Scientific Methodology & The Gutenberg-Richter Law
Exponential Frequency Distribution (log N = a - bM)
In statistical seismology, the Gutenberg-Richter law dictates that for every unit increase in earthquake magnitude, the number of events decreases approximately tenfold (b ≈ 1.0). For every magnitude 6.0 shock, the Earth experiences ~10 magnitude 5.0 events, and ~100 magnitude 4.0 events.
By applying calibrated cutoffs (Top-5 for 24h, Top-7 for 7d, Top-10 for 30d, Top-15 for the year), our platform filters out high-frequency microseismicity while guaranteeing complete coverage of every notable and destructive event.
Radiated Energy Calculation (E = 10^(4.8 + 1.5M))
Seismic energy released into the Earth's crust is computed using the standard Gutenberg-Richter and Kanamori moment-energy formulation. A single M 7.0 shock releases ~31.6 times more energy than an M 6.0, and ~1,000 times more energy than an M 5.0.
TNT equivalence is benchmarked at 4.184 × 10⁹ Joules per metric ton of TNT explosive yield, providing a direct geophysical comparison for total crustal strain relief.
