This product is a one-page description of the National Earthquake Alert Centres' "FeltGrid" product. A FeltGrid is produced for any earthquake for which NEAC receives a sufficient number of community reports of shaking intensity (aka 'felt reports), via the Earthquakes@GA website (https://earthquakes.ga.gov.au). The felt reports are converted to Modified Mercalli Intensity (MMI) scale, and translated into a map of average reported shaking intensity rendered at pre-set spatial scales on Earthquakes@GA. This 'About FeltGrid' document can also be accessed through the Earthquakes@GA website, via the 'ShakeMap, FeltGrid and other downloads' listing for each earthquake under the 'Recent Earthquakes' menu.

Scanned felt reports from 1902, 1954-2010. One pdf per event.
