Fig. 14From: Temporal change in seismic wave attenuation using highly stable vibration sourcesThe temperature effect in the amplitude variation. The amplitude variation (blue and red dots) in major and minor axes of principal axes and fitting with variation in atmospheric temperature (green lines) are shown from 100Â h before the occurrence of WT and GY. The top two rows show the results for the 800-m sensors and the next two rows show those for the 1700-m sensors. The bottom row shows variation in atmospheric temperature. The left and right panels show the results for the WT and GY earthquakes, respectivelyBack to article page
