Seismic Hazard vs. Seismic Risk

Seismological Research Letters, 2009
The world is full of uncertainties, ranging from climate change, financial markets, natural disasters, terror attacks, and personal health to the measurements of the most fundamental elements of all: time and space. Dealing with uncertainty is a given in life, and any decision is always made under a certain degree of uncertainty.

Value at Induced Risk: Injection‐Induced Seismic Risk From Low‐Probability, High‐Impact Events

Geophysical Research Letters, 2020
The increasing number of damaging earthquakes, induced by underground injection of fluids, demonstrates the need of a structured methodology for critical thinking about and clear communication of induced seismic risk.

Seismic risk mitigation

2003
The irregularity and long time intervals between earthquakes are factors contributing to reduced awareness about earthquake risks among the public and government officials and hence to reduced allocation of resources for their mitigation. Moreover, it is not uncommon to see misallocation of resources by non- knowledgeable decision makers and ...

Near-fault seismic risk assessment of simply supported bridges

, 2020
Bridges tend to sustain excessive seismic demand (e.g. displacement) under pulse-like ground motions attributing to the effect of forward directivity, which is of high likely to occur at locations near the fault rupture.

Entropy‐based intensity measure selection for site‐specific probabilistic seismic risk assessment

Earthquake engineering & structural dynamics (Print), 2020
Intensity measure (IM) selection is a critical step in probabilistic seismic risk assessment (PSRA). In many past studies, the efficiency of an IM, which quantifies its explanatory power within a probabilistic seismic demand model, has been a predominant

Probabilistic seismic risk assessment of India

Earthquake spectra, 2020
This study presents a comprehensive open probabilistic seismic risk model for India. The proposed model comprises a nationwide residential and non-residential building exposure model, a selection of analytical seismic vulnerability functions tailored for

Quantifying the seismic risk for electric power distribution systems

, 2020
Electric power distribution systems are generally more prone to disruption from natural hazards than transmission systems due to their often less redundant circuit structures.

Multi-scale seismicity model for seismic risk

Bulletin of the Seismological Society of America, 1997
AbstractFor a general use of the frequency-magnitude (FM) relation in seismic risk assessment, we formulate a multi-scale approach that relies on the hypothesis that only the ensemble of events that are geometrically small, compared with the elements of the seismotectonic regionalization, can be described by a log-linear FM relation.
