Relocation of Local Earthquakes in North-Western Iran

Proceedings, 2012
Earthquake locations routinely determined by the Iranian Seismological Center (IRSC) show a diffuse image of seismicity in North-Western Iran. In order to obtain an enhanced picture of seismicity in this region, a large set of earthquakes recorded by 9 stations from 1996 through 2010 were relocated using the double-difference technique and an ...

On the relocation of earthquake clusters. A case history: The Arkansas earthquake swarm

Bulletin of the Seismological Society of America, 1989
AbstractA portable digital network (the PANDA array) of 40 three-component stations with an aperture of about 35 km was deployed for 4 months in the Arkansas swarm area in 1987. Only 12 swarm events occurred during the deployment, in contrast to the intense seismic activity that characterized this region in 1982 to 1984.

High precision relocation of earthquakes at Iliamna Volcano, Alaska

Journal of Volcanology and Geothermal Research, 2009
Abstract In August 1996, a period of elevated seismicity commenced beneath Iliamna Volcano, Alaska. This activity lasted until early 1997, consisted of over 3000 earthquakes, and was accompanied by elevated emissions of volcanic gases. No eruption occurred and seismicity returned to background levels where it has remained since.

Relocating the 2011 Tohoku-oki earthquakes (M 6.0–9.0)

Tectonophysics, 2013
Abstract The great Tohoku-oki earthquake (Mw 9.0) on 11 March 2011 was accompanied by nearly 100 large foreshocks and aftershocks (M ≥ 6.0) in the Northeast Japan forearc. In this study we relocated 77 of these large events using three different velocity models.

Relocation of the 2001 Earthquake Sequence in Aegion, Greece

Studia Geophysica et Geodaetica, 2004
The western part of the Corinth Gulf attracts attention because of its seismically active complex fault system and considerable seismic hazard. Close to the city of Aegion, damaged by the ML 6.2 earthquake of 1995, a sequence of small earthquakes occurred from February to May 2001. The sequence, comprising 171 events of ML 1.8 to 4.7, was recorded by a

Machine learning enhanced earthquake relocation

Seismic activity provides critical insights into subsurface processes such as tectonic movements, volcanic activity, and fluid migrations, with accurate earthquake locations being essential for enhancing our understanding of these seismic behaviors. However, seismic array geometry significantly influences earthquake location accuracy. Over the past two

High-resolution Earthquake Relocation in the New Madrid Seismic Zone

Seismological Research Letters, 2010
We present high-resolution earthquake locations for the New Madrid seismic zone (NMSZ) using the double-difference location method. The NMSZ consists of four major arms of seismicity centered in the central United States and is one of the few places of concentrated earthquake activity far from a major plate boundary.

Relocation of the 2012 M s6.6 Xinjiang Xinyuan earthquake sequence

Science China Earth Sciences, 2013
At 05:07 AM on June 30, 2012 (Beijing time), an Ms6.6 earthquake (hereafter referred to as Xinyuan earthquake) occurred at the junction of Xinyuan County, Ili Kazak Autonomous Prefecture and Hejing County, Bayinguoleng Mongol Autonomous Prefecture in Xinjiang Uygur Autonomous Region. The location of the main shock determined by China Earthquake Network

Relocation Pattern for Minority Villages Stricken by Wenchuan Earthquake

Applied Mechanics and Materials, 2013
After the Wenchuan earthquake, a number of minority villages face many difficulties in relocation due to their poor geographical location, backward economic development and poor inhabited environment. In this paper, successful pattern for relocation of minority villages are researched and explored through analysis, generalization and summation with the
