Multi-UAV system mapping earthquake surface ruptures

Project Overview

Earthquake surface ruptures provide critical insights into fault behavior, rupture mechanics, and seismic hazards. This project develops an innovative multi-UAV system capable of providing ultra-high-resolution (5 mm) mapping data over large areas, enabling rapid response mapping for earthquake events and detailed analysis of fault zone characteristics.

Research Objectives

  • Develop autonomous multi-UAV coordination algorithms for large-area mapping
  • Achieve millimeter-scale precision in surface rupture documentation
  • Create rapid response protocols for post-earthquake mapping
  • Quantify displacement patterns and rupture complexity
  • Advance understanding of fault zone architecture and mechanics

Technical Innovation

Our multi-UAV system represents a significant advancement in geological mapping technology:

  • Swarm Intelligence: Coordinated autonomous navigation and data collection
  • High-Resolution Imaging: Sub-centimeter pixel resolution across kilometers
  • Real-Time Processing: On-board data fusion and preliminary analysis
  • Adaptive Sampling: Dynamic mission planning based on terrain complexity
  • Multi-Sensor Integration: RGB, multispectral, and LiDAR capabilities

Study Areas

Southern San Andreas Fault - Salton Sea Region:

Our primary focus area includes the Southern San Andreas Fault near the Salton Sea, a seismically active region with high earthquake potential. This area provides an ideal testbed for our mapping technologies and offers opportunities to study fault zone evolution in real-time.

Additional Target Areas:

  • San Jacinto Fault Zone
  • Garlock Fault System
  • Eastern California Shear Zone
  • International collaboration sites (Turkey, Chile, New Zealand)

Rapid Response Capabilities

A key innovation of this project is the development of rapid response protocols that can be deployed within hours of a significant earthquake event:

  • Pre-positioned equipment at strategic locations
  • Automated mission planning based on preliminary rupture estimates
  • Real-time data transmission to emergency response centers
  • Integration with existing monitoring networks

Applications & Impact
