Seismic reflection profiles, drill-hole data, and geologic maps delimit the form of normal faults and Tertiary sedimentary rocks in the southern half of the Cache Valley basin in northern Utah. Dips of faults and sedimentary rocks were estimated from time-migrated reflection profiles by using the stacking velocities for the data. At the southern end of the basin, the East Cache fault zone is li...

During the summer of 1969, six portable seismographs were operated at 82 sites along the Intermountain Seismic Belt from southwestern Utah to northwestern Montana. This survey followed a well-known seismic belt along the eastern physiographic boundary of the Basin and Range province, and within the middle and northern Rocky Mountains. In general, the 120 microearthquakes located in this study f...

The Sonora, Mexico, earthquake of 3 May 1887 occurred a few years before the start of the instrumental era in seismology. We revisit all available accounts of the earthquake and assign Modified Mercalli Intensities (MMI), interpreting and analyzing macroseismic information using the best available modern methods. We find that earlier intensity assignments for this important earthquake were unju...

Using over 310,000 high-quality radial receiver functions recorded by the USArray and other seismic stations in the contiguous United States, the depths of the 410 km and 660 km discontinuities (d410 and d660) are mapped in over 1,000 consecutive overlapping circles with a radius of 1◦. The average mantle transition zone (MTZ) thickness for both the western and central/eastern U.S. is within 3 ...

Background Physicians need to apply new technologies in ambulatory care. At present, with regard to the extended use of information technology in other departments in Iran it has yet to be considerably developed by physicians and clinical technicians in the health department. Objective To determine the rate of use of health information technology in the clinics of specialist- and subspecialis...

Orographic precipitation of Pacific-sourced moisture creates a rain shadow across the central part of the Sierra Nevada (California) that contrasts with the southern part of the range, where seasonal monsoonal precipitation sourced to the south obscures this rain shadow effect. Orographic rainout systematically lowers the hydrogen isotope composition of precipitation (deltaD(ppt)) and therefore...

Efforts aimed at improving regional water management are often frustrated due to the paucity of reliable and consistent information. This paper assesses the scope for remote sensing information, freely available on the Internet, to help water managers in obtaining reliable and consistent information at large (sub) system level. In the Ferghana province of Uzbekistan, belonging to the Syr-Darya ...

A Multidimensional Approach to Measuring Poverty and the Assessment of Educational Poverty in Iran1   E. Aboonoori, Ph.D. * A.A. Saalem, Ph.D. ** J. Arab Yaarmohammadi ***   A multidimensional approach to measuring poverty facilitates the assessment of educational poverty as one of its several dimensions. Utilizing this approach, the overall poverty in Iran in the years of 2005 ...

Compilation of almost 200 new maximum horizontal stress (SHmax) orientations in Texas reveals a complex intraplate stress field. A large extensional stress province is associated with extensive growth faulting from northeastern Mexico to Louisiana. SHmax is subparallel to the coastline, following the strikes of the growth faults. In contrast, we observe a strike-slip/normal faulting regime with...
