sci.richter-energy-earthquake Calculator
Calculates seismic energy released by an earthquake from Richter magnitude: log E = 4.8 + 1.5M (energy in joules). Each magnitude unit represents a 31.6× energy increase — a M7.0 releases 31.6× more energy than M6.0.
Inputs
Magnitude
Reference formula or conversion factor shown for context.
Depth Km
Vertical extent downward, or thickness of a layer. For tanks: affects pressure at the base (P = ρgh).
Results
seismic energy (Joules)
Sample size or count used in the calculation.
TNT equivalent (kilotons)
Sample size or count used in the calculation.
estimated affected radius (km)
The computed radius -- half the diameter.
log E = 1.5M + 4.8
Reference formula or conversion factor shown for context.
10× magnitude increase
Sample size or count used in the calculation.
M6 vs M7
Reference formula or conversion factor shown for context.
