Determining The Success of Strong Motion Records in Calculating P-Wave Moment Magnitude

Earthquake early warning systems have high importance and improving continuously using different analysing techniques. The system depends on calculating a magnitude in short time with as accuracy possible. Large earthquakes that tsunami potential occurred will be especially the Mediterranean Aegean Seas Turkey has settlements along these coastlines. In practice, weak-motion (velocity) records are generally used to determine magnitude, but seismic disadvantage: clipping problem around epicentre. Up now, there is not much work study of strong-motion (acceleration) calculate an earthquake accuracy. This focused P-wave moment body waves recorded at strong motion stations caused by possible source region earthquakes. For reason, we three larger than 6.0 Mw. difference between Global Centroid Moment Tensor (GCMT) about 0.2 m.u. which acceptable considering purpose.
