Shaking Layers Dataset
Database
The Shaking Layers tool produces maps of ground shaking minutes after an earthquake of magnitude 3.5 or above has occurred in New Zealand. These maps combine strong motion measurements recorded at seismic stations with ground motion modelling to estimate shaking intensity anywhere in the country.
As more data and scientific information become available, Shaking Layers maps are updated and therefore can change over time (from minutes to days to months) following an earthquake. The maps provide information on macroseismic intensity, peak ground acceleration, peak ground velocity and spectral acceleration at several periods. Outputs include a dynamic map (GeoNet website(external link)) and several types of outputs on the shaking layer website, including static maps, json files and GIS layers.
Science is a collaborative effort; Shaking Layers is a GNS Science product supported by GeoNet(external link) and the Rapid Characterisation of Earthquakes and Tsunami (RCET) programme(external link).
