| Abstract: | With the development of the social economy in China, the damage to the observation environment at seismic stations is becoming more and more serious. The environmental noise of Lanzhou Seismic Array is investigated, and the linear distance between the array and the major interference sources marked internationally is quantitatively analyzed and provided to fully understand the influence degree of each interference source on the seismic array. The results show that the environmental noise level of Lanzhou Seismic Array is still up to level Ⅰ, which meets the observation conditions of an array. |
