Journal of Geophysical Research, 2007 We have developed a double‐difference algorithm to relocate earthquakes recorded at global seismic networks, using differential arrival times for first and later arriving regional and global phases to invert for the vectors connecting the hypocenters.

Hypocenters relocation using double-difference method around Molucca Collision Zone
AIP Conference Proceedings, 2017Eastern Indonesia is situated in a very complicated tectonic settings due to the converging of three major plates. Those plates do not have a clear boundary between each other. The boundary zone is covered by many microplates which converging or subducting to each other or create a large dimension of transform fault.

Towards Real-Time Double-Difference Hypocenter Relocation of Natural and Induced Seismicity
2020<p>In order to assess the fault-geometry and the spatio-temporal evolution of natural and induced seismicity, high-precision (relative) micro-seismic hypocenter locations are key information. From such precise relative hypocenter locations, we can infer e.g.

Hypocenters Relocation Using Double Difference Method Around Mount Agung, Bali
Proceedings (EAGE), 2018Summary After a long sleep for 54 years, now we are surprised by the presence of seismic activities of Mount Agung that has recorded since September 2017. We can’t prevent the eruption, however we can observe magma movement in the body of volcanos. Hypocenters distribution is an important information that can be used to reveal the magma movement in the

IOP Conference Series: Earth and Environmental Science, 2019 AbstractThe Sumatran fault zone has a high seismicity and seismic hazard threat levels due to this fracture through densely populated areas. The fault zone of Sumatera has 19 main segments which each segment has the possibility to generate a strong earthquake.

Relocation of volcano-tectonic earthquake hypocenter at Mt. Sinabung using double difference method
AIP Conference Proceedings, 2017Sinabung is one of the active volcanoes in Indonesia that located in Karo, North Sumatra. Before the eruption in August 2010, this mountain is type-B volcano and then it change to type A volcano. Since the eruption in 2010, volcanic activity still continue and hasn’t show any signs of stopping yet.

Abstract A large set of seismic events recorded along the southern flank of the central Alborz in the Tehran, Iran, region during 1996–2008 were relocated using the double-difference technique and an appropriate velocity model. The relocated hypocentral locations improve significantly in comparison with those routinely determined by the Iranian ...

The double-difference earthquake relocation algorithm (DD algorithm) has been applied to the accurate relocation of 10057 earthquakes in the central-western China (21°-36°N, 98°-112E°) during the period of 1992-1999. In total, 79706 readings for P waves and 72169 readings for S waves were used in the relocation, and the source parameters of 6496 events
