The depth of the earthquake was 594 kilometers. “The quake was caused by activities along Indo-Australia subduction zone into the Eurasian plate north of Madura.” An analysis based on quake source mechanism shows that the quake was caused by normal faulting.
BMKG’s shakemap indicates that weak tremors may be felt in Bangkalan, Gresik, Tuban, Surabaya, Sidoarjo and Situbondo at the intensity I of the BMKG scale or II MMI. “The quake did not have the potential to cause a tsunami,” Daryono said.
As of 7:30 am, BMKG observed that aftershocks are unlikely.
