Broadband analysis of the 21 September, 1993 Klamath Falls Earthquake Sequence

The source characteristics of the Klamath Falls earthquake sequence were estimated from broadband seismograms recorded by the Berkeley Digital Seismic Network (BDSN), TERRAscope, and western United States IRIS stations. Solutions were obtained for events ranging in size from Mw 3.8 to Mw 6.0. An empirical Green's function inverse approach was used to estimate kinematic source parameters of the two Mw 6.0 mainshocks. Both events were found to have ruptured northwest on adjacent segments of the Lake of the Woods system of normal faults. The two main-shocks abut where there is a pronounced 10° to 20° clockwise rotation of strike which may have initially acted as a barrier to a through-going Mw 6.2 event.
