Abstract Since the 1985 M 8.0 central Chile earthquake, national strong‐motion seismic
networks have recorded ten megathrust earthquakes with magnitudes greater than M 7.5 at …

Accurately ascertaining the S-wave arrival times of microseismic signals is crucial for
improving the accuracy with which microseismic events can be located. However, the first …

Determining P and S wave arrival times while minimizing noise is a major problem in
seismic signal analysis. Precise determination of earthquake onset arrival timing …

Identification of P-and S-phase arrivals is the primary work in microseismic monitoring. In
this study, a new multi-step AIC algorithm is proposed. This algorithm consists of P-and S …

At the moment, the analysis of the named complex systems is based mainly on the study of
the properties of the signals that is possible to measure. In general, these signals are …

Measuring physical characteristics of the earth using direct or indirect methods can be useful
to achieve knowledge about geological structures. This could help in solving many …

It is difficult to identify P-and S-waves arrival time from the recorded seismograms with low
Signal–to–Noise Ratio (SNR) because the onset is not always clearly observed. However …

In Seismology, exact recognition of arrival times of seismic wave has been a key challenge
for a geologist. The arrival time of body waves provides significant information about the …

Parametric filters are widely used to determine arrival time of P wave. The disadvantage of
its method is phase shifting occurred on filtered seismic signal. Consequently, an arrival time …

Due to the large number of influencing factors, it is difficult to predict the earthquake which is
a natural disaster. Researchers are working intensively on earthquake prediction. Loss of …
