Researchers of the world’s first interdisciplinary research-based and integration-based seismic activity monitoring system that can simultaneously monitor approximately 20 physical parameters related to the lithosphere, atmosphere and ionosphere, are committed to providing strong support data for geoscience research, including earthquake prediction.
Located in the forests of Leshan city, southwest China’s Sichuan Province, the Lithosphere, Atmosphere and Ionosphere Vibration and Disturbance Monitoring System Project (MVP-LAI ) led by the Wuhan University of Geosciences of China, has recently been put into operation and has started to send real-time data back to the data center for analysis.
“Most current surveillance systems only focus on a single sphere or a single physical parameter, which cannot effectively reflect a full abnormal course and mechanism, while the new system can improve current mechanisms by comparing multiples. abnormal physical parameters to integrate or test known anomalies, “Chen Jiehong, a professor at the Institute of Geophysics and Geomatics at the Chinese University of Geosciences in Wuhan, who led the project told the Global Times on Wednesday.
Through data analysis in cooperation with the Institute of Earthquake Forecasting, China Earthquake Administration, Chen’s research team successfully identified the pre-earthquake vibrations and standing wave effects of two earthquakes in May. , the 7.4 magnitude earthquake in Maduo County in northwest China’s Qinghai Province. and a 6.4 magnitude earthquake in Yangbi Yi Autonomous County in southwest China’s Yunnan Province.
According to Chen, the monitoring system is the world’s first interdisciplinary geoscience integration research system that will provide strong data support for geoscience research in the years to come.
Occupying an area of 225 square meters, the system includes at least 14 monitoring facilities such as a wind profiler, a large facility for observing atmospheric fluctuations and a sonar detection system that measures temperatures in a range of 1,000 meters.
The system’s location in Leshan is in the Sichuan Basin which is surrounded by the Qinghai-Tibet Plateau and the mountains. “We mainly observe vertical disturbances or fluctuations. The vertical distance between the Qinghai-Tibet Plateau and the Sichuan Basin is over 3,000 meters, which allows us to more easily monitor vertical disturbances or fluctuations,” Chen said.
According to Chen, the system has adopted a whole new technology whereby observational data of the lithosphere, atmosphere and ionosphere are jointly monitored by a single system for the first time in the world. “Since a variety of instruments are involved, we have to be careful of interference between the instruments,” Chen said.
The system’s vertical observation range can monitor soil vibration, topographic variation, geomagnetic field, groundwater up to 5 meters below the ground or monitor atmospheric pressure, atmospheric wind field, atmospheric electric field or other changing data of physical parameters up to 350 kilometers above the earth.
Through precise calculations of this data and fluctuations in the data, researchers can predict earthquakes as well as other severe space weather phenomena such as thunderstorms and squalls based on analysis combined with obtained data. from other vantage points.
