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 the 1978 earthquake. Spatial...

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 program used for seismic...

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 were found most valuable...

The 1978 Tabas, Iran, earthquake (Ms -- 7.4) was registered on 11 accelerograph

stations, with source distances ranging from 3 to 350 km and corresponding

recorded peak accelerations ranging from 0.95 down to 0.01 g, respectively. At...

Observed variation of amplitude ratios of sP and P phases with frequency is used for a study of inelastic properties of upper mantle in the region of deep focus earthquakes. Results are compared with those derived from similar study made...

On 28 May 2004, a strong earthquake, Mw 6.5, occurred at Kojour area in northern part of Iran. During this earthquake a regional network of 146 strongmotion accelerograph stations equipped with SSA2 instruments located within 15-280 km range from...

-motion values of peak horizontal accelerations and of acceleration response spectra for periods of 0.2 and 0.3 seconds with 5% critical damping. We employed a model that allows earthquakes to occur as finite-length ruptures along faults. We assumed...
