Reports submitted by the public showing how people experienced the shaking. This data helps our scientists understand an earthquake's real-world impact. Share your experience of the earthquake by submitting a detailed felt report.
When it comes to earthquakes, the ground shaking that people feel is important to us, and contributes to our data source. By submitting a Felt Report, our seismologists learn more about the intensity of shaking that people experienced during an earthquake.
There are two ways we collect Felt Reports, Felt Rapid reports which allow people to choose from a cartoon representation of shaking, and Felt Detailed reports, which gather rich information from a survey questionnaire. Felt RAPID data can be accessed via the mobile app or the GeoNet website. The button is called “Felt It”.
Felt Detailed is accessible through the GeoNet website, inside the relevant earthquake’s page. You can access Felt RAPID data through the GeoNet API
The Shaking Layers Map shows ground shaking models produced from a combination of strong motion measurements and ground motion modelling that estimate the shaking intensity around New Zealand. The maps can change over time as new data becomes available. Following larger earthquakes, GNS Science earthquake experts may also update shaking maps using new scientific information, and these maps can evolve significantly from the first automatically generated map.
Science is a collaborative effort; Shaking Layers is a GNS Science product supported by GeoNet and the Rapid Characterisation of Earthquakes and Tsunami (R-CET) programme. Read more about Shaking Layers maps.

Other hazards caused by earthquakes depend on the strength of ground shaking and how the earthquake deforms the earth around it. These can include tsunami, landslide, liquefaction, and land deformation and movement.
