📏 Fault Geometry
Fault Length (km): 10.0
Fault Width (km): 8.0
Rupture Area
80 km²
Aspect Ratio
1.25
📐 Displacement & Material
Average Slip (m): 1.0

🧮 Calculated Results
2.4 × 10¹⁶
N·m (Seismic Moment)
M 6.2
Moment Magnitude (Mw)
M₀ = μ × A × D
M₀ = Seismic Moment
μ = Rigidity (rock stiffness)
A = Rupture Area
D = Average Slip
💡 Moment Analogy
🔧
Seismic moment is like the "turning force" when using a wrench. Larger force (μ), longer wrench (A), and more rotation (D) create more moment!
