We compute a series of finite-source parameter inversions of the fault rupture of the 2004 Parkfield earthquake based on 1 Hz GPS records only. We confirm that some of the co-seismic slip at shallow depth (<5 km) constrained by InSAR data processing results from early post-seismic deformation. We also show 1) that if located very close to the rupture, a GPS receiver can saturate while it remain...

Simultaneous in sire measurements of stratospheric NO2, HNO 3, HC1, and CH 4 from 34 to 24 km were made in August 1992 from Palestine, Texas, using the Balloon-borne Laser In-Sire Semor (BLISS) ranable diode laser spectrometer. Although the measurements of NO2, HNO3, and NO2/HNO3 agree well with gas-phase model calculations near 34 km where SAGE II data show little sulfate aerosol, this is not ...

Dunites in ophiolites form by pyroxene dissolution and olivine precipitation during melt-peridotite interaction. We present structural geochemical data on peridotites from the Batin region (Wadi Tayin massif) of Oman ophiolite, where an exceptionally large (∼9.5 km long) dunite body was sampled ICDP Drilling Project (BA4A borehole). 900–1,200 m beneath petrological Moho, this is overlain harzbu...

a r t i c l e i n f o a b s t r a c t Keywords: receiver functions lithosphere lithosphere–asthenosphere boundary mid-lithospheric discontinuity To explore how lithospheric structure varies between tectonic and magmatic terranes of the western United States, we use observations of shear-to-compressional wave conversions across lithospheric velocity interfaces. With a newly developed automatic m...

â  abastract â  the bed of the ancient lakes with having the fine granule sediments and fertile soil is a very good place for the extensive agricultural and industrial activities. the bed of ancient lake in khorramabad is a very good place for these activities. awaring of the exact limit and resolving of the morphometrical features of the same lake is very important, for environmental programmi...

Damavand volcano is located 60 km to the East North- East of Tehran. It is a dormant stratovolcano outcrop in the Alborz Mountains of northern Iran and is the highest mountain (5670 m) in the Middle East and West Asia. Mazandaran Province, one of the most populous provinces by population density, Semnan and Gorgan provinces further east are neighbours of the Damavand. Volcanism in Damavand goes...

The TTZ-South seismic profile follows the Teisseyre-Tornquist zone (TTZ) at SW margin of East European craton (EEC). Investigation results reveal upper lithospheric structure as representing NW-vergent, NE-SW striking overthrust-type, Paleoproterozoic (~1.84–1.8 Ga) Fennoscandia-Sarmatia suture. Sarmatian segment EEC comprises two crustal-scale tectonic thrust slices: Moldavo-Podolian and Lubli...

Understanding strong ground motions in the near-fault areas is important for seismic risk assessment in densely populated areas. In the past, lack of information on strong ground motion for large and moderate earthquakes led to the use of mainly far field large and moderate earthquake records in equations for calculation of the strong ground motion parameters. In this article, we collected and ...

Coseismic deformation fields of the 6 October 2008 Mw6.3 Damxung earthquake were obtained from interferometric synthetic aperture radar by using three descending and two ascending Envisat images. Significant coseismic surface deformation occurred within 20 km 9 20 km of the epicenter with a maximum displacement of *0.3 m along the satellite line of sight. We model a linear elastic dislocation i...
