Coda-wave interferometry is a technique to detect small seismic velocity changes using phase changes in similar waveforms from repeating natural or artificial sources. Seismic interferometry is another technique for detecting seismic velocity changes from cross-correlation functions of ambient seismic noise. We simultaneously use these two techniques to clarify seismic velocity changes at Sakur...
The identification and classification of seismic signals is one of primary work that a volcano observatory must do, and this work should be done in a period of time as close as possible to the real time”. Each seismic event is related to a different source process, and its time and spatial distribution could be used as elements of an early warning system of volcanic eruption (see for example Ch...
Seismic modeling aids the geophysicists to have a better understanding of the subsurface image before the seismic acquisition, processing, and interpretation. In this regard, seismic survey modeling is employed to make a model close to the real structure and to obtain very realistic synthetic seismic data. The objective of this study is to analyze the resolution and illumination of the fault by...
