Combination of double couple and non-double couple events during the Van, Turkey, 2011 earthquake sequence

► Mw = 6.0, 2011/10/23:20:45 event was triggered by the Mw = 7.1, 2011/10/23:10:41 event. ► Deviatoric moment tensor inversion on both aftershocks represents large CLVD. ► Suggestions for mechanism CLVD: crustal rheology and volcanic activities. ► Most probably CLVD is resulted from magma/water-magma (fluid) injection to this environment.
