Passive Source Detection Technology Based on Short-Period Dense Seismic Array

Description: 

In the past decade, passive source detection technology based on short period dense array has increasingly become a domestic and international significant tool in the field of deep structure exploration. Compared with the traditional broadband seismic method, this technology has the advantages of high resolution, efficiency, cost saving, and minimal environmental impact. Despite the low-frequency signals being too weak to detect the deep structures within the lithospheric mantle, the dense station distribution allows imaging of detailed structures within Earth’s crust. Furthermore, taking advantage of the dense ray crossing coverage from different directions beneath the array, a stable image of crust-mantle structures can be imaged by inversion and stack migration. Therefore, the short period dense array detection technology has been widely used in different fields, such as imaging of deep velocity and interface structure, mineral resources exploration, volcanic activity monitoring, microseismic high-precision Locations, and geometry and kinematic characteristics: key aspects of seismogenic faults. With the research progress of short period dense array in the field of imaging study on crustal structures and microseismic location monitoring. Looking into the future and guided by scientific questions, joint inversion and imaging could be carried out using a variety of geophysical data such as natural earthquake, ambient noise, gravity, InSAR, GPS and magnetotelluric measurements to acquire the multi-attribute characteristics of the interested targets, and this method is increasingly developing to an effective way to reduce the non uniqueness of solutions and reveal the real state of geological bodies. The rapid development of the detection methods in this area is expected to greatly promote the research of seismology and geodynamics, and has a broad application prospect in the fields of deep structure imaging and mineral resources exploration. As the world's leading manufacturer of short-period seismic equipment, SmartSolo provides highly reliable, consistent, and cost-effective short-period seismometer solutions.
