The earthquake was triggered by a thrust fault in the Anjak Mamberamo zone at a depth of 50 kilometers.
"It is a shallow type of earthquake due to thrust fault activity in the Anjak Mamberamo zone," the Head of the Earthquake and Tsunami Center of the agency Daryono said here on Sunday.
Daryono also updated information on the earthquake, which initially had a magnitude of 6.5 in the northeastern area of Kobagma, Papua Pegunungan, to a magnitude of 6.4 in the Bonggo area, Sarmi District, Papua.
"The epicenter of the earthquake is located at 2.96 south latitude and 139.42 east longitude or precisely located on land at a distance of one kilometer south of Bonggo, Sarmi, Papua, with an updated parameter of magnitude 6.4," he explained.
He explained it affected and was felt in the Jayapura District area with an intensity scale of III-IV MMI (modified mercalli intensity), meaning that if the earthquake occurred during the day, it would be felt by many people in the house.
