This paper presents site-specific probabilistic seismic hazard analysis (PSHA) results at 24 locations throughout New Zealand (NZ). Specifically, peak ground acceleration (PGA) curves for two generic soft soil conditions are considered. For specific return periods of interest, disaggregation is used to obtain the percentage contributions various sources hazard, including metrics such as mean ea...

The August 19, 1977 earthquake was one of the major earthquakes that ever occurred in Nusa Tenggara area with an impact on island Lombok, which Kuta Village. purpose this research is to determine empirical equation suitable for use Village calculate Peak Ground Acceleration (PGA) value form a distribution map. PGA can provide overview damage buildings caused by earthquake. calculation uses seve...

On February 27, 2010, the central-south part of Chile was affected by a strong ground motion of Magnitude 8.8, that induced moderate values of peak ground acceleration (PGA) on rock outcrops, in the range of 0.13g to 0.32g, while in soil deposits, a maximum PGA of 0.94g was recorded. The duration of the shaking was close to two minutes as it is substantiated by the available acceleration record...

This paper investigates the cogency of various impact models in capturing the seismic pounding response of adjacent structures. The analytical models considered include the contact force-based linear spring, Kelvin and Hertz models, and the restitution-based stereomechanical approach. In addition, a contact model based on the Hertz law and using a non-linear hysteresis damper (Hertzdamp model) ...

Seismic hazard analysis of vulnerable countries on the Alpine-Himalayan belt has great importance to be considered. Recently, Iran as one of the countries located on the stated belt has experienced a few number of severe earthquakes. A wellestablished index of how earthquakes affect buildings is by assessing probable Peak Ground Acceleration (PGA) which can be estimated by past events. For this...

This paper presents an application of neural network approach for the prediction of peak ground acceleration (PGA) using the strong motion data from Turkey, as a soft computing technique to remove uncertainties in attenuation equations. A training algorithm based on the Fletcher–Reeves conjugate gradient back-propagation was developed and employed for three sample sets of strong ground motion. ...

contrary to the long period ground motions that can be predicted and estimated, high frequency ground motions have random character and behave stochastically. stochastic modeling methods are usually used for the modeling of high frequency ground motions where there are not strong ground motion records. stochastic methods are of two kinds: in the first one, the seismic source is considered as a ...

In this study, a total of 34,893 landslides collected from the Sichuan Province China are used to reveal their spatial distribution. Correlations between distribution and five main factors [i.e. topography, rainfall, lithology, peak ground acceleration (PGA), human activity] analyzed based on Geographical Information System (GIS) platform. Topographic exert significant influence landslide occur...
