TEMPO.CO, Bandung - Earthquake struck two regions in Papua on Wednesday, October 12, 2016. Chief of Earthquake and Tsunami Mitigation Department at the Meteorology, Climatology, and Geophysics Daryono informed that both quakes at Sorong and Bintuni Bay will not cause a tsunami.
An analysis conducted by the BMKG shows that the first earthquake that shook Sorong happened at 01.46 Western Indonesia Time with the magnitude of 4.2. The epicenter was at the coordinate of 0.76 degrees South Latitude and 131.27 degrees East Longitude at the depth of 5 kilometers deep.
The second earthquake that shook Bintuni Bay occurred on 06.29 Western Indonesia Time, with the magnitude of 5.4 at the coordinate of 2.26 degrees South Latitude and 133.86 degrees East Longitude at the depth of 10 kilometers.
The II intensity scale earthquakes have shook Kalawas, Papermaranda, Melih, Selebar, and Makbon.
The range of the earthquake at Bintuni Bay affected a wider area, which includes Bisaisona, Sinyori, Mangkoi, Randepandai, Mondan, and Robobusai.
Based on the depth of the hypocenter, both of the earthquakes can be categorized as a shallow earthquake that was triggered by a 'fault' activity. “Both the earthquakes don’t seem to be related because both sources were far apart from each other,” Daryono said.
