Relocation of the Hypocenter of an Earthquake with the Double Difference Method in the Regional Study Area of Yogyakarta

JURNAL GEOCELEBES, 2023
The relocation of the earthquake hypocentre is necessary in order to determine the position of the earthquake centre with higher accuracy. An accurate hypocentre position is important for earthquake-prone areas mapping, seismicity analysis, and fault zone identification. The double difference algorithm technique using the hypoDD program can be used for

Double-Difference Seismic Event Relocation: A Study of the Applications and Limitations of the Relocation Problem

Earthquake relocation provides refined earthquake catalogs based on additional considerations or data beyond the initial earthquake location estimates. Double-difference relocation, in particular, utilizes the assumption that ray paths in close proximity to one another will pass through a similar earth velocity structure.

Double-difference relocations of the 2004 off the Kii peninsula earthquakes [PDF]

Earth, Planets and Space, 2005
Abstract Two large earthquakes (Mw7.3 and Mw7.5) occurred off-shore of the Kii peninsula (Japan) on 5th September 2004. The insufficient station coverage in the area where the large events and their aftershocks occurred led to significant uncertainty regarding their depth location.

Relocation of Earthquake Hypocenter Using Double-Difference Method in Western Part of Sumatera

Journal of Physics: Conference Series, 2023
Abstract The western part of Sumatra has a fairly complex tectonic setting where there is a convergent meeting between the Indo-Australian plate and the Eurasian plate. These plates form a subduction zone and also the Sumatran Fault. The subduction zone and the Sumatran Fault cause many earthquakes in western Sumatra.

Investigation of the Thiva 2020–2021 Earthquake Sequence Using Seismological Data and Space Techniques

Applied Sciences, 2022
We investigate an earthquake sequence involving an Mw = 4.6 mainshock on 2 December 2020, followed by a seismic swarm in July–October 2021 near Thiva, Central Greece, to identify the activated structures and understand its triggering mechanisms. For this

Seismicity Structure of the Northern Chile Forearc From >100,000 Double‐Difference Relocated Hypocenters [PDF]

Journal of Geophysical Research: Solid Earth, 2018
AbstractIn this study, we present high‐resolution seismicity images of the northern Chile subduction zone forearc. We used 8 years of continuous seismic waveform data from the Integrated Plate Boundary Observatory Chile network and auxiliary stations to produce an extensive earthquake catalog containing 101,601 double‐difference relocated earthquake ...

Crustal structure and the seismogenic environment in Yunnan imaged by double-difference tomography

Frontiers in Earth Science, 2023
The large-scale faulting and earthquake activities that developed extensively in the Yunnan area are associated with the collision of India and Eurasia. The fine crustal structure can provide a better understanding of the crustal deformation, seismogenic
