A Study on the Design of a New Three-Dimensional Seismic Isolation Bearing Based on an Improved Genetic Algorithm for Bridge Engineering

Applied Sciences
(1) Background: In most cases, passive isolation control methods are commonly used for the seismic isolation design in bridge engineering. However, passive seismic isolation devices, due to their non-adjustable performance parameters, struggle to achieve

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

, 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.

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

Open 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,

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

Lithosphere
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

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

, 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 ...

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

Journal 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 ...

An analytical model for gas overpressure in slug-driven explosions:insights into Strombolian volcanic eruptions [PDF]

, 2012
Strombolian eruptions, common at basaltic volcanoes, are mildly explosive events that are driven by a large bubble of magmatic gas (a slug) rising up the conduit and bursting at the surface.
