in northwest China's Gansu Province, one of the country's four major cave complexes.
The system aims to enhance earthquake early warning capabilities for the 1600-year-old UNESCO World Heritage Site,
historically damaged by earthquakes while providing a model
for safeguarding other grottoes nationwide.
Zhou Weidong, a senior engineer at the Gansu Earthquake Agency,
said that the monitoring network integrates over 200 seismic stations within a 100-kilometer radius of the grottoes and six stations on the cliff.
The system enables real-time tracking of earthquake activity and vibrations through regular data transmission and 3D modeling.
offering scientific support for customized anti-seismic strategies.
Zhou noted that the data will provide critical insights for future preservation and reinforcement efforts.
In daily conservation work,
Engineers also utilize nodal seismometers to analyze vibration patterns across the walkways and cliff.
Advanced damage identification technology helps identify structural issues with millimeter-level precision.
guiding timely repairs.
The Maiji Shan Grottoes were inscribed on the World Heritage List in 2014.
The site features 221 caves carved into a cliff linked by 1.5 kilometers of aerial walkways.
with the highest pathway reaching over 70 meters above ground.
