The MVP-LAI System
In August this year, CUG team led by Prof. CHEN Jiehong’s team from the School of Geophysics and Geomatics, together with Wuhan University, Zhejiang University, the Institute of Earthquake Forecasting of China Earthquake Administration, Sichuan Earthquake Bureau, and other 6 institutions, built the world’s first MVP-LAI (Monitoring of Vibrations and Perturbations in Lithosphere, Atmosphere and Ionosphere)System. The observation station is located in the suburbs of Leshan City of Sichuan Province, adjacent to the Tibetan Plateau in the west, the Yunnan-Guizhou Plateau in the south, the Sichuan Basin in the east, and the Longmenshan Fracture Zone in the north, and the surrounding geological activities are very favorable for geophysics as well as earthquakes and geohazards research.
It is the first “single-station and vertical” monitoring system in the world that realizes the joint observation of lithosphere, atmosphere, and ionosphere, and it is also the only monitoring system in the world today that can simultaneously monitor nearly 20 physical quantities such as ground vibration, air pressure, and ionospheric electron concentration. Thanks to it, humans are able to monitor cross-loop “vertical” disturbance transmission in real time.
The observation station of the MVP-LAI System has attracted the attention of international peers. The prestigious geophysicist K. Oyama called the system a “super station”. Since the start of construction in March 2020, Prof. CHEN’s team has analyzed and studied the data from the system in conjunction with observations from many research institutions across China, and has made several reliable forecasts of seismic events during internal tests. When the system is completed and put into operation, the research team expects to achieve more original results.
