The 2018 national seismic hazard assessment of Australia: Quantifying hazard changes and model uncertainties

, 2020
Seismic hazard assessments in stable continental regions such as Australia face considerable challenges compared with active tectonic regions. Long earthquake recurrence intervals relative to historical records make forecasting the magnitude, rates, and ...

Seismic hazard assessment of Afghanistan

Journal of Seismology, 2018
Afghanistan is located at the collision boundary of the Indian, Eurasian and Arabian plates and, therefore, lies in a seismically active region. Few probabilistic seismic hazard analysis (PSHA) studies have been carried out for Afghanistan, which present only peak ground acceleration (PGA) values.

Regionally Optimized Background Earthquake Rates from ETAS (ROBERE) for Probabilistic Seismic Hazard Assessment

, 2020
We use an epidemic-type aftershock sequence (ETAS) based approach to develop a regionally optimized background earthquake rates from ETAS (ROBERE) method for probabilistic seismic hazard assessment. ROBERE fits parameters to the full seismicity catalog

Cumulative absolute velocity (CAV) seismic hazard assessment for Taiwan

Journal of earthquake engineering, 2020
Cumulative absolute velocity (CAV) is a ground motion intensity measure that is considered more indicative of structure damage than other intensity measures (e.g., PGA).

Probabilistic Seismic Hazard Assessment Using Legacy Data in Georgia

Seismological Research Letters, 2020
The Caucasus has a documented history of cataloging earthquakes stretching back to the beginning of the Christian era. Instrumental seismic observation in the Caucasus began in 1899, when the first seismograph was installed in Tbilisi, Georgia.

Quantitative Seismic Hazard Assessment

2007
We analyze the ingredients required for deterministic wave propagation simulation in order to estimate more accurately ground motion in terms of amplitude, frequency content and duration. Building maps of expected ground motion before a catastrophic event for various scenarios may help design ways to mitigate impacts of ground vibrations as well as ...

Seismic Hazard Assessment

2014
This chapter describes the fundamentals of seismic hazard assessment that constitutes the basis in the definition of seismic design forces. The classical probabilistic and deterministic hazard assessment methods are introduced with emphasis on their elementary components.

A New State‐of‐the‐Art Platform for Probabilistic and Deterministic Seismic Hazard Assessment

Seismological Research Letters, 2019
A new computational platform for seismic hazard assessment is presented. The platform, named SeismicHazard, allows characterizing the intensity, uncertainty, and likelihood of ground motions from subduction‐zone (shallow interface and intraslab) and ...

Seismic Hazard Assessment and Land Use Analysis of Mangalore City, Karnataka, India

Journal of earthquake engineering, 2019
This article presents a combined seismic risk assessment of Mangalore city, considering seismic hazard and Land Use (LU) patterns. Probabilistic seismic hazard analysis was carried out considering different source models and attenuation relations to ...

Seismic hazard assessment in Panama

Engineering Geology, 1997
Abstract In this study we have created a set of three iso-acceleration maps for the Isthmus of Panama. These maps represent the expected peak ground acceleration (PGA) values, at soil sites, for annual exceedance probabilities of 0.004, 0.002 and 0.001, which correspond to return periods of 250, 500 and 1000 years, respectively.
