Source process of the twelve oct., 1992 Cairo earthquake

Broadband body waves recorded at 12 digital seismic stations worldwide are used to study the source process ofthe Oct.12, 1992 Cairo earthquake. To study the source process of this event the P and SH waveforms from IRIS data were inverted to double couple source using the method Kikuchi and Kanamori (1991)[1] in which the rupture is presented by discrete subevents with various mechanism. The best solution consists of only one event with a mechanism 270°/47°./-123°(strike./dip/slip), normal faulting mechanism with some strike slip component. This event took place at depth 22 km. The seismic moment of this event is 7.2 x 10 22 dyne.cm (M w =5.8) with a source duration of 4 seconds. The estimated fault length is about 11 km, the derived average dislocation (D) is 24.5 cm, the stress drop (Δσ) is 14.5 bar and the Orwan stress drop is 4.25 bar.
