A strategy to address the task of seismic micro-zoning in landslide-prone areas [PDF]

Advances in Geosciences, 2013
As concerns landslide prevention and mitigation policies at the urban scale, the ability of Geographical Information Systems (GIS) to combine multi-layered information with high precision enables technicians and researchers to devote efforts in managing ...

A comparison of ground motions predicted through one‐dimensional site response analyses and three‐dimensional wave propagation simulations at regional scales

Earthquake Spectra, Volume 40, Issue 2, Page 1215-1234, May 2024.
One‐dimensional (1D) site response analysis (SRA), which considers vertically propagating seismic waves from the bedrock to the surface, has been a common technique among geotechnical engineers to examine site‐specific ground shaking. However, observations from past earthquakes and analytical studies indicate that idealizations ingrained in 1D SRA may ...

Liquefaction maps in Babol City, Iran through probabilistic and deterministic approaches

Geoenvironmental Disasters, 2018
Background During an earthquake, significant damage can result due to instability of the soil in the area affected by internal seismic waves. Liquefaction is known as one of the major causes of ground failure due to the earthquake.

State‐of‐the‐Art Seismic Studies of Loess Tunnels in China

Advances in Civil Engineering, Volume 2024, Issue 1, 2024.
Large earthquakes occur frequently around the world. Due to the fragility of loess, the effects of seismic events on loess tunnel projects have received considerable in‐depth research attention. In this paper, we systematically review recent seismic research on loess tunnels and highlight deficiencies that require further study with a focus on the ...

Width of surface rupture zone for thrust earthquakes: implications for earthquake fault zoning [PDF]

Natural Hazards and Earth System Sciences, 2018
The criteria for zoning the surface fault rupture hazard (SFRH) along thrust faults are defined by analysing the characteristics of the areas of coseismic surface faulting in thrust earthquakes.

Enhancing Seismic Performance: A Comprehensive Study on Masonry and Reinforced Concrete Structures Considering Soil Properties and Environmental Impact Assessment

Advances in Civil Engineering, Volume 2024, Issue 1, 2024.
Approximately 20,000 people are killed annually on average by building and infrastructure collapses and failures caused by seismic activities. In earlier times, seismic design codes and specifications set minimal requirements for life safety performance levels. Earthquakes can be thought of as recurring events in seismically active areas, with severity

Simple Method to Develop Seismic Microzonation Maps for Cities in Northern Haiti and Elsewhere

International Journal for Service Learning in Engineering, Humanitarian Engineering and Social Entrepreneurship, 2015
Many developing nations are situated in zones of high seismicity where earthquakes can lead to widespread property loss and loss of life.  Similar-sized earthquakes are not nearly as devastating in developed nations because of access to state-of-practice engineering methods.
