Abstract:

The relative amplitude method of determining earthquake source orientations is applied to short period teleseismic array observations of the 1976 Uzbekistan earthquake sequence. Many of these events are shown to be consistent with a double couple source, and the method provides well determined orientations for most events with magnitude mb between 4.0 and 5.6. Author
