The KUYUY Accelerograph and SIPA System: Towards Low-Cost, Real-Time Intelligent Seismic Monitoring in Peru.

Area of Science:

• Seismology and Earthquake Engineering
• Geophysical Instrumentation

Background:

• Accelerographs are crucial for measuring strong ground motion in earthquake engineering.
• Peru's national seismic network has limited spatial coverage and instrumentation, hindering seismic risk reduction.
• Existing networks are insufficient for detailed strong motion characterization.

Purpose of the Study:

• To introduce the KUYUY accelerograph, a low-cost, low-noise device with real-time telemetry.
• To enable real-time seismic monitoring and automated analysis for microzonation and damage assessment in Peru.
• To improve seismic risk reduction strategies through enhanced network capabilities.

Main Methods:

• Developed the KUYUY accelerograph featuring high-performance MEMS sensors and real-time telemetry.
• Integrated KUYUY with the Intelligent Automatic Processing System (SIPA) for automated analysis.
• Conducted validation through static gravity calibration, field comparisons, and initial deployment in Lima and Yurimaguas.

Main Results:

• The KUYUY accelerograph demonstrated linear response, temporal stability, and amplitude consistency.
• Performance differences compared to high-end instruments were within 5-10%.
• The device is interoperable with SIPA for real-time monitoring and automated signal analysis.

Conclusions:

• The KUYUY accelerograph is a viable, cost-effective solution for enhancing Peru's seismic monitoring network.
• The instrument's performance supports its use in seismic microzonation and rapid damage assessment.
• This development contributes significantly to improving seismic risk reduction policies in Peru.
