Body wave attenuation characteristics in the crust of Alborz region and North Central Iran

Abstract Attenuation of P and S waves has been investigated in Alborz and north central part of Iran using the data recorded by two permanent and one temporary networks during October 20, 2009, to December 22, 2010. The dataset consists of 14,000 waveforms from 380 local earthquakes (2 < ML <...

520			\|a Abstract Attenuation of P and S waves has been investigated in Alborz and north central part of Iran using the data recorded by two permanent and one temporary networks during October 20, 2009, to December 22, 2010. The dataset consists of 14,000 waveforms from 380 local earthquakes (2 < ML < 5.6). The extended coda normalization method (CNM) was used to estimate quality factor of P (QP) and S waves (QS) at seven frequency bands (0.375, 0.75, 1.5, 3, 6, 12, 24 Hz). The QP and QS values have been estimated at lapse times from 40 to 100 s. It has been observed that the estimated values of QP and QS are time independent; therefore, the mean values of QP and QS at different lapse times have been considered. The frequency dependence of quality factor was determined by using a power-law relationship. The frequency-dependent relationship for QP was estimated in the form of (62 ± 7)f(1.03 ± 0.07) and (48 ± 5)f(0.95 ± 0.07) in Alborz region and North Central Iran, respectively. These relations for QS for Alborz region and North Central Iran have estimated as (83 ± 8)f(0.99 ± 0.07) and (68 ± 5)f(0.96 ± 0.05), respectively. The observed low Q values could be the results of thermoelastic effects and/or existing fracture. The estimated frequency-dependent relationships are comparable with tectonically active regions.

The dataset consists of 14,000 waveforms from 380 local earthquakes (2 < ML < 5.6). The extended coda normalization method (CNM) was used to estimate quality factor of P (QP) and S waves (QS) at seven frequency bands (0.375, 0.75, 1.5, 3, 6, 12, 24 Hz). The QP and QS values have been estimated at lapse times from 40 to 100 s. It has been observed that the estimated values of QP and QS are time independent; therefore, the mean values of QP and QS at different lapse times have been considered. The frequency dependence of quality factor was determined by using a power-law relationship. The frequency-dependent relationship for QP was estimated in the form of (62 ± 7)f(1.03 ± 0.07) and (48 ± 5)f(0.95 ± 0.07) in Alborz region and North Central Iran, respectively. These relations for QS for Alborz region and North Central Iran have estimated as (83 ± 8)f(0.99 ± 0.07) and (68 ± 5)f(0.96 ± 0.05), respectively. The observed low Q values could be the results of thermoelastic effects and/or existing fracture. The estimated frequency-dependent relationships are comparable with tectonically active regions.

The dataset consists of 14,000 waveforms from 380 local earthquakes (2 < ML < 5.6). The extended coda normalization method (CNM) was used to estimate quality factor of P (QP) and S waves (QS) at seven frequency bands (0.375, 0.75, 1.5, 3, 6, 12, 24 Hz). The QP and QS values have been estimated at lapse times from 40 to 100 s. It has been observed that the estimated values of QP and QS are time independent; therefore, the mean values of QP and QS at different lapse times have been considered. The frequency dependence of quality factor was determined by using a power-law relationship. The frequency-dependent relationship for QP was estimated in the form of (62 ± 7)f(1.03 ± 0.07) and (48 ± 5)f(0.95 ± 0.07) in Alborz region and North Central Iran, respectively. These relations for QS for Alborz region and North Central Iran have estimated as (83 ± 8)f(0.99 ± 0.07) and (68 ± 5)f(0.96 ± 0.05), respectively. The observed low Q values could be the results of thermoelastic effects and/or existing fracture. The estimated frequency-dependent relationships are comparable with tectonically active regions.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Seismic attenuation</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Body waves</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Wave propagation</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Coda normalization method (CNM)</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Hamzehloo, H.</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Journal of seismology</subfield><subfield code="d">Dordrecht [u.a.] : Springer Science + Business Media B.V, 1997</subfield><subfield code="g">21(2016), 4 vom: 20.

abstract	Abstract Attenuation of P and S waves has been investigated in Alborz and north central part of Iran using the data recorded by two permanent and one temporary networks during October 20, 2009, to December 22, 2010. The dataset consists of 14,000 waveforms from 380 local earthquakes (2 < ML < 5.6). The extended coda normalization method (CNM) was used to estimate quality factor of P (QP) and S waves (QS) at seven frequency bands (0.375, 0.75, 1.5, 3, 6, 12, 24 Hz). The QP and QS values have been estimated at lapse times from 40 to 100 s. It has been observed that the estimated values of QP and QS are time independent; therefore, the mean values of QP and QS at different lapse times have been considered. The frequency dependence of quality factor was determined by using a power-law relationship. The frequency-dependent relationship for QP was estimated in the form of (62 ± 7)f(1.03 ± 0.07) and (48 ± 5)f(0.95 ± 0.07) in Alborz region and North Central Iran, respectively. These relations for QS for Alborz region and North Central Iran have estimated as (83 ± 8)f(0.99 ± 0.07) and (68 ± 5)f(0.96 ± 0.05), respectively. The observed low Q values could be the results of thermoelastic effects and/or existing fracture. The estimated frequency-dependent relationships are comparable with tectonically active regions.
