... (QF) to investigate the rupture processes of the 1970 Tonghai earthquake and potential future earthquakes. A nonplanar fault model including topography was adopted and embedded in heterogeneous media. Regional stress orientations with an interval of 5° were tested, and various fault geometry models...

...Hui-lan Zhou; Clarence R. Allen; Hiroo Kanamori Abstract The source processes of the 4 January 1970, Tonghai earthquake ( M s = 7.5) and the 6 February 1973, Luhuo earthquake ( M s = 7.5) in southwestern China were investigated using an inversion technique on the very complex body waves. The two...

Three earthquakes with magnitudes of M ≥ 7 have occurred on the Qujiang fault in recorded history, namely, the 1588 M 7.0 Qujiang earthquake, 1913 M 7.0 Eshan earthquake, and 1970 M 7.7 Tonghai earthquake [ 15 , 27 ]. Among them, the 1970 M 7.7 Tonghai earthquake produced a right...
