PGA Peak ground acceleration Simple Lateral Mechanism Analysis (SLaMA) … standard NZS 1170.5:2004 and Module 1 of the New Zealand Geotechnical and Society Ministry of Business, Innovation and Employment’s Earthquake Geotechnical Engineering Practice series (NZGS/MBIE, 2016). These are assumed to define 100%ULS seismic, Last November’s magnitude 7.8 Kaikoura earthquake produced the strongest ground shaking ever recorded for an earthquake in New Zealand, according to new research out this week.
highest peak ground accelerations tend to occur in the west to northeast of the region, where the greatest concentrations of active faults and historical seismicity are located. Peak ground accelerations of 0.7-0.9g, and, Peak ground acceleration, which is a measure of earthquake shaking on the ground , can be expressed in vertical (PVA) and horizontal (PHA) components. It is widely used by engineers to express the intensity of ground shaking a building must be designed to withstand without collapse.
The latest version of the National Seismic Hazard Model (NSHM) for New Zealand provides probabilistic estimates of the strength of earthquake shaking that can be expected according to a user-defined time period and probability, e.g. the pe ak ground acceleration (PGA) that has a 10% chance of happening in any 50 year time window.

4/10/2017 · DEREK FLYNN/FAIRFAX NZ An instrument in Wairau measured a peak ground acceleration of 3g. The next strongest shaking was recorded during the 2011 Christchurch quake at 2.2g. Designed to measure the…
class (SC) according to the current New Zealand loading standard, NZS1170.5:2004 [9], peak ground acceleration (PGA), and peak ground velocity (PGV) for geometric mean horizontal component and peak vertical ground acceleration (PGA V). It can be seen that significant ground motions were, PGA yang merupakan singkatan dari Peak Ground Acceleration adalah percepatan batuan dasar yang timbul akibat adanya gempa. Sampai saat ini, sudah banyak berkembang rumus-rumus attenuasi untuk menghitung PGA, diantaranya: 1. Generasi pertama: Esteva (1970), Donovan (1973), McGuire (1977), Faccioli (1978), Ambraseys (1990), Campbell (1989) dll. 2.
