Disposition of magmatic eruptions and fault distribution in northwestern Saudi Arabia using pseudo-depth slice magnetic anomaly

This study presents the disposition of magmatic eruptions with a fault distribution in northwestern Saudi Arabia, where intensive magma invades the lithosphere. Structural and magmatic features are traced at successive depths through high-resolution magnetic anomaly pseudo-depth slices. The total horizontal gradient technique is applied to pseudo-depth slice magnetic anomalies to enhance the linear trends of faults and related magmatic activity. A comprehensive cross-section constructed from the projection of gradient horizontal maxima relative to pseudo-slices allows the visualization of the vertical behavior of faults and magma sources. Three major fault systems were identified, primarily aligned in the N–S, NE–SW and NW–SE directions. They are characterized by increasing length and width with depth. The N-S fault system is a major non-planar deep system throughout the area, affected by the NW–SE and NE–SW deep discontinuities. The evolution of these discontinuities with depth successfully shows magma uprising zones represented by a circular horizontal gradient, which starts to appear at a depth of 4500 m with a vertical continuity to the surface. They are interpreted as possible locations of ascending magma chambers or vents. The disposition of these magma sources with fault distribution can show a close relationship between the fault systems and the magma eruptions. The interpreted magma vents appear where the NE-trending transform faults intersect the NW or N–S fault zone. These intersections may represent weak zones that act as vertical conduits through which magma discontinuously erupts into the overlying crust, forming major volcanic fields in the eastern Red Sea.

Embarking: The Pittsburgh Survey, Workers’ Compensation, and the First Blush of Fame

In 1907, Crystal Eastman began a temporary job investigating industrial accidents with the Pittsburgh Survey, a comprehensive study of urban industrial life organized by Paul Kellogg and Edward Devine, financed by the newly formed Russell Sage Foundation. The project involved established leaders, such as Florence Kelley and John R. Commons, as well as young visual artists, including Lewis Hine and Joseph Stella, and brought a new generation of educated women into professional work in social welfare. Eastman’s study, later published as Work Accidents and the Law (1910), resulted in her appointment by Governor Charles Evans Hughes to chair New York’s new commission on employer liability in 1909. There, she proposed to overhaul common law standards, shifting to a no-fault distribution of risk and loss shared by workers, businesses, and consumers. The resulting legislation failed a constitutional challenge in 1911 but laid the groundwork for successful workers’ compensation laws in New York State and elsewhere.
