Use of Felt Rapid Reports as a reliable data source in the production of Earthquake Intensity Maps

Crowdsourcing has the potential for use in a wide range of hazard applications through timely collection of large quantities of data. One example is GeoNet’s Felt Rapid Report (FRR) data (up to 61,000 reports collected within 15 minutes of an earthquake). Members of the public indicate the intensity of shaking they experienced by selecting from a series of cartoons aligned with values on the Modified Mercalli Intensity scale. My aim is to develop FRR data into a valuable data source by quantifying uncertainties and exploring a range of spatial aggregation units to make it usable for community and scientific purposes.
