Short Notes Rapid Assessment of Damage Potential of Earthquakes in Taiwan from the Beginning of P Waves
نویسندگان
چکیده
To rapidly assess the potential for damage of an earthquake for purposes of earthquake early warning in Taiwan, we used the peak displacement and velocity amplitudes of the first 3 sec of the P wave. The vertical-component records, highpass filtered at 0.075 Hz, are used. We found that the peak initial-displacement amplitude (Pd) correlates well with the peak ground-motion displacement (PGD) and the peak ground-motion velocity (PGV) at the same site. When Pd 0.5 cm, the event is most likely damaging. If Pd is combined with the period parameter sc, determined in an earlier study, then sc Pd provides an even more robust parameter for assessing the potential for damage.

متن کاملCorrelations between Spectral Parameters of Earthquakes and Damage Intensity in Different RC Frames
In recent decades many researchers have studied on the damage assessment of structures after a seismic event. To assess the damage of structures under an earthquake, it is so important to study the correlations between earthquake parameters and damages of the structures. A lot of seismic parameters have been defined by researchers to characterize an earthquake. Spectral parameters of an earthqu...
متن کاملAssessment of DNA damage induced by butachlor on Cyprinuscarpio(L. 1758) using Single Cell Gel Electrophoresis
Butachlor (N-(butoxymethyl)-2-chloro-N-2, 6-diethylacetanillide) is widely used chloroacetanilide herbicide in Asian region, especially in the north of Iran. Several studies have been reported on toxicity of butachlor, but little information is accessible on DNA damaging potential. Thus, the present study was undertaken to investigate of DNA damage by butachlor in Cyprinuscarpio(Pisces: Cyprini...
متن کاملInfluence of Rigidity, Irregularity and Initial Stress on Shear Waves Propagation in Multilayered Media
The propagation of shear waves in an anisotropic fluid saturated porous layer over a prestressed semi-infinite homogeneous elastic half-space lying under an elastic homogeneous layer with irregularity present at the interface with rigid boundary has been studied. The rectangular irregularity has been taken in the half-space. The dispersion equation for shear waves is derived by using the pertur...
