this service works
Earthquake magnitude to radiated energy, seismic moment and TNT equivalent, with an optional comparison to a second magnitude.
Output
Returns the radiated seismic energy in Joules, seismic moment in Newton-metres, TNT equivalent in tons and kilotons, and Hiroshima bomb equivalents for the given magnitude. If a second magnitude is provided, also returns the energy ratio, amplitude ratio, and a comparative note between the two events. Includes the formulas used and a summary explanation.
Example use cases
Earthquake energy public explainer
“I'm writing about the 2011 Tōhoku earthquake which was magnitude 9.1 — can you tell me how much energy it released in joules, kilotons of TNT, and how many Hiroshima bombs that equals?”
Comparing two recent earthquake magnitudes
“There were two earthquakes today, one at magnitude 6.4 and one at magnitude 4.9 — how much more energy did the bigger one release, and what's the ratio between them?”
Education: TNT scale for classroom example
“For a school lesson on earthquakes, what is the TNT equivalent and Hiroshima equivalents for a magnitude 5.0 earthquake, and how does it compare to a magnitude 3.0?”

Endpoint
GEThttps://global-hazards.x402tookit.com/quake-energy?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to translate a raw earthquake magnitude number into physically meaningful units — joules, kilotons of TNT, or Hiroshima bomb equivalents — or when you want to quantitatively compare the energy difference between two magnitude values. Ideal for educational content, journalism, disaster risk communication, or any agent workflow that needs to explain earthquake severity in intuitive terms rather than the logarithmic magnitude scale.
Side effects
- Magnitude outside valid range (-2 to 10) returns a validation error
- compareTo magnitude outside valid range (-2 to 10) returns an error
- Missing required magnitude parameter returns a 400-level error
- Service degraded flag may be set if formula source data is unavailable
