Abstract

The relationship between volcanic activity and the occurrence of non-DC earthquakes with dominant vertical tension or pressure is known as vertical compensated-linear-vector-dipole. This study aims to identify whether the earthquake that occurred in Southwest Keerom, Papua, around Jayawijaya Mountains on July 17th, 2014 was a volcanic earthquake or tectonic earthquake based on the results of the CMT solution. The results of this study also provide reinforcement of the previous studies result both in terms of magnitude and the epicenter depth. For the magnitude, not all of the Mw volcanic earthquakes are less than 3, but it proved that there were volcanic earthquakes that had a magnitude of Mw 4.3 to 5.8. The CLVD vertical earthquake that was identified in this study was classified as a shallow earthquake. © Published under licence by IOP Publishing Ltd.
