Abstract. Modern satellite networks with rapid repeat-cycles allow for near-real-time imaging of areas impacted by natural hazards such as mass wasting, flooding, and volcanic eruptions. Publicly accessible multi-spectral datasets (e.g. Landsat, Sentinel-2) are particularly helpful in analyzing the spatial extent of disturbances, however, the datasets are large and require intensive processing on high-powered computers by trained analysts. HazMapper is an open-access hazard mapping application developed in Google Earth Engine that allows users to derive map and GIS-based products from Sentinel or Landsat datasets without the time- and cost-intensive resources required for traditional analysis. Case studies are included for the identification of landslides and debris flows, wildfire burn extents, pyroclastic flows, and lava flow inundation. HazMapper is openly-available to the public and is intended for use by both scientists and non-scientists, such as emergency managers and public safety decision-makers. It is the intent of the authors to continue to develop HazMapper with additional capabilities. Collaboration on this effort is encouraged.

Short summary
For many decades, natural disasters have been monitored by trained analysts using multiple satellite images to observe landscape change. This approach is incredibly useful, but our new tool, HazMapper, allows researchers and the scientific-curious public a web-accessible cloud-based tool to perform similar analysis. We intend for the tool to be used both in scientific research and to provide rapid response to global natural disasters like landslides, wildfires, and volcanic eruptions.
