The scatter of time-delays in shear-wave splitting above small earthquakes [PDF]

open access: yes, 2004
Measurements of time-delays in seismic shear-wave splitting above small earthquakes typically display a scatter of often as much as ±80 per cent about the mean. Changes in the average time-delay appear to be related to changes of stress, but applications
