Analysis of data quality from the emergency transportable seismic stations in Ningxia

This study examines the site selection, station type, construction mode, data quality, and environmental conditions of two transportable seismic stations operated by the Earthquake Agency of the Ningxia Hui Autonomous Region during emergency transportable seismic network drills in Northwest China in 2020 and 2021. The conclusions are as follows: The wind has a more significant impact on stations constructed on the ground than those buried underground, causing an increase in horizontal ground noise in the 1～20 Hz. In the windy area of Northwest China, under the same windproof and heat-retaining conditions, soil-based stations buried underground have better observation quality and lower ground noise levels than rock-based stations constructed on the ground.
