South Atlantic continental margins of Africa: a comparison of the tectonic vs climate interplay on the evolution of equatorial west Africa and SW Africa margins

open access: yes, 2005
The comparative review of 2 representative segments of Africa continental margin: the equatorial western Africa and the SW Africa margins, helps in analysing the main controlling factors on their development.

Statistical analysis of daily seismic event rate as a precursor to volcanic eruptions [PDF]

open access: yes, 2003
We analyse time series of daily seismic event rate for the Kilauea, Hawaii, volcano between 1959 and 2000. Individual eruptions are not always preceded by an increase in event rate, and many increases in event rate do not lead to eruption.

Numerical Method for Computing Seismic Slip-Line Fields and Earth Pressure Coefficients in Cohesionless Backfills [PDF]

open access: yesLithosphere
This study introduced a novel numerical method for calculating seismic slip-line fields and earth pressure coefficients in cohesionless backfills with an inclined and rough retaining wall. By integrating the triangular slice method with the pseudo-static

On the use of low-frequency passive seismic as a direct hydrocarbon indicator: A case study at Banyubang oil field, Indonesia

open access: yesOpen Geosciences
Low-frequency passive seismic (LFPS), discussed in recent years, has emphasized a strong correlation between the spectral properties and the presence of hydrocarbon reservoirs. While the theoretical background supporting this phenomenon is still debated,

Subsurface characterization and seismic risk mapping in Padang City using HVSR and resistivity data

open access: yesJournal of Degraded and Mining Lands Management
Padang City, situated in a seismically active region, faces significant earthquake risk due to its complex geological structure. This study integrates passive seismic and geoelectrical resistivity methods to characterize subsurface conditions and map ...

Interpreting intraplate tectonics for seismic hazard : a UK historical perspective [PDF]

open access: yes, 2012
It is notoriously difficult to construct seismic source models for probabilistic seismic hazard assessment in intraplate areas on the basis of geological information, and many practitioners have given up the task in favour of purely seismicity-based ...

Role of tectonic stress in seepage evolution along the gas hydrate‐charged Vestnesa Ridge, Fram Strait [PDF]

open access: yes, 2015
Methane expulsion from the world ocean floor is a broadly observed phenomenon known to be episodic. Yet the processes that modulate seepage remain elusive.

Growth history of fault-related folds and interaction with seabed channels in the toe-thrust region of the deep-water Niger delta [PDF]

open access: yes, 2015
The deep-water fold and thrust belt of the southern Niger Delta has prominent thrusts and folds oriented perpendicular to the regional slope that formed as a result of the thin-skinned gravitational collapse of the delta above overpressured shale.

Seismic performance analysis of Kuala Lumpur air traffic control tower by friction damper [PDF]

open access: yes, 2009
In structural earthquake engineering, different kinds of energy absorption devices were invented during last 30 years (Guan et al, 2004). And more than one-decade research has shown that, on account of the virtue of no power requirement, rapid response ...
