Short-Period Multicomponent Strain System
Abstract
An examination of film recordings of strain noise, pressure fluctuations inside and outside of the strain vault, and wind velocity at WMO suggests that the long-period (LP) noise observed on the strain traces is caused by wind-pressure fluctuations that are coupled more strongly through the ground or by compression of the vault structure than through leakage of air through the vault enclosure. A study of the detection capability of the WMO LP strain seismographs shows that the environmental noise severely limits detection.
