A new analytical method for calculating the strain of oil and gas pipeline under a normal fault dislocation

Energy Science & Engineering, 2023
Oil and gas pipelines that go through an active normal fault often deform largely and cause serious disasters. On the basis of the beam theory of the elastic foundation and assuming a shape function for the deformed pipeline, a new analytical method is ...

Influence of near-fault effects and of incident angle of earthquake waves on the seismic inelastic demands of a typical Jack-Up platform [PDF]

, 2013
In this paper, the potential influence of near-fault effects and of the incident angle of earthquake waves to the seismic response of a typical jack-up offshore platform is assessed by means of incremental dynamic analysis involving a three dimensional ...

Source Parameters of the 2016–2017 Central Italy Earthquake Sequence from the Sentinel-1, ALOS-2 and GPS Data

Remote Sensing, 2017
In this study, joint inversions of Synthetic Aperture Radar (SAR) and Global Position System (GPS) measurements are used to investigate the source parameters of four Mw > 5 events of the 2016–2017 Central Italy earthquake sequence.

The Role of On‐ and Off‐Axis Faults and Fissures During Eruption Cycles and Crustal Accretion at 9°50′N, East Pacific Rise

Geochemistry, Geophysics, Geosystems, 2023
Fissures and faults provide insight into how plate separation is accommodated by magmatism and brittle deformation during crustal accretion. Although fissure and fault geometry can be used to quantify the spreading process at mid‐ocean ridges, accurate ...

Displacement/Length Scaling Relationships for Normal Faults; a Review, Critique, and Revised Compilation

Frontiers in Earth Science, 2022
The relationship between normal fault displacement (D) and length (L) varies due to numerous factors, including fault size, maturity, basin tectonic history, and host rock lithology. Understanding how fault D and L relate is useful, given related scaling

Geologic context of geodetic data across a Basin and Range normal fault, Crescent Valley, Nevada [PDF]

, 2004
Geodetic strain and late Quaternary faulting in the Basin and Range province is distributed over a region much wider than historic seismicity, which is localized near the margins of the province.

Kinematics of Normal Faults

, 2021
Continental extension is accommodated by normal faults, and fault growth is achieved by increases in length (L) and displacement (D). When normal fault length and displacement were initially studied in the 1970’s and 80’s, it was assumed that faults maintain a constant D/L ratio from initiation to cessation, growing via sympathetic increases in ...

Geomorphology of the Gubbio Basin (Central Italy): understanding the active tectonics and earthquake potential

Annals of Geophysics, 2003
The Gubbio Basin is a 22 km long, 4 km wide depression located within the North-Central Apennines fold-andthrust belt. The basin is bounded to the east by the Gubbio Fault, a W-dipping, normal fault dissecting a large Jurassic-Oligocene ...

Structural heterogeneity and permeability in faulted eolian sandstone: Implications for subsurface modeling of faults [PDF]

, 2002
We determined the structure and permeability variations of a 4 km-long normal fault by integrating surface mapping with data from five boreholes drilled through the fault (borehole to tens of meters scale).
