A NEW ASSESSMENT OF ERRORS FROM DIGITIZATION AND BASE LINE CORRECTIONS OF STRONG-MOTION ACCELEROGRAMS
Statistical analysis of strong-motion records of the 1966 Parkfield earthquake
and the 1952 Taft earthquake indicates that the usable limit of long period of
velocity and displacement, calculated by integration ...
PARKFIELD, CALIFORNIA, EARTHQUAKE OF JUNE 1966:INTERPRETATION OF THE STRONG MOTION RECORDS
A detailed seismological interpretation of the strong motion records was attempted for the 1966 Parkfield earthquake, California. Velocity and displacement traced integrated from the corresponding recorded accelerograms ...
Attenuation Relations for Peak and Response Spectra of Horizontal Acceleration from Strong-motion Records for the Main Seismic Zones of the Iranian Plateau
Attenuation relationships for the peak horizontal ground acceleration (PHA)
and for the response spectra of the horizontal ground acceleration (RSHA) for
the main seismic zones of the Iranian plateau (i.e., ...
Local Magnitude Scale in Khorasan Region of Iran Based on Broad-band Seismograms
The province of Khorasan, extending from 30.0N to 39.0N and from 55.0E to60.0E, is the region with the highest seismic activity in the Iranian plateau. We employed broad-band seismograms which were recorded by the Khorasan ...
SOURCE GEOMETRY AND MECHANISM OF 1978 TABS, IRAN, EARTHQUAKE FROM WELL LOCATED AFTRERSHOCK
Aftershock of the September 16, 1978 Tabas earthquake located from close-in observations madeduring a four-week fielding of temporary stations have been analyzed for the purpose of delineating detailed source geometry of ...
A GENERALIZED STRONG-MOTION ACCELEROGRAM BASED ON SPECTRAL MAXIMIZATION FROM TWO HORIZONTAL COMPONENTS
A new form of strong-motion accelerogram ("spectrally maximized record"
or "SMR") and its associated generalized spectrum are proposed for earthquake
engineering use. Parameters (e.g., spectral, duration, ...
SEISMICITY OF THE IRANIAN PLATEAU AND BORDERING REGIONS
Seismicity of the Iranian Plateau and bordering regions during the past 22½ yr
from 1 July 1957 through December 1979 is investigated in four successive time
intervals by analyzing close to 4000 earthquakes ...
مشخصه های تنش زمین ساختی در فلات ایران با استفاده از تعیین ساز و کار کانونی زمین لرزه های ثبت شده
The paper presents a study of focal mechanism of earthquakes and stress indicators for Iranian plateau and surrounding regions. All recorded earthquakes with magnitude of 4.5 and higher, occurred from 1964 to 2000, have ...
Earhquake-Fault hazard Investigations in the Mashhad-Neyshabur Region
In this paper seismotectonic characteristics(earthquake-fault hazarda) of the Mashhad-Neyshabur fault near Neyshabur and absence of large earthquakes in 20th century in this region is a major problem. Seisrisk II computer ...
Stochastic Finite-Fault Modeling of Strong Ground Motions from the 26 December 2003 Bam, Iran, Earthquake
On 26 December 2003, a destructive earthquake with an estimated
Mw 6.5 occurred in southeastern Iran, causing extensive destruction in the city of
Bam and its vicinity. The source of this shock was reported ...
