Area of Science:

  • Geophysics
  • Seismology
  • Physics

Background:

  • The Gutenberg-Richter law describes earthquake frequency-magnitude distribution.
  • Understanding seismic energy release is crucial for earthquake prediction and hazard assessment.
  • Existing models often simplify the complex processes governing earthquake energy dynamics.

Purpose of the Study:

  • To derive the Gutenberg-Richter law from fundamental physical principles.
  • To establish a link between seismic diffusion processes and energy release.
  • To propose a relationship between critical exponents and stress release mechanisms.

Main Methods:

  • Postulating a diffusion process connecting kinetic energy in active zones to radiated energy.
  • Applying physical principles to model earthquake energy transfer.
  • Analyzing the relationship between the critical exponent and stress release.

Main Results:

  • The study successfully derives the earthquake distribution, consistent with the Gutenberg-Richter law.
  • A diffusion process model is established to explain energy transfer during seismic events.
  • A novel link is proposed between the critical exponent and the stress release associated with earthquakes.

Conclusions:

  • The proposed diffusion model provides a physical basis for the Gutenberg-Richter law.
  • The findings suggest that stress release dynamics are intrinsically linked to critical exponents in seismology.
  • This research offers new insights into the physics of earthquake energy distribution.
