LANZHOU, May 14 (Xinhua) — The construction of a large-scale seismic monitoring network was completed Tuesday at Maijishan Grottoes in northwest China’s Gansu Province, one of the country’s four major cave temples, a leading advanced system among the country’s cave temples.
The network aims to enhance earthquake early warning capabilities at the 1,600-year-old UNESCO World Heritage site, which has historically suffered from earthquakes, while also serving as a model for the protection of other grottoes across the country.
According to Zhou Weidong, a senior engineer with the Gansu Provincial Seismological Administration, the monitoring network includes more than 200 seismic stations within a 100-kilometer radius of the grottoes and six stations on the cliff.
According to the agency, the system allows for real-time monitoring of seismic activity and vibrations through regular data transmission and 3D modeling, offering scientific support for the development of individual anti-seismic strategies.
“The data obtained provides important information for future work on preserving and strengthening the grottoes,” Zhou Weidong noted.
In their daily work to preserve the grottoes, engineers also use nodal seismometers to analyze vibration patterns on the walkways and rocks in the cave-temple complex. Advanced damage identification technology helps identify structural problems with millimeter accuracy, providing technical guidance for repair work.
The Maijishan Grottoes and Temples complex was listed as a UNESCO World Heritage Site in 2014. The complex contains 221 caves carved into the rock, connected by 1.5-kilometer-long aerial passages, the highest of which is more than 70 meters above the ground. -0-
