The very large earthquake doublet comprised a Mw 7.6 initial shock that had a maximum Mercalli intensity of VI (Strong) and a second event measuring Mw  7.4 and a maximum Mercalli intensity of VII (Very strong). The events took place less than three hours apart to the east-northeast of Sorong on the Bird's Head Peninsula and left at least four people dead and dozens injured.

An official of World Vision International, a humanitarian aid organization, said ten buildings had been destroyed, including several hotels and the house of a government official. Officials said three people, who had been staying at the Mutiara hotel in the city of Manokwari, were pulled alive from the rubble and taken to a hospital. Two hotels collapsed in the quake.
