The M•,=7.4 Izmit, Turkey earthquake triggered widespread regional seismicity in Greece over a study region extending from 400 km to nearly 1000 km away from the epicenter. Small events began immediately after the passage of the mainshock surface waves suggesting that the transient stresses of the seismic waves were the trigger. The increase in cataloged earthquakes in ordinary continental crus...

Implementing and exploring innovative approaches to seismicity analysis and earthquake statistics has been the focus of my research for the past five years. The comprehensive seismicity analysis software that I have developed, ZMAP, is distributed by IASPEI and now in use in more than 30 research institutes worldwide. This resulted in multiple opportunities for collaborative research projects. ...

Most of the seismicity in the Los Angeles Basin (LA Basin) occurs at depth below the sediments and is caused by transpressional tectonics related to the big bend in the San Andreas fault. However, some of the seismicity could be associated with fluid extraction or injection in oil fields that have been in production for almost a century and cover ~ 17% of the basin. In a recent study, first the...

Data from 10,126 earthquakes that occurred in the southern California region between 1934 and 1963 have been synthesized in the attempt to understand better their relationship to regional geologic structure, which is here dominated by a system of faults related mainly to the San Andreas system. Most of these faults have been considered "active" from physiographic evidence, but both geologic and...

Seismicity and distribution of earthquakes can provide active fault structural information on the crust at a regional scale. The morphology faults be derived from epicentral micro-earthquakes. In this study, we combined both relocated earthquake catalogue related preliminary geophysical for 3D modeling in Xichang area, Sichuan province, China. deep crustal structure were automatically extracted...

SUMMARY A series of studies were commissioned by Cuadrilla Resources Ltd to examine the possible relationship between hydraulic fracture operations at the Preese Hall well, near Blackpool, and a number of earthquakes which occurred in April and May 2011, the largest of which had a magnitude of 2.3 M L. The reports from these studies conclude that the earthquake activity was caused by direct flu...

The 1999 Izmit earthquake (17/08/1999, Mw=7.4) was one of the largest earthquakes to occur in northwestern Turkey during the past 100 years. This earthquake occurred along the Izmit-Sapanca fault within the Northern Anatolian Fault Zone. Variations in the generalized fractal dimensions (Dq) of clustering in time and space, the Gutenberg-Richter b value, and earthquake frequency (N) are evaluate...
