چکیده
|
The rupture processes of two sequential earthquakes have been inverted from teleseismic data. the first event released a total seismic moment of 7.9×1018 nm (mw 6.5) and the slip distribution shows three asperities,1.5 m at the shallow side,0.7 m at the right south-east deep side and 0.5 m at the northwest deep side. the second event had one asperity with 1.7 m slip and released a seismic moment of 7.5×1018 nm (mw 6.5). in both cases,maximum slip occurred above the hypocenter which was responsible for the surface displacement pattern. © 2014 published by itb journal publisher.
