ShakeMap4-Web: Visualizing the ShakeMap4 Products Using a Web App

Description: 

We have developed a web application that allows users to quickly visualize the products generated using the U.S. Geological Survey ShakeMap version 4 software. The possibilities include visualizing the ground-shaking maps, the ground motion model (GMM) regression curve, the list of stations and the metadata of an event. The ground-shaking maps can be displayed both dynamically (using Leaflet maps) and statically (standard ShakeMaps). The dynamic maps can be customized with various overlays, from the contours of different intensity measures to the points of DYFI observations, with the overlays being clickable to display additional information. Furthermore, a dual-view feature allows users to view maps with different intensity measurements side by side. The Analysis view page allows users to view the regression curve of the GMM with the observed values (for macroseismic intensity, PGA and PGV). Users can use the web application to access and download all the data that contributed to the calculation of each earthquake, along with information on the seismological models used. The station list page allows the users to access information about all the stations that contributed to the generation of a specific ShakeMap. All the metadata associated with an event can be accessed through the metadata page. All the above-mentioned pages, for each specific earthquake, can be accessed through the home and archive pages. In detail, the home page shows a list of the latest events, while the archive page allows the user to show all the events that satisfy certain criteria (time range, magnitude range). The appearance of the web portal can be easily customized by replacing logos and banners. The software can be easily installed on both laptops and server computers, and users can choose between using the Docker image or using the software directly after setting up a web server (e.g., Python server, NGINX, etc.).
