The Earthquake Early Warning Display (EEWD) is a European effort led by the SED@ETHZ to build a free and open-source software to display earthquake early warning (EEW) information. The EEWD is a client-side software that: (a) supports alerts generated by the main EEW algorithms used in Europe, starting with VS, FinDer and PRESTo; (b) allows configuration of local ground-motion prediction equations (GMPEs), ground-motion to intensity conversion equations (GMICEs) and local site effects; and (c) supports future developments for configuration based on end-user requirements. In addition to real-time operations, the EEWD can replay recorded real-time earthquake alerts and play scenarios. The EEWD can be viewed as a tool to broadcast real-time or near-real-time information to end users, including, but not restricted to, EEW alerts. The EEWD was originally developed in project REAKT. Current and future versions and releases will be based on collaborative code development through GitHub (https://github.com/SED-EEW/EEWD). The EEWD is a key element of the EEW testing centre within EPOS. The EEWD is already operated by selected academic and/or research institutions and private and public stakeholders in the Euro-Mediterranean region and in Central America.
