Employing Neuromorphic Computing Architectures for Real-Time Earthquake Prediction Systems

The Seismic Prediction Challenge: Why Conventional Systems Fall Short

Traditional earthquake prediction systems rely on seismographic data processed through conventional von Neumann computing architectures. While these systems have provided valuable insights, they face three critical limitations:

• Latency bottlenecks: The separation of memory and processing units creates inherent delays in data analysis
• Energy inefficiency: High-power requirements limit deployment in remote seismic zones
• Pattern recognition limitations: Conventional algorithms struggle with the nonlinear dynamics of precursory seismic signals
