Stress Release Mechanism

📊 Public Perception vs. Scientific Reality

Public expectation: Aftershocks should quickly diminish and stop within days.

Scientific reality: Omori's Law shows power-law decay - significant aftershocks can occur weeks to years later, with the "late large aftershock" phenomenon being a major public safety concern.

🔬 Current Interpretation

Parameters set to typical values. K controls the total number of aftershocks, c smooths the initial rate peak, and p determines how quickly the rate decays over time.
