JWEED v4.1r3 is a Java-based desktop application for discovering, previewing, and downloading earthquake event catalogs and seismic waveform data from FDSN-compliant data centers (for example, IRIS/EarthScope). It offers a map-driven interface and flexible search filters—time window, magnitude, depth, region, and distance/azimuth—so you can quickly locate events, choose relevant stations and channels, and assemble precise data requests. JWEED supports standard seismological formats (MiniSEED and SAC), lets you fetch station metadata and instrument response information for downstream processing, and provides waveform previews with basic filtering for quick quality checks. Designed to be cross‑platform, it runs on any system with a Java runtime, making it a practical tool for researchers, educators, and analysts who need fast, reliable access to global seismological data without writing code.
JWEEDv4.1r3 is developed by IRIS Data Management Center. The most popular version of this product among our users is 4.1. The name of the program executable file is JWEEDv4.1r3.exe.
